[PHP] Re: Two very useful PHP functions
'Twas brillig, and Raymond Irving at 30/04/09 03:32 did gyre and gimble: Hello, Every so often I have to be using the isset() function to check if a variable exists. It would be useful to have something like an ifset() function Instead of doing this $v = isset($input) ? $input : $default; we can do this $v = ifset($input,$default); // returns $input if it exists otherwise it will return $default We could also do the same for the empty() function. So instead of doing this $v = empty($input) ? $default : $input; we can do this $v = ifempty($input,$default); // returns $input if it is not empty otherwise it will return $default What do you think? Can they make it into 5.3? To be honest, I don't see the compelling need for this. I don't disagree that the functionality is nice, however I quite like the verbose versions as they are clearer to understand without knowing an API function. Also, most of the cases that you would use these functions are with input from GET args and the like. Most frameworks provides wrappers for this with handy ways to get the defaults etc. So overall, I can't see this becoming a core PHP feature.

[PHP] Getting Sub Elements with XPath
Hi all,
I have the following XML returned to us.
We need to get the values of the FromDay, ToDay and ChargeAmount from the
following sub elements:
I hve the following code: But I am not able to get the second element's
details: (Charge: false, FromDay: 1)
$Elements = $xpath->query(
'ResponseDetails/SearchChargeConditionsResponse/ChargeConditions/ChargeCondition/',
$responseElement );
foreach( $Elements as $Element )
{
$itemStatus =
$xpath->query('Condition/Charge' , $Element);
$FromDay2 =
$xpath->query('Condition/FromDay' , $Element);
$condition =
trim($itemStatus->item(0)->textContent);
echo "CONDITION: #" .
$condition."#";
$FromDay =
trim($FromDay2->item(0)->textContent);
echo " FromDay: " . $FromDay;
if ($condition =="true")
{
$ChargeAmount2 =
$xpath->query('Condition/@ChargeAmount' , $Element);
$ChargeAmount =
trim($ChargeAmount2->item(0)->textContent);
echo " CHARGE AMT: " .
$ChargeAmount;
$ToDay =
$xpath->query('Condition/@ToDay' , $Element);
$ToDay =
trim($ToDay->item(0)->textContent);
echo " ToDay: " . $ToDay;
}
else if($condition =="false")
{
$FromDay2 =
$xpath->query('Condition/@FromDay' , $Element);
$FromDay =
trim($FromDay2->item(0)->textContent);
echo " FromDay: " . $FromDay;
}
}
It apprears that I need to add a further loop through the "ChargeCondition"
elements, IE
change
$Elements = $xpath->query(
'ResponseDetails/SearchChargeConditionsResponse/ChargeConditions/ChargeCondition/',
$responseElement );
to
$Elements = $xpath->query(
'ResponseDetails/SearchChargeConditionsResponse/ChargeConditions/',
$responseElement );
Then I can test the type if its "cancellation" and loop through the
subelements (Condition)
Would this appear to be correct?
Anything else that would appear to be incorrect from the above code for the
accompanying structure?
thanks

The only data you need from table product is the column prod_cat0, from
table categories it's category, so you should read only the needed data
instead of using * for better performance.
Take the SQL and verify if it returns what you want it to return then.

[PHP] Renaming archive entries doesnt work
Hi,
I am trying to add a prefix to all of the entries in a zip file using
the ZipArchive::renameIndex function which is corrupting the files
when I try to extract them. I was wondering if anyone else has used
this method successfully? Here is the code im using:
$client='TEST';
$zip = new ZipArchive();
if ($zip->open($targetpath,ZIPARCHIVE::OVERWRITE)===true)
{
// prefix all of the files with the clients name
for($i = 0; $i < $zip->numFiles; $i++)
{
$zip->renameIndex($i,$client.$zip->getNameIndex($i));
}
if (!$zip->close()) echo 'Failed to rename zip';
}else echo'Failed to open zip';
This renames the files inside the zip but when I try and extract them
the zip is corrupt.

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;
thnx,

You might be able to cut down your code further with something like this:
query(
"ResponseDetails/SearchChargeConditionsResponse/ChargeConditions/chargeconditi...@type='cancellation']/Condition",
$responseElement );
foreach( $Elements as $Element )
{
$condition = $Element->getAttribute('Charge');
$FromDay = $Element->getAttribute('FromDay');
echo "CONDITION: #" . $condition."#";
echo " FromDay: " . $FromDay;
if ($condition =="true")
{
$ChargeAmount = $Element->getAttribute('ChargeAmount');
echo " CHARGE AMT: " . $ChargeAmount;
$ToDay = $Element->getAttribute('ToDay');
echo " ToDay: " . $ToDay;
}
else if($condition =="false")
{
echo " FromDay: " . $FromDay;
}
}
?>
I'm not sure if you really want it to print FromDay twice in the case
that Charge == 'false', but you should be able to sort that out.

