[PHP] Freeing memory for DOMDocument
I'm running through a large dataset and am generating/manipulating XML
documents for each record. What's happening is that after a while, I
get a fatal error saying:
Fatal error: Allowed memory size of 167772160 bytes exhausted (tried
to allocate 32650313 bytes)
Each XML file I generate (an manipulate) can range from just a few
megs to upwards of 35 megs. Judging from the error above, it looks
like the memory for the DOMDocument objects I instantiate is not
getting freed; it just continues to stay in memory until the memory is
completely exhausted. The method (in my object) I am using to
instantiate a new DOMDocument is as follows:
protected function createCleanDomDocument()
{
/*
if(( isset( $this->oDomXPath )) && ( !is_null( $this->oDomXPath )))
{
unset( $this->oDomXPath );
}
if(( isset( $this->oDomDocument )) && ( !is_null( $this->oDomDocument )))
{
unset( $this->oDomDocument );
}
*/
$this->oDomDocument = new DOMDocument( '1.0', 'iso-8859-1' );
$this->oDomXPath= new DOMXpath( $this->oDomDocument );
}
which is used in both the constructor of my object and in a few other
places. I would think that when the new DOMDocument is instantiated,
the memory used for the old value would get freed. As you can see,
I've even tried to unset the variables but that doesn't seem to help
matters much, either.
Does anyone know how (or even if) I can explicitly free the memory
used for the DOMDocument? Any help/advice would be greatly
appreciated!
thnx,
Christoph

[PHP] Create image from HTML

"'"; Andrew is right. If you use the above query, that will probably get you going. But in general, aliases allow you to reference a column as something other than what it is named in the table's schema. It would allow you to do something along the lines of: SELECT Employee.Name AS EmployeeName, Employer.Name AS EmployerName FROM blah blah blah. In the above example, the column "Name" is ambiguous. By defining an alias, it removes the ambiguity and allows mysql to return the value of both columns. In your code, you would just reference it using: $rowData['EmployeeName'] $rowData['EmployerName'] I hope that helps explain aliases a bit. thnx, Christoph -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Symlinks and ownership
Is there a reason why you can't programatically set ownership of a
symbolic ink? The following code
if( symlink( TARGET, LINK ))
{
echo 'Successfully created ' . LINK . "\n";
if( @chown( LINK, NEW_UID ))
{
echo 'Successfully changed ownership for ' . LINK . "\n";
if( @chgrp( LINK, NEW_UID ))
{
echo 'Successfully changed group for ' . LINK . "\n";
}
}
}
echos out:
Successfully created XXX
Successfully changed ownership for XXX
Successfully changed group for XXX
yet when I go take a look at it in the directory, the group for the
link has not been changed to what I set it to. Is that not something
you can do for symbolic links programatically?
thnx,

Well, just as a general rule, you'll want to validate all possible
user input. That includes checking whether or not particular input
has been defined, whether or not it is valid for it's intended use and
whether or not it's malicious.
Applying that guideline to your situation, I would check to see if:
* the input is set
* the input is numeric
If either or those are not true, I would default the value to 1 since
division is being used. e.g.,
$iVar = 1;
if(( isset( $_REQUEST['MY_NUMBER'] ) && ( is_numeric(
$_REQUEST["MY_NUMBER']))) {
$iVar = $_REQUEST['MY_NUMBER'];
}
$iCalculatedValue = $x / $iVar;

It does. But I'm looking to use this on an inherited framework that, unfortunately, includes very little PHPDoc comments. Considering how large the codebase is, it'd be quicker for me to write this functionality (to at least give us something to reference) than it would be to add the necessary comments.

