PHP version: 5.0.4
PHP Bug Type: Scripting Engine problem
Bug description: Memory allocated for objects created in object methods is not
released
Description:
------------
Whenever you create an object in a method, memory is not released when the
method execution ends, unset() must be called manually.
This becomes a problem when you have long-running scripts, which perform
actions repeatedly which leads to the script running out of memory.
Reproduce code:
---------------
<?php
class Tester {
public function doNothing() {
$res = array();
for ( $i = 0; $i < 10000; $i++) {
$res[$i] = new StdClass;
}
}
}
$t = new Tester();
echo "Before: ".memory_get_usage()."\n";
$t->doNothing();
echo "After: ".memory_get_usage()."\n";
?>
Expected result:
----------------
Memory usage remains roughly the same.
Actual result:
--------------
Before: 41424
After: 432560