Re: [PHP] Warning: Division by zero
Thanks for your response.
The error I am getting is when I am defining a variable.

Does this make a difference?

The simple fact is that $assess_value is either undefined or has been set to 0 at some point. For it's use in the above equation, neither case is valid. Consequently, you really should be doing some validation at some point prior to that line. thnx, Christoph -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

If you're just capturing and using the body, the load with
file_get_contents() and use preg_match() to select the body or
individual tags, etc... For more control, maybe try this:
$doc = new DOMDocument();
$doc->loadHTMLFile('http://example.com/page.html');
Then use: http://php.net/manual/book.dom.php

[PHP] $this = new Class();
Hi all,
Since I can't do $this = new Class(); within my class (it gives an
error), I was looking for ways to get the same result by other means.
I am actually working on an ORM and trying to implement lazy loading.
$book = $orm->getBook('id'); // returns an Orm object
$book->load();
// $book should now be a Book instead instead of an Orm instance
Of course, I oversimplified the problem. $book = $orm->getBook('id');
doesn't return a Book instance right ahead because it is a chained
method (i.e. $orm->getBook()->where(...)->prefetch(...)->etc
Therefore, it _has_ to return an Orm instance.
Now, why not simply add ->load() at the end of the chain? Because it
adds an extra step for developers that doesn't bring meaningful
information. Instead of doing $book = $orm->getBook('id');, it would
mean having to do $book = $orm->getBook('id')->load(); (which is
longer to type :p). That's why I wanted to implement "lazy loading".
$book = $dorm->getBook('id');
echo $book->title; // title should be trapped by __set() and it should
dynamically replace $book by an actual Book instance
I tried doing the following, but PHP doesn't allow it:
class A {
public function transform() {
$this = new B();
}
}
class B {}
$var = new A();
$var->transform();
This is not currently supported by PHP and I was wondering if there
was anyway of getting around the problem, that doesn't involve
1) passing $var to the A class i.e:$var->var = $var;
2) looping $GLOBALS[]
3) using __call,__get and __set to proxy everything to the actual Book object
PS1: don't lecture me about how I'm doing this all wrong. I've looked
at the problem from every possible angle and this is the only
solution.
PS2: Another alternative would be to subclass the Orm object with
Book, (class Orm extends Book {}), overload all properties/methods so
we can catch when to load the object... but that would be an extreme
pain in the ass.
PS3: Another alternative would be to have a parameter that
enables/disables chaining.
$dorm->getBook('id', true); // chain (you now have to add ->load() at
the end of the chain)
$dorm->getBook('id', false); // dont chain, this returns a Book instance
The point of all this is to keep the most friendly interface !
Cheers,
Olivier

I tend to do my loops like this:
while ($col2 = mysql_fetch_array($result))
{
$id = $col2["category"];
$selected =($id == $catquery['prod_cat0'])?'selected="selected"':'';
$catlist1 .= "$id";

Just looks a little neater. 'Course, you could remove the $id line and
chuck the value straight into the short if statement there.

It'd be a hassle to just remove a function from a language, I suppose...

[PHP] Bhups on the go for a Charity Walk! - Any support appreciated.
Hello! I'm taking part in the ISSO Seva Charity Walk 2009 on 19/07/2009 to raise money for International Swaminarayan Satsang Organisation and I'd really appreciate your support. It's easy to sponsor me online by credit or debit card - just go to my Justgiving page: http://www.justgiving.com/bhupspatel Justgiving sends your donation straight to International Swaminarayan Satsang Organisation and automatically reclaims Gift Aid if you're a UK taxpayer, so your donation is worth even more. I hope you'll join me in supporting International Swaminarayan Satsang Organisation. Thank you. Bhupendra P.S. I used Justgiving to send this email, so please don't reply to it. Replies will go to Justgiving, not to me! -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Was I mistaken? yes. see http://www.w3.org/TR/html401/charset.html which says that html uses the UCS, a character-by-character equivalent to the Unicode character set. so if you use a unicode character encoding (such as utf-8) then you you have a direct encoding for every unicode character in html. so a utf-8 html file or stream should normally to have no entities other than <, >, $amp; and perhaps " as needed. texts file may be utf-8 encoded too. xml, json and csv files are more examples of text files that can be utf-8 encoded and use any unicode character simply and directly. windows and os-x have used utf-8 as their default text file encoding for many years now. > http://www.cl.cam.ac.uk/~mgk25/ucs/examples/UTF-8-demo.txt > > That is supposed to be a UTF-8 encoded text file, between 1/3 and 1/2 > of the characters do not display correctly on my screen. this page looks great to me. i don't appear to have the runes or amharic fonts on my computer so those aren't showing but everything else works. why this doesn't work for you is not clear. it could be that your browser has a preference configured to override the charset specified in the http headers. or perhaps the browser does not observe the specified content type for txt files. > Either way, > this next link suggests that Turkish characters with no equivalent in > the English language should be encoded for Web display: > > http://webdesign.about.com/od/localization/l/blhtmlcodes-tr.htm don't believe everything you read on the web. while some browsers may tolerate it, i don't think pages encoded according to those suggestions would even be valid html. > And because that is off-topic, I'll throw this in: > > The consensus seems to be that the proposed "ifset()" and "ifempty()" > functions are more effort than they are worth.