[PHP] un-de-re-deprecation
http://us.php.net/manual/en/language.operators.type.php The instanceof operator was introduced in PHP 5. Before this time is_a() was used but is_a() has since been deprecated in favor of instanceof. Note that as of PHP 5.3.0, is_a() is no longer deprecated. http://us.php.net/manual/en/function.is-a.php Changelog Version Description 5.3.0 This function is no longer deprecated, and will therefore no longer throw E_STRICT warnings. 5.0.0 This function became deprecated in favour of the instanceof operator. Calling this function will result in an E_STRICT warning. "Oh, never mind. All that refactoring you did to take in to account the deprecation of is_a(), well, sorry 'bout that. We were a little not right in the head when we originally made that decision. You can go ahead and change all that code back now if you like..."

[PHP] fileinfo returning wrong mime type for Excel files
Consider the following:
$finfo = finfo_open( FILEINFO_MIME, '/usr/share/file/magic' );
if( $finfo )
{
$mimeType = finfo_file( $finfo, '/path/to/my/excel.xls' );
finfo_close($finfo);
}
echo $mimeType;
When I run the above, it echoes out "application/msword". Why? I
understand that both excel and word are part of the office suite but
why isn't it returning "application/excel" as it should? As far as I
can tell, we're using the most up to date version of fileinfo for PHP
5.2.5. Is there something else I'm missing? Or doing wrong?

You don't even need to do that; it'd generate way too much redundant
code. Instead, just use interfaces. The only real downside is that
all the classes you want to decorate would need to implement them and
that would cause a wee bit of ugliness in the code/class declaration.
But if you are fine with that, it's a perfect solution, particularly
since you can type hint interfaces.
interface iDecorator {}
class Thing implements iDecorator {}
class Timer
{
public static function time( iDecorator $obj ) {}
}
$obj = new Thing();
Timer::time( $obj ); // $obj becomes a Timer obj with $obj inside it
$obj->thingMethod(); // Timer passes call to Timer->obj

[PHP] stdout as input
I've read the section in the docs about i/o streams and other related sections I was able to find but couldn't figure out how to do what I need. From the command line, I'm trying to pipe stdout in to my php script which should then see it as input.

"\n\n"; I've also tried php://stdout and php://input. I also tried eschewing the php:// pseudo protocol and popen altogether and going with the STDIN and STDOUT constants. None of that worked.

[PHP] json_encode() behavior and the browser
I'm curious if the behavior of json_encode() is influenced by the browser at all. I have a page that returns search results. If I access the page and perform a search using Chrome, the following error shows up in the log: PHP Warning: json_encode() [function.json-encode]: Invalid UTF-8 sequence in argument in [PAGE] on line [LINE] If I access the page and perform a search, the exact same search using the exact same parameters, using Firefox then I get the expected results. When I var_dump() the return value of json_encode(), I see that it is a null in the case where I accessed using chrome but the expected string in the case where I accessed using firefox. In both cases, the input array is identical. Given the identical input and different output, the only thing I can figure is that the headers sent to the server as part of the request figure in to how json_encode() behaves. Is that the case? Or am I barking up the wrong tree? To be clear, I'm not talking about how the browser ultimately handles the json encoded data. I know there can be issues with that.

What I don't understand is how json_encode() is taking the *exact same input* and behaving differently (breaking in one case, working in another) depending on the browser being used. And taking your statement that json_encode() works only in utf-8 as a given, how can I guard against the different behaviors on the backend, where json_encode() is getting executed. Should I do some kind of header sniffing prior to every call to json_encode() and massage the data accordingly depending on what I find? That seems somewhat excessive.

''; yields the following output : Array ( [message] => lkjlkjklj [buttons] => Array ( [button] => This is my free form text ) ) So I get the CDATA but I don't get the "name" attribute for the button. When not using LIBXML_NOCDATA: echo '' . print_r( json_decode( json_encode((array)simplexml_load_string( $previewString, 'SimpleXMLElement', LIBXML_NOBLANKS )), 1 ), TRUE ) . ''; yields the following output : Array ( [message] => Array ( ) [buttons] => Array ( [button] => Array ( [@attributes] => Array ( [name] => Add Me ) ) ) ) I get the attributes but not the CDATA. Looking at the doc page for simplexml_load_string() (http://us.php.net/manual/en/function.simplexml-load-string.php and http://us.php.net/manual/en/libxml.constants.php), I don't see a way to get access to both.

