[PHP] Why don't webhosts upgrade to PHP5 ?
My webhost doesn't want to upgrade to PHP5 because of security reasons and some scripts that will mallfunction. I find it hard to believe. Current conf of webhost is PHP 4.3.11, Apache 1.3.33 and MySQL 3.23.49. What real reasons could there be not to upgrade ? How could I convince them to upgrade to PHP5 ? (Less important for me : but why not upgrade to Apache 2.x and at least MySQL 4.x ?)

[PHP] Security question
Hi list I've got a concern for a user add/edit form. Right now when the user is logged in, I put its id in the session. Then when the user edits his details I put the id in the form and when it comes back I verify if the id matches the one in the session. Is it possible for someone who does not have access to the server to edit arbitary accounts? With kind regards Andy -- Now listening to Top!

Current upgrade to php5 == "scripts that will mallfunction" == support calls == losing money. thats how I see the ISPs view of upgrading to php5, regardless of whether they are right for them it seems to be a simple matter of economics and operational stability. you also have to consider the ammount of work involved is purely performing the upgrade properly. conf of webhost is PHP 4.3.11, Apache 1.3.33 and MySQL 3.23.49.

PHP 5 *WILL* break some scripts, and most big suits like forums and shops and stuff will need a serious amount of work to convert to php 5 and some scripts are broken. there is a lot of code out there that is technically evil (potential segfaults etc) so this cuts boths ways. besides most apps [forums etc] out there arn't hard at all to convert - the problem for the developers of such apps is more likely to be about releasing versions that run on both (which is more difficult) or maintaining 2 releases, which eat into your time. Same applies for Apache and MySQL. Consider this, NASA still uses 386 cpu's in their space equipment because they are a lot more stable and mission secure then newer chipsets. are you sure its not because they have invested so much time and energy into the hardware, software and procedures surrounding the cpus. refitting a space shuttle is not done on a whim like your changing the cpu in the box under your desk... comparitive stability wirth newer models doesn't factor in at all if you consider that every part on a space shuttle could be assumed to only be authorized for use after it's absolute stability has been proven.

RE: [PHP] What software do you use for writing PHP?
Nusphere PhpED and love it. Tried a few other editors but stayed with PhpED now for the last year and about to renew my subscription. Excellent project management, brilliant debugger (local and remote), code error detection and highlighting, fast (much faster than the java editors), able to handle huge projects, and very stable. Not as expensive as the Zend equivalent (last time I checked) and in my opinion it's better. Good support from the forum and quick responses from the support desk. I keep checking out the new editors and new versions of old editors as they come out but nothing yet to match PhpED. I develop on Windows but there's a Linux version too (which I haven't tried).

Hi,
I scoping out an Internet site project and my primary consideration at

about something like the pseudocode at the bottom of this message

Can PHP do this sort of thing? I'm wondering if there are some classes
available to do this? I don't think I want to use WWW-Authenticate (at
least I don't want to use the ugly password dialog) and I certainly don't
want to authenticate via pam or something like that. I want "as simple

to bloatware.
Or am I off track? I normally do pretty low level C type stuff so websites

session and request are not objects in php (you could create userland wrapper
objects for them though), string concatenation is done with a '.',
variables are prefixed with '$', you don't have to declare variable types, etc.

It works fine if I add just one line outside of the loop but as soon as

Title: Re: [PHP] PHP Warning: imagettftext() expects parameter 2 to be double
Hi,
Thank you for getting back to me, your the first.
The array works fine – I have tested it using var_dump().
Attached are the two files – xml.test – this holds the array of the text blocks which is being parsed by image.php.
Line 38 is the problem, if you comment around the foreach() statement and un-comment the commented lines you should see it working fine, its when its within the foreach statement when it errors.

James

PS.
Yeah, thought it was libxml, hence didn't file a pecl bug report. But
there does seem a problem with this method as can't
just have a publicId or a systemId, libxml function uses NULL as a parameter to
specify which id you don't want to use. Which we've
lost with the PHP wrapper, as can only specify two strings.
And when pecl.php.net was reachable I'll report it.

this time, it is updateting only one row.
I tried to use "LOCK TABLE table IN ROW SHARE MODE;LOCK TABLE table IN ROW

How can I lock all rows, any advice ?

