php-gtk Not enough storage is available to process this command

[cwarn23]

Hi and I have the below php-gtk script but for some reason it is reporting the error "Not enough storage is available to process this command." in the command console but the application still loads. It only happens when I try to import a 1.75MB text file for processing. Does anybody know why regex and str replace on a 1.75MB file causes this error or how to increase its storage. Please advice.

<?php
ini_set('memory_limit','256M');
if (!class_exists('gtk')) {
    die("Please load the php-gtk2 module in your php.ini\r\n");
}

//reword button clicked.
return true;
}

Found the problem. The following line is the bug.

$textareaBuffer->set_text($text);

The buffer can't hold more than 1024 characters. Does anybody know how to insert more?

Solved. Downloaded the latest version of php-gtk and the bug is fixed.