[PHP] Case insensitive ksort
I looked in the docs but didn't see anything regarding case insensitivity and I fear the functionality doesn't exist. I'm just hoping I'm looking in the wrong place. Is there a way to get ksort to work without regard to case? When I sort an array using ksort, all the upper case keys end up at the top (sorted) and all the lower case keys end up at the bottom (sorted). Ideally, I'd like to see all the keys sorted (and intermixed) regardless of case. Am I going to have to do this manually? Or is there an internal php command that will do it for me? thnx, Christoph -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] json_encode/json_decode, take 2
The string used below in "$myArrEncoded" is generated in javascript, after
creating the structure and spitting out:
var JSONVar = javascriptVar.toSource();
I can eval JSONVar and work with it as I would be working with the original
javascriptVar so I know the transition back and forth from a structure to a
string isn't causing problems. The problem is when I try to work with the
string in PHP.
Here is my code:
';
echo '$myArr encoded: ' . $myArrEncoded . '';
try {
echo '$myArr decoded: ' . print_r( json_decode( $myArrEncoded, TRUE
), TRUE ) . '';
} catch( Exception $e ) {
echo 'Error: ' . var_dump( $e );
}
?>
When I run it, I get the following output:
string(587) "({Salary:{'50-70K':{filterType:"range",
fieldName:"SALARY", fieldValueLabel:"50-70K", lowerValue:"50",
upperValue:"70", inclusive:"BOTH"}},

Why isn't json_decode() converting the string to an array? Is there
something extra in there that json_decode() can't deal with? I can work
with it fine in javascript... :(

Running that I found that
if( isset( $myArray[$key] ))
is faster than
if( array key exists( $key, $myArray ))
is faster than
if( $myArray[$key] )
To be honest, I was surprised. I would have thought that if( $myArray[$key]
) would have been the fastest way to check. I'm wondering if those in the
know could explain why it's the slowest and also where the discrepancies
come from w/r/t the difference in the amount of time it takes to make each
check.

[PHP] sprintf() oddness
Why does sprintf( '%.03f', 0.1525 ) return 0.152 while sprintf( '%.03f', 0.1575 ) return 0.158? The 4th significant digit in both cases is '5' but in the first case, it's rounded down but in the second case it is rounded up. Is sprintf() basing it's decision on the value of the 3rd significant digit? If so, why? Shouldn't rounding decisions be based on subsequent digits and not preceding ones?

[PHP] Change case of HTML tags
I've been looking through the docs but haven't found an internal function that does what I'm looking for. Perhaps I missed it? Or perhaps someone can point me in the right direction?

So becomes and so on; I don't want anything else touched. This may seem kind of silly but I'm working with an XMLDocument object in javascript and when I serialize it to string format, for some reason all the tags are made into uppercase. I'm taking the serialized string, posting it back to the server and using it on the back end. I figure that since I can make it so that the serialized string is lower case on the front end, perhaps I can convert it on the back. Any ideas/pointers? thnx, Christoph

I'm not saying it's not expected behavior. In fact, that exactly what I would expect based on what the docs say. I'm just asking if there is another way to get the script file name that's calling the function. I need it primarily for debugging purposes. I've got a single function that's called by several files. And instead of modifying all the files calling the function to add logging, it would be nice to just modify the function, adding logging only to it to also include what script called it.

Not wanting to re-invent the wheel, I'm wondering if there is a package out there that can read in an HTML file and allow you to manipulate and dissect it much like you can in javascript?