Re: [PHP] FW: Advanced search form
Here is some code that you can modify. It's design to convert a
search string into a MySQL full text search string, not sure how
different pgsql is. It adds * for word expansion where appropriate.
It assume a space is the delimiter, but that's easy to change in the
explode statement.
Example:
"this is a search" -XXX Test
becomes
+"this is a search" -XXX* +Test*
Conversion function:
function prepFullTextSearch($searchVal) {
//Split words into list
$word_List = explode('
',stripslashes(trim($searchVal)));
//Step through word list to get search phrases
$i = 0;
$isPhrase = false;
foreach($word_List as $word) {
$searchItems[$i] = trim(($isPhrase?$searchItems[$i].' '.$word:
$word));
//Check for start of Phrase
if(substr($searchItems[$i],0,1) == '"') {
$isPhrase = true;
}
//If not building a phrase, append wildcard (*) to end
of word
if(!$isPhrase) {
$searchItems[$i].= '*';
$i++;
}
//Check for end of Phrase
if(substr($searchItems[$i],-1) == '"') {
$isPhrase = false;
$i++;
}
}
$searchVal = '+'.implode('
+',$searchItems);
$searchVal =
str_replace('+-','-',$searchVal);
return $searchVal;
}

Hello PHP-Gurus,
I have already ask this on php-de and pgsql-pgp but unfortunatly
gotten no answer.
I have a search form and I like to add advanced search options like
"this is a search" -XXX Test
which mean,
1) "this is a search" must be in this order
2) -XXXDo not find XXX contents
3) TestAND
Does anyone has a PHP/PGSQL code sniplet?
Thanks

[PHP] Class Constant PHP 5
is there a way to dynamically define a class constant during runtime
in PHP 5?
for example I would like to achieve the result of something like:
class Example {
const FOO = bar();
}
However this would obviously give a parse error.
I know it is possible with variables but I would like it to be a
constant.
Thanks.

Re: [PHP] Class Constant PHP 5
Dynamically setting a constant would break the very rule of it being a
constant in the first place.
a constant is something that does not change it cannot be dynamic.

Well, first of all the syntax you describe above does not define a constant
at all, you would need to use define()
The second thing is good old basic OOP theory, you should declare a private
static variable
http://us3.php.net/private
http://us3.php.net/manual/en/language.oop5.static.php
Of course you could define a global constant and then pass it into your
object when instantiating it, but that is a bad idea generally.
Thirdly, you could never use a function to derive your constant value...it
would then be an oxymoron. If the value generated by the function bar()
changes, FOO is a variable. Constants are for simple values. For instance,
we can all agree that pi is 3.14159 (to 5 decimal places, so defining a
constant pi makes sense;
define("PI", 3.14159);
If we do not know what the outcome of a function will be it makes the value
of the outcome a variable, always. It would be foolish (and would fail
anyhow) to do something like this;
define("RANDOM", rand(5,12));

Wow, that should fail. But you did have use var_dump() to get it, which may
be slightly counter-intuitive. I just did this

$x = $x * rand(5,10);
return $x;
}

There's been a lot of great articles in the PHP|Architect magazine over
the past 3 months or so about this (http://www.phparch.com) You do have
to purchase back-issues though. Very good articles though. They cover
how to make functions to filter what variables should be sent in, and
how to make sure all the data is what you expect.

Re: [PHP] Class Constant PHP 5
The point was more that the constant's value is 'defined' at the
beginning of the script, and is constant and non changing throughout
the entire execution of the script. But I was looking for a way to give
it a namespace inside a class rather than just defining in in the
global scope so that I do not have to worry about conflicting names
with other packages such as PEAR et al.
I wanted to do something like:
so that I I could later use the notation
$value = ClassName::ConstantName
or from within the class
$value = self::ConstantName
and ensure other developers could not change the value of the constant.
To achieve the result I want I could do:
But that just seems pointless and messy. I will assume that the simple
answer to my original question was 'No that it is not possible'.

