[PHP] Strange error in PHP 4.3.4RC2
Hi, I am experiencing a strange error while using PHP 4.3.4RC2. In the apache2 log, I read: fatal: cannot realloc() 1937201923 bytes. I do NEVER try to allocate such memory. I think the problem is related to some serialize/unserialize() code I am using (in fact, removing serialize/unserialize block makes the script work perfectly). Is there anything I can do to test _exactly_ where the script bombs? Ciao, Fabio -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I'm having a bit of difficulty getting a string to attach to itself from an
array. Here is the bit of code I'm working on.
$wresult = ;
foreach ($search_string as $word_result){
$wresult = $wresult $word_result;
}
what about:
$wresult = join ( , $search_string );
Ciao,

[PHP] Strange problem in class creation
Hi all,
I have encountered a tricky problem with PHP 4.3.1 (installed with
SuSE 8.2).
I don't know if it is a bug or not. Maybe is just me missing something.
What I'd like to do is to pass a reference of base_class instance to the
constructor of second_class (so that the newly created second_class
instance can
call methods from the base_class instance.
It seems that if base_class constructor directly calls its method
create() (that is
responsible of creating the second_class instance, passing _$this_ as
constructor
argument) the second_class gets a copy of base_class instance and
not the real thing.
To test it, I have added an array ($arr) in the base_class and set a
value into it.
If second_class really have a reference to the real base_class
instance, it should be
able to print its contents, but this just doesn't work.
Please, notice that if in the following code you remove the line
$this-create()
in the base_class constructor and add the commented line in the main
body, everything
works fine.
What I am really missing?
Please, help!
Ciao,
Fabio
CODE STARTS HERE --
?php
class base_class
{
var $arr;
var $class;
function base_class ()
{
$this-arr = array ();
$this-class = false;
// it seems to create another instance of base_class
$this-create (); // this line does not work
}
function set ( $val )
{
$this-arr [] = $val;
}
function create ()
{
$this-class = new second_class ( $this );
}
function test ()
{
$this-class-dump ();
}
}
class second_class
{
function second_class ( $main_class )
{
$this-main_class = $main_class;
}
function dump ()
{
print_r ( $this-main_class-arr );
}
}
$b = new base_class ();
// $b-create (); // This line works as expected
$b-set ( ciao );
$b-test ();
print br /;
print_r ( $b-arr );
?
END CODE -

Re: [PHP] Strange problem in class creation
Mukul Sabharwal wrote: And the error is strange because you're doing something strange! I don't think I'm doing anything strange. What I have exposed here is a simplification of my own class loader. I have the main class that must load (include and then instance) other PHP classes. The problem is that if I do instance other classes in the loader constructor they get a copy of the loader instance and not the real instance reference. [some your code snipped] $base = new base_class; $second = new second_class($base); $second-foo-some = 100; // here it is, base_class' some is accessible I know. If you give a closer look to my own code, you'll see that there is a line (commented) doing almost the same thing as you. But I need something else. Infact, look at the end of my code, there are these two lines: $b = new base_class (); // $b-create (); // This line works if I instance the base_class and outside the constructor i do the create (as shown in the second line) everything works. And I am actually just sending ($this) as the argument (look inside the create method code), in exactly the same way I was doing in the base_class constructor. The problem is that inside the constructur THE SAME CODE DOES NOT WORK. I think it's a bug. I have worked around it by doing the two calls, but I would like to know if it is a real bug or just me doing something wrong.

[PHP] Re: Cannot add header information - headers already sent

You already have had the right answer, but I think you could consider adding this line at the top of your PHP script: ob_start( ob_gzhandler ); this enables HTML compression (on browsers that support it) and allows a much more flexible headers handling because text is sent back to the browser when your page is complete.