[PHP] DOMDocument->getElementById() isn't working
Here is the input string I'm using:
{display ref="BYOPPageMetaData" id="3"}
{display ref="ResourceList" id="0"}
And here is the PHP stub I'm using:
$oDOMDocument = new DOMDocument;
$oDOMDocument->preserveWhiteSpace = false;
$oDOMDocument->formatOutput = true;
$oDOMDocument->validateOnParse = true;
if( $oDOMDocument->loadHTML( $cleanedFile ))
{
$aLayoutNodes = $oDOMDocument->getElementsByTagName("div");
if( 0 < count( $aLayoutNodes ))
{
echo 'Found [' . count( $aLayoutNodes ) . '] nodes.' . "\n";
foreach( $aLayoutNodes as $oLayoutNode )
{
$sLayoutId = $oLayoutNode->getAttribute( 'id' );
echo 'Current Id: [' . $sLayoutId . ']' . "\n";
}
}
$oCustomNode = $oDOMDocument->getElementById( "custom" );
echo 'Tag: ' . $oCustomNode->nodeValue . "\n";
}
Getting the elements by tag name, while iterating through the list I see
that one of the nodes has an id of 'custom'. However, when I try to get the
element directly using getElementById(), it doesn't return the node
properly. Am I doing something wrong?
Also, as an aside, one thing that I found odd is that count( $aLayoutNodes )
shows as 1 even though more are found. Huh?
thnx,

array_merge() clobbers the value of a particular key if that key
exists in any of the arrays that appear later in the argument list for
that function. If I want it so that I can merge arrays but make it so
that all the values are retained, I need to write a function myself.
So basically I end up with something that approximates:
function array_merge_retain( $arr1, $arr2 ) {
$retval = array();
foreach( $arr1 as $key => $val ) {
$retval[$key][] = $val;
}
foreach( $arr2 as $key => $val ) {
$retval[$key][] = $val;
}
return $retval;
}
(there would be a lot of other stuff going on, error checking and
such, but the above is just bare bones).
What that gives me is an array where the values for keys that appear
in both arrays are retained. The above function is all well and fine,
I suppose, but when the keys were created by PHP, I don't really care
about retaining the key. If the key was created by PHP, i'd just do
an array_push() instead of explicitly defining the key, as I am in the
above function. That way, in the end, the merged array would contain
arrays for values for only those keys that were user defined.
Consider the following example:
$myArr1 = array( 'joe' => 'bob', "0" => 'briggs', 'whatever', 'whereever');
$myArr2 = array( 'joe' => 'that', "0" => 'other', 'this', 'there');
the values 'whatever' and 'this' both have a key of 1 while 'wherever'
and 'there' both have a key of 2. When merged, I envision the new
array looking something like this:
Array
(
[joe] => array( bob, that )
[0] => array( briggs, other )
[1] => whatever
[2] => whereever
[3] => other
[4] => there
)
but my function above would create an array that looks like this:
Array
(
[joe] => array( bob, that )
[0] => array( briggs, other )
[1] => array( whatever, this )
[2] => array( whereever, there )
)
perhaps I am approaching this a$$backwards. I just wanted to keep the
merged array in more or less the same form as the original arrays in
the sense that those values that didn't originally have a user defined
key are not grouped together like those that did originally have a
user defined key.
thnx,
Christoph

[PHP] How can I do this -- method chaining
Constructors return the object, correct? If so, how can I do this:
class Bob {
private $blah;
_construct( $blah ) {
$this->blah = $blah;
}
public getBlah() {
return $this->blah;
}
}
echo Bob( 'Hello!' )->getBlah();
When I try that, I get the message "Undefined function Bob". I've also tried
echo new Bob( 'Hello!' )->getBlah();
echo (new Bob( 'Hello!' ))->getBlah();
but PHP didn't like either of those at all. Is it just not possible
what I'm trying to do?
I'm using PHP5.2.1

It seems to me that 1 and 3 aren't necessarily mutually exclusive. I believe that you can use your own error classes in php's try/catch functionality.

[PHP] Possible using XPath?
Let's say I have the following structure: By using the following XPath query //[EMAIL PROTECTED]"gc3"]/child I can get the child nodes of "gc1". But what I'd really like to get is the sub branch/path going back to the root. So instead of just returning the two nodes I'd like to be able to return the sub branch/path Is that possible? Or is this something I'd have to do programatically using the nodes returned by the XPath query?

