PHP 4.0 Bug #8931: Memory leaks attributable to OO PHP

From: Jason@hspace.net Operating system: Windows 2000 PHP version: 4.0.4pl1 PHP Bug Type: Performance problem Bug description: Memory leaks attributable to OO PHP I wrote two scripts to compare the difference in performance between simple script and one written in OO with classes and required libraries. Both scripts accessed the SQL database using ADODB connection. I used Microsoft Web Application Stress Tool, which seems to be very useful. The "simple" version yielded better performance in less CPU usage (and no memory leaking), whereas the OO version maxed out the CPU usage 100%, as well as slowly but surely leaking memory. I tried using the unset() function in several places in the code, but this did not help much, as the script was still leaking memory during the tests. Using unset() to unset the COM object helped a lot, as PHP did not seem able to free the memory by itself. -- Edit Bug report at: http://bugs.php.net/?id=8931&edit=1