Well, first of all the syntax you describe above does not define a

at all, you would need to use define()
The second thing is good old basic OOP theory, you should declare a
private
static variable

http://us3.php.net/manual/en/language.oop5.static.php
Of course you could define a global constant and then pass it into your
object when instantiating it, but that is a bad idea generally.
Thirdly, you could never use a function to derive your constant
value...it
would then be an oxymoron. If the value generated by the function bar()
changes, FOO is a variable. Constants are for simple values. For
instance,
we can all agree that pi is 3.14159 (to 5 decimal places, so defining a
constant pi makes sense;
define("PI", 3.14159);
If we do not know what the outcome of a function will be it makes the
value
of the outcome a variable, always. It would be foolish (and would fail
anyhow) to do something like this;
define("RANDOM", rand(5,12));

curious to see what would happen if you took out the pass-by-

Then again, that doesn't particularly sound correct either.

http://aspn.activestate.com/ASPN/Mail/Message/php-Dev/1555640
(so maybe this question belongs on php-dev but I figured I'd try
here first... seems like a userland question)
Basically I have an object model to represent db objects, and I
am bulk-loading the objects via some PHP scripts. Sadly the
scripts consume unbounded memory because of this problem.
I have done a lot of programming in C++ and Obj-C and the normal
way to handle circular references is to have parents
"retain" (keep ref- counted links) to their kids, and have the
kids have "weak references" (non-ref-counted) links to their
parents. This way, when the parent is no longer used, it will
automatically 0-out the ref counts to all children it links too
and things GC correctly.
Now, how to do this in PHP?
Well, there are no "documented" weak references. However, I
figured out by trial that if you obtain a php-reference to an
object, it doesn't bump the refcount.
Question #1: Is the fact that references to objects in the form
$objRef = &$obj don't bump the refcount of $obj an intended
behavior that can be counted on? If so, cool!
So, now that we have a way to do weak references, we should be

parent-child objects.
Normally from the client side the interface should look something
like:
$parent = new Parent();
$child = new Child();
$parent->addChild($child);
Where parent can have 0,n children and child can have 0,1 parent.
And all of parent's internal links to child should be refcounted,
and the internal links from child to parent are weak (not ref-
counted).

My original statement was to show how the the php4 = &$o is

Oh, well, sure I believe that! :)
In php5 variables are just containers that point to objects, so
when you make
a variable a reference to another variable all you are doing is
saying these variables are the same thing.
That's good to know... one thing that's difficult about PHP is that
everything's opaque and not well documented. In C/C++ I know what
things actually are b/c you can see the typedefs. In php I just don't
know how objects are represented, what references are, etc.
So, knowing that an "object" variable is really just a "special
container object" that points to the real instance, this is useful.
That isn't clear from the php docs. Thanks!
php5's objects dont know any such thing as a reference, they just
know of instances of themselves. The variables ($o, $a, $b)
existance is just a container for the instance of the object. So in
the case when I do a:
$b = &$o;
All that is happening is the container is identical, so when I say:
$o = null;
Since $b is the same thing as $o , $b is set to null as well and
thus, there are now more variable (containers) that reference to
the instance of the object, thus the object will get destroyed,
but.. if i say we have two containers:
$o = new stcClass;
$b = $o;
Now the instance of that 'new StdClass' is contained in two vars,
when I set $o to null, $b still exists since it doesn't know about
$o whats so ever, and the instance of the stdClass still exists.
Yes, this makes sense, too. It's tricky, with so many levels of
indirection. So at the core level, you've got the "real" object
instance. Then, you've got N container "object variables" that point
to the real instance. PHP refcounts the number of object variables
pointing at the real instance. Then, on top of that, you have
references, which are "aliases" to "object variables" and thus don't
affect the ref count. So good this all makes sense and agrees with
the behavior I see.
I guess it comes down to objects are treated the same way as you
would expect these results:
Yes...
The sample code below shows that indeed, in practice, on 5.0.4, that
& will create another reference (ie a weak reference) to an object
WITHOUT incrementing the refcount
I'm not sure how you mean a weak reference, and well a refcount is
rather meaning less in php userland.
So, this gets interesting. I don't know if you're familiar with the
circular-reference problem. But if you have two instances that have
references to each other, even once you remove all references to the
objects, they will not be GC'd since they have a mutual deadlock on
each other:
$a = new MyObj;
$b = new MyObj;
$a->setB($b);// does $this->b = $b;
$b->setA($a);// does $this->a = $a;
$a = NULL;
$b = NULL;
The actual instances pointed to by $a and $b WILL NOT GET FREED HERE
as you would *wish*. However this is expected behavior.
Only by changing MyObj to store "weak references", that is references
to the objects that are NOT reference-counted, can you get the GC to
free the instances.
function setB(&$B) { $this->b = &$a; }
function setA(&$B) { $this->a = &$b; }
Now, the instances will be freed when the $a and $b are null'd out.
So, while I now feel more confident of how references act with
respect to objects (which is, they act the same as they do for any
variable), I still am not sure what "$this->this" is and why it
worked so magically.
Thanks for the explanations! I feel better about this now.