Thanks for the response. However, I must be doing something wrong
here. The test script below isn't doing what I'm expecting:
$xml = 'Great Grand Child
1Great Grand Child 2Great Grand Child 3Great Grand Child 4Great Grand Child
5Great Grand Child 6Great Grand Child 7Great Grand Child 8';
$doc = new DOMDocument('1.0', 'UTF-8');
$doc->loadXML( $xml );
$xpath = new DOMXPath($doc);
$nodeList = $xpath->query("//[EMAIL
PROTECTED]'gc3']/child/ancestor-or-self::*");
echo 'Got list list of [' . $nodeList->length . '] nodes:';
for ($i = 0; $i < $nodeList->length; $i++) {
echo $nodeList->item($i)->nodeValue . "\n";
}
When I run the XPath query through XMLSpy, the correct nodes are
returning. However, when I run it through DOMXPath->query() (or
evaluate() for that matter), it doesn't seem to be returning the
correct nodes.
What's going wrong?
thnx,

[PHP] Problem with DOMElement/Node
Could someone explain to me what I'm doing wrong?
I'm trying to get an element from one DOMDocument and append it to a
different DOMDocument. The (simplified) output of saveXML() from the
first DOMDocument is as follows:
12
Here is a snippet of code:
createElement( 'menu' );
$oRootNode->setAttribute( 'id', 'root' );
$oRootNode->setIdAttribute( 'id', TRUE );
$oRootNode->setAttribute( 'style', $sStyle );
$oRootNode->setAttribute( 'width', $iWidth );
$oRootNode->setAttribute( 'target', $sTarget );
$oRootNode->setAttribute( 'indent', $iIndent );
$oXmlDocument->appendChild( $oRootNode );
$oNewChildEl = $oFirstDoc->getElementById( 'root' );
$oRootNode->appendChild( $oNewChildEl );
?>
I'm printing out what $oNewChildEl is to see if it's not returning the
proper element, using
echo '[' . $oNewChildEl->tagName . ']' . var_dump( $oNewChildEl );
and I'm seeing:
object(DOMElement)#1055 (0) { } [BranchRoot]
so it does look like it's returning the proper DOMElement. But even
so, I'm getting a fatal error when $oRootNode is trying to
appendChild(). Specifically, the error I'm getting is
Fatal error: Uncaught exception 'DOMException' with message 'Wrong
Document Error'
What's going on? It doesn't seem like I'm doing anything wrong but
something is causing the problem and I apparently do not understand
exactly what.
Could anyone lend any insight as to what's going on? And what I might
do to get what I need done?
thnx,
Chris

[PHP] Method chaining off constructors
Is there a reason why you can't do method chaining off of constructors?
Consider the following class:
class bob
{
public function __construct()
{
echo 'Constructor()';
}
public function one()
{
echo '->one()';
return $this;
}
public function two()
{
echo '->two()';
return $this;
}
}
This works:
$bob = new bob();
$bob->one()->two();
whereas this doesn't.
$bob = new bob()->one()->two();
Why? I thought constructors returned the object?
thnx,
Christoph

[PHP] Object overhead vs. arrays
I knew that there would be some overhead when working with objects vs
working with arrays, but I didn't expect this much. Is there some
optimization that I could do to improve the performance any? While
the script below is just a benchmark test script, it approximates
functionality that I'm going to need to implement. Ultimately, I need
to iterate through a large amount of data and am wondering if perhaps
I should encapsulate the data in objects (which closer represents the
underlying data) or if I should encapsulate it in arrays. Based on
what I'm seeing in this benchmark script, it seems like it should be
the latter...