Re: [PHP] utf-8 ?
The consensus seems to be that the proposed "ifset()" and "ifempty()"
functions are more effort than they are worth. What I'd like to know
is, why "empty()" still exists when every time I turn around, the
mentors I turn to locally tell me not to use it, to use "isset()"
instead. Because empty() doesn't work with zero. Anyone care to take
a stab at that?
They serve different purposes and both work very well.
$form_errors = array();
// process form
foreach (array('name', 'email') as $field) {
# Hey! someone hacked the form! This field is supposed to be there!
if (!isset($_POST[$field])) {
$form_errors[] = 'Field ' . $field . ' was missing';
continue;
}
# The field is there but has no value.
if (empty($_POST[$field])) {
$form_errors[] = 'Field ' . $field . ' was empty';
}
}
if (!empty($form_errors)) {
echo 'there were errors in processing the form.';
exit;
}

[PHP] Eclipse, PDT plugins for hosting, scaling and managing PHP apps.
re: Eclipse, PDT plugins for hosting, scaling and managing PHP apps. Aptana has released a new suite of tools for PHP developers that extends the popular Eclipse PDT environment. The plugin for Eclipse, called Aptana Cloud Connect, lets you get all the benefits of scalable, on-demand PHP hosting in the Cloud with the ease of integration right into Eclipse and PDT (You can plug it into Zend Studio as well). A few clicks is all that's needed to get a running PHP, MySQL, Apache environment running in about one minute. Then the plugin lets you instantly scale your web and database servers in the Cloud up or down anytime. There's a very useful set of visual database tools for working with your remote database. For file transfers, there's a "Smart Sync" utility that help you keep local projects coordinated with the remote sites. You can do single file uploads/download and edits as well. Try it out by adding Aptana Cloud Connect to your Eclipse 3.4 PDT installation.

Re: [PHP] DateInterval
Ah. This makes perfect sense. Good idea. Mike Raymond Irving wrote: --- On Wed, 4/29/09, MIke Alaimo wrote: Raymond, have you tried using DateTime::modify? It appears to work like strtotime. also DateTime::format works like date. At least as far as I can tell. From the little documentation that I've seen it appears that it's similar to strtotime and date but it would be very good if the PHP devs could make strtotime() and date() become wrappers for DateTime::modify and DateTime::format. This way we dont hae to modify our code when moving to a version of PHP that supports the new DateTime class. __ Raymond Irving -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Two very useful PHP functions
Hi Colin and Daniel, Thanks for the feedback. I know that this functionality can be added to a framework or a stand alone function but I'm assuming that we would not get the same performance: Case 1 --- $c = isset($a) ? $a : ''; // total time = overhead of isset() + overhead of ?: Case 2 --- $c = myWrapper($a,$b) // total time = overhead of myWrapper() + overhead of isset() + overhead of ?: Case 3 --- $c = ifset($a,$b) // total time = overhead of ifset() Best regards __ Raymond Irving --- On Thu, 4/30/09, Daniel Brown wrote: > From: Daniel Brown > Subject: Re: [PHP] Two very useful PHP functions > To: "Raymond Irving" > Cc: php-general@lists.php.net > Date: Thursday, April 30, 2009, 11:37 AM > On Wed, Apr 29, 2009 at 22:32, > Raymond Irving > wrote: > > > > What do you think?

[PHP] ImageMagick
Here's the scenario - Website has some demonstrative images. I create these images with the gimp - starting with a jpeg, adding a few text layers and straight lines. I then save as xcf in case I ever need to edit. Then I export to jpeg, resize for thumb and export to jpeg again. Admin interface to my web face needs to allow for upload of image. What would be sweet is if I could just upload the gimp xcf in these cases, and have ImageMagick do the export to jpeg and thumbnail creation. Advantage of doing it this way - it will allow me to keep the original xcf on the server along with the generated images. Issues - I'd rather not have any code that spawns a shell, so I can only do this if the pecl imageMagick module is up to snuff for xcf->jpeg conversion. Anyone used it? Looks like I'll have to compile it, before I do that I would like to know if it even is up to the task. Second possible issue - I don't know how well imageMagick can deal with an xcf file that uses text layer / fonts. I assume I'll have to install the font used on the server (Adobe New Century Schoolbook Type 1 - yes, I have license for it), but if so, how would I specify to ImageMagick the font path? Anyone done this sort of thing? I may just do the export on my home box via gimp and just scp the xcf to the server so a copy is stored there as well, but it would be nice to just stick the xcf into a file upload field and just have php do the rest. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

If not, you can add t existing images with GD, by using a source image, adding text layers, etc, and then exporting it as a new graphic.