Re: [PHP] ob_start & session_start
Sure, ob_start begins a buffer allowing you to display content in the browser before your script has finished executing. This is useful when loading a time intensive page to tell the user to wait. When you create a session (provide php is not configured otherwise) php attempts to store a cookie with the session id that corisponds to the session file on the server. If it cannot set this cookie it appends the session id to pages in the get format. If you were to call session_start() after the output buffering, content and consequentially the headers would have been already sent to the browser. Since cookies must be set in the headers and the headers must be set before any content is sent to the page, to use cookie based sessions you must begin the session before the buffer.

Re: [PHP] ob_start & session_start
I guess this was just out of general curiousity... If you started 'session_start()' after 'ob_start()' would the sessions work correctly? k.. maybe I am still confused... lol... I normally do session_start() before the ob_start()... Zack Said : 'yes, it will display the content in the buffer before creating the session. If your session uses cookies (this is usually automatically decided by php) it cannot send out the header after the buffer.' So, the question is really... in what order is the best way to do this... I would think that you always want to start a session first... but then again, you guys are the experts... i am sure someone knows a reason when you should not do that. ;o) Joe On 12/8/05, Chris Shiflett <[EMAIL PROTECTED]> wrote: > Joe Harman wrote: > > Okay...makes sense after you spelled it out to me. > > That didn't make sense to me (and I missed the original reply).

The first thing I would ask is why are you using/need ob_start(). session_start() should be the first thing that happens in most cases. Since, well, any code that exist is potentially going to rely on a session state. If you are trying to use ob_start() to rid of the common error 'headers already sent in some_file.php on line such and such', i would first consider why that is causing the error and how can you call session_start() before that happens. Since '97 i think i've used ob_start twice, in all my php apps, and that was cause I wanted to filter the output either with tidy or modify the data in a very obscure way.

Re: [PHP] ob_start & session_start
Zack Bloom wrote:
Sure, ob_start begins a buffer allowing you to display content in

Calling ob_start() turns on PHP's output buffering. In other words, it
buffers output from the moment this function is called until the buffer
is flushed (whether explicitly or because the script finishes).
As long as PHP is buffering the output, the client can't get it.
This is useful when loading a time intensive page to tell the user
to wait.
I think you might be thinking of flush(), which flushes PHP's output
buffer as well as the output buffer of the web server (or whatever
backend PHP is using).
When you create a session (provide php is not configured otherwise)
php attempts to store a cookie with the session id that corisponds
to the session file on the server. If it cannot set this cookie it
appends the session id to pages in the get format.
Yeah, PHP includes a Set-Cookie header in its response. If
session.use_trans_sid is enabled, it will also rewrite URLs to include
the session identifier. When PHP receives a request that includes a
session identifier, it knows whether the client accepts cookies.
if (session identifier in cookie)
{
cookies enabled
}
elseif (session identifier in URL)
{
cookies disabled
}
else
{
new user
}
If you were to call session_start() after the output buffering,
content and consequentially the headers would have been already
sent to the browser.
Maybe you're getting the buffering and flushing concepts reversed? Think
of a toilet - buffering is the handle up, and flushing is the handle
down. :-)
Hope that helps!
Chris

I would have to disagree with the 'as you would *wish*' part.
if I pass something to a function/method via copy (vs reference) i
would hardly expect code outside the function/method to affect
their existance.

I think you meant to type:
function setB(&$a) { $this->b = &$a; }
function setA(&$b) { $this->a = &$b; }
And consider the definition written as:
function setB(&$a) { $this->b = $a; }
function setA(&$b) { $this->a = $b; }
does the $a = null; and $b = null; outside the class cause the
objects to get null'd inside the class as well?

You lost me on your $this->this statement.

Re: [PHP] array carrying from one php page to another
you could just pass in in the address, eg:
www.example.com?var1=$var1&var2=$var2
to get them use $_REQUEST['var1']
to pass an array you could use serialize($var1) and unserialize($var1)

Sorry it looked like the rest of your email was part of the previous one.