[PHP] A few questions about PHP's SOAP module
* I'm trying to better understand the 'classmap' option for the SoapClient class. Is it used to define the class of an instantiated object which will be passed as an argument to the server's function call? So, as a very simplistic example, it might go something like this: sStockSymbol = $sStockSymbol; } } $oObj = new MyClass( 'ibm' ); $oClient = new SoapClient( $sWSDL_URI, array( 'classmap' => array( 'StockSymbol' => 'MyClass' ))); $oClient->getStockValue( $oObj ); ?> Am I even close? Now, what happens if one of the required arguments to the server function is a variable that has a hyphen in it? Is there any way I can get around that since PHP doesn't allow you to define variables with hyphens? * Whether using class/objects to pass parameters to a server function (assuming I have the above correct) or arrays, how can you define further attributes for each parameter? Is that even possible? So here is an example of a SOAP message that the server is expecting: http://schemas.xmlsoap.org/soap/envelope/"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xmlns:xsd="http://www.w3.org/2001/XMLSchema";> Var1 Value live Node Value Node Value Node Value Node Value Node Value How can I set up the attributes illustrated above? Encoding, node-type, etc? Is that possible? * Finally, is there a really good and/or comprehensive tutorial and/or write-up on PHPs SOAP module? The documentation is pretty spartan and what I have found doesn't really go in to much depth. Any help would be greatly appreciated! thnx, Christoph -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] More SOAP questions. Also, SOAP bug? Or just me? (long)
* I'm not sure if this is a bug (unlikely) or if it's just me (highly
likely). Given the following WSDL,
http://schemas.xmlsoap.org/wsdl/soap/";
xmlns:soap12="http://schemas.xmlsoap.org/wsdl/soap12/";
xmlns="http://schemas.xmlsoap.org/wsdl/"; name="TestTesting"
targetNamespace="urn:/test/testing">
http://www.w3.org/2001/XMLSchema";
xmlns="urn:/test/testing/soap/security/types"
elementFormDefault="qualified"
targetNamespace="urn:/test/testing/soap/security/types">
http://www.w3.org/2001/XMLSchema";
xmlns="urn:/test/testing/types" elementFormDefault="qualified"
targetNamespace="urn:/test/testing/types">
http://schemas.xmlsoap.org/soap/http"/>
http://www.testserver.com"/>
I have the following code for calling the "ServerOperation" operation:
$oClient = new SoapClient( $sWSDL_URI,
array( 'trace' => TRUE,
'exceptions' => FALSE ));
$aParameters = array( 'authentication' => array( 'username' => 'user',
'password' => 'pass' ),
'stringvar1' => 'here',
'stringvar2' => 'there',
'data-array' =>
'Bob' );
$oClient->ServerOperation( $aParameters );
But running that gives me a soap fault. Apparently the "data-array"
node isn't populated in the SOAP message body. I actually get a
different soap fault if I try to use classmap, but that is part of a
different question asked below. So I then add in:
echo 'Types: ' . print_r( $oClient->__getTypes(), TRUE ) . '';
and it turns out that the "data-array" definition in the WSDL is
getting translated as the following structure:
[XX] => struct data-array {
any;
}
Umm, huh? What's going on there? Why is the SoapClient the part of
the namespace included in the definition for the type in the WSDL
() and turning the "any" into an
attribute of the structure? So in order to get the "data-array" node
in the SOAP message body, I have to change the parameters definition
to:
$aParameters = array( 'authentication' => array( 'username' => 'user',
'password' => 'pass' ),
'stringvar1' => 'here',
'stringvar2' => 'there',
'data-array' => array( 'any' =>
'Bob' ));
That seems exceptionally silly to me. Is this a bug in the
SoapClient's translation of the WSDL? A problem with the WSDL? Or a
problem with my (albeit simplistic) code and is something I can and
should get around using proper attributes? If it's the latter, how
can I define attributes for the various nodes?
* Now, this question is sort of an extension of the issue above. If
instead of passing in an array, I use the classmap option for the
SoapClient, I get a different soap fault but it's based on the same
problem. If instead my code looks like this:
$oClient = new SoapClient( $sWSDL_URI,
array( 'trace' => TRUE,
'exceptions' => FALSE,
'classmap'=>
array( 'ServerOperation' => 'MyClass' )));
and populate public properties of an instance of MyClass with the
appropriate values, the fault message I get then is instead "Encoding:
object hasn't 'any' property". By setting the "data-array" property
(using variable gymnastics because PHP doesn't like dashes in variable
names) as an array with an "any" key, just as I did above when using
the array, then the fault goes away. However, it then gives me a
different fault but that is another question asked below. So again,
is there something different I should be doing that can or does deal
with this? Is it a bug?
* Finally, the last soap fault message I'm getting (alluded to above)
is one that is telling me that there was no POST data. I see that the
SOAP envelope/body is populated with all the nodes and data the
operation is expecting but didn't ultimately get. It seems to me that
when the SoapClient is making the remote function call, it is passing
the data as part of a GET. Is it possible to tell the soap client
that it should use POST instead? I don't see anything in the
documentation the deals and/or discusses this.
Any help and/or advice would be greatly appreciated!
thnx,
Christoph

It seems like this is having an additional affect of not allowing the
'classmap' functionality to work properly. When I do:
$oClient->__getLastResponse()
I see the full SOAP message XML and it appears to be properly formed.
So (unless I am profoundly misunderstanding how classmap works) it
should be when I try to do:
$oResponse = $oClient->ServerOperation( $aParameters );
the $oResponse object should be instantiated with it's attributes
populated with the proper values, corresponding with the various
nodes/values that appear in the XML SOAP response. The problem is, it
isn't. I've tried creating __get() and __set() methods in the class
to see if they are being called and/or what is getting passed in (if
anything) and I'm not seeing any of my debug outout. Additionally, if
I run
var_export( $oResponse );
I am seeing:
MyResponseClass::__set_state(array(
'any' => '',
))
That doesn't seem right. Further, if I try to access the "any"
property of the object, there is no value (as illustrated above).
It's as if nothing was done with the XML SOAP response w/r/t defining
the classmap option.
So what's going on? Am I doing something wrong? Am I totally
misunderstanding something here?
thnx,
Christoph

I'm looking for a decent (I don't really need a ton of bells and whistles) freeware app but my searches thus far have proven fruitless. thnx, Christoph -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Personally, I always use the accessor methods. For the most part I agree with Stut -- they don't add much value. Where it does add value, though, is in the eventuality you ever need to change the attribute to a more restrictive visibility. If you ever run across this need (and I have a couple of times), the only thing affected is the class; you don't have to worry about changing all of your code using that class. Conceptually, it is my preference to keep a class as much of a black box as possible and accessor methods allow for that. thnx, Christoph -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] SOAP call
Is there a way to call a SOAP function and pass the required XML as an argument instead of an object? I can get this to work: $oClient = new SoapClient( $sWSDL_URI, array( 'trace' => TRUE, 'exceptions'=> TRUE ); $oArgObj = new ArgObj(); $oArgObj->node1 = 'value' $oArgObj->node2 = 'value' $oArgObj->node3 = 'value' $oClient->doMyAction( $oArgObj ); but not this: $oClient = new SoapClient( $sWSDL_URI, array( 'trace' => TRUE, 'exceptions'=> TRUE ); $sXML = 'valuevaluevalue'; Which, if I look at the result from __getLastRequest(), is exactly what the XML sent looks like (minus the SOAP body, etc). The error I keep gettings is "xml-resolve-missing-var-error". Is there any way I can just send the XML? Or does it have to be an object with the appropriate properties set? thnx, Chris -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Static method variable
Perhaps I'm misunderstanding what a static method variable is supposed
to do. I thought the value would be static for an class' instance but
it appears it is static across all instances of the class. Consider:
class StaticTest
{
public function __construct()
{
}
public function test( $newVal )
{
static $retval = '';
if( $retval == '' )
{
$retval = $newVal;
}
echo $retval . '';
}
}
$one = new StaticTest();
$one->test( 'joe' );
$two = new StaticTest();
$two->test( 'bob' );
Should it be working that way?
thnx,
Chris

[PHP] Singletons
Ok, so why isn't this working as (I, at the very least) expected?
class singleTon
{
private static $thisObj = NULL;
private $thisProp = NULL;
public function __construct()
{
echo 'singleTon::__construct()';
if( !is_null( singleTon::$thisObj ))
{
echo '$thisObj already set. returning it...';
return singleTon::$thisObj;
}
singleTon::$thisObj = $this;
}
public static function singleton()
{
echo 'singleTon::singleton()';
if( is_null( singleTon::$thisObj ))
{
$retval = new singleTon();
}
return singleTon::$thisObj;
}
public function setThisProp( $sVal )
{
$this->thisProp = $sVal;
}
public function getThisProp()
{
return $this->thisProp;
}
}
$one = singleTon::singleton();
$one->setThisProp( 'Joe' );
echo '$one->getThisProp();: [' . $one->getThisProp() . ']';
echo '$one: [' . var_export( $one, TRUE ) . ']';
$two = new singleTon();
echo '$two->getThisProp();: [' . $two->getThisProp() . ']';
$two->setThisProp( 'Bob' );
echo '$two: [' . var_export( $two, TRUE ) . ']';
echo '$one->getThisProp();: [' . $one->getThisProp() . ']';
echo '$two->getThisProp();: [' . $two->getThisProp() . ']';
echo '$one->getThisProp();: [' . $one->getThisProp() . ']';
I would have thought that both $one and $two would be referencing the
same object but they aren't. Apart from making the constructor
private, is there any way I can ensure that there is ever only one
instance of an object?
thnx,
Christoph

Adding the above to my sample class (from my OP) did nothing. Should it have?

Re: [PHP] Singletons

The problem being if the class in question derives from another class
that has a public constructor... If you are in that particular
situation (which I am), you're basically SOL and the statement above
has no bearing.
>> {

I did this mainly to see if it would have any effect.

It has no effect. And yes, that is true in general, but this is just
a test foobar class.

This won't work if derived from a class with a public constructor.
That's why my test class' constructor was defined public.

Agreed. But apparently implementing them in PHP leaves things to be desired.

What makes you think that a singleton > class has to inherit from another class? Nothing at all. Except that in my particular case, I do need to inherit from another class which has a public constructor. And the class I'm trying to write needs to be a singleton. I guess that teaches me not to post a question without including a doctoral thesis about what it is I'm trying to do. I figured just including the most base and/or basic parts of what I was dealing with would be sufficient. Though, I will say I probably shouldn't have included all of that junk in the constructor in my OP. That was just a hail-mary-pray-it-might-be-a-workable-workround on my part.

Except that in one of my follow up posts I indicated that my singleton
class was deriving from a class that had a public constructor.
Thanks anyway. I ended up just using Stut's suggestion. As he said,
it's not pretty but it is simple.

Re: [PHP] class constructor overloading

No, it's not.
> class A
> {
>function __construct()
>{
>echo "A";

The above is an example of overriding, not overloading; PHP allows the
former but not the latter.
Examples of overloading include:
class A
{
function myFunc( $boolean )
{
}
function myFunc( $string )
{
}
function myFunc( $array )
{
}
}
Because PHP is loosely typed, the above is largely moot/unnecessary.
class B
{
function myFunc( $boolean )
{
}
function myFunc( $boolean, $string )
{
}
function myFunc( $boolean, $string, $array )
{
}
}
PHP allows you to get around the above by allowing you to define
default values for arguments. Doing that is kind of like overloading
but only in a fake-me-out kind of way. So instead of overloading the
myFunc method, you could just define it as follows:
class B
{
function myFunc( $boolean = FALSE, $string = '', $array = array())
{
}
}
but even that doesn't ensure that the data type of each argument is as
you might expect. As I stated above, PHP is loosely typed so there is
nothing preventing, say, the $string argument from actually being a
numeric datatype. If you are using PHP5+, you can sort of get around
that by using type hinting
(http://us.php.net/manual/en/language.oop5.typehinting.php) but you
can only type hint objects and arrays.
In closing, to answer your question,
Overriding: yes
Overloading: no
thnx,
Chris
