Edit report at http://bugs.php.net/bug.php?id=26577&edit=1 ID: 26577 Updated by: jani@php.net Reported by: vijolicni dot oblak at gmx dot net Summary: [str_replace] Variable tracing 'optimization' causes 1.8GB memory usage -Status: Open +Status: Closed Type: Feature/Change Request -Package: Feature/Change Request +Package: *General Issues Operating System: Windows 2003 PHP Version: 4.3.4 -Assigned To: +Assigned To: jani Block user comment: N Private report: N New Comment: Should be fixed by now in PHP 5.x Previous Comments: ------------------------------------------------------------------------ [2003-12-10 10:35:58] sniper@php.net Apparently the win32 builds don't have 'MEMORY_LIMIT' defined. ------------------------------------------------------------------------ [2003-12-10 10:08:19] vijolicni dot oblak at gmx dot net W3WP.EXE (World Wide Web Worker Process) on Win2003 IIS6.0, while executing the script near max shows the following usage: Mem Usage:331.632K Peak Mem Usage:378.864K VM Size:794.532 Even if the bug is not in the PHP 'itself', there is a bug in improper interfacing between PHP and W3WP.EXE that causes W3WP.EXE to consume so much memory :) ------------------------------------------------------------------------ [2003-12-10 09:52:38] vijolicni dot oblak at gmx dot net Sniper! My php.ini has in it the following lines: ;;;;;;;;;;;;;;;;;;; ; Resource Limits ; ;;;;;;;;;;;;;;;;;;; max_execution_time = 30 ; Maximum execution time of each script, in seconds max_input_time = 60 ; Maximum amount of time each script may spend parsing request data memory_limit = 8M ; Maximum amount of memory a script may consume (8MB) >Sorry, but your problem does not imply a bug in PHP itself. ??? When I run the PHP script memory usage jumps to 1.8GB from around 400MB. Is it the Holy Ghost? >Thank you for your interest in PHP. ??? What does this mean? Should I switch to ASP.NET? >Your argument that PHP "should not do this or that" is flawed. This works just as expected. There are dozens of other ways too how you can "shoot yourself in the leg".. ??? What works just as expected? Try it on larger file. Should PHP render the computer useless by consuming more that 1GB? You don't even have to be a sniper to shoot it. BTW:The problem disappers with unsetting and setting back the variable... ------------------------------------------------------------------------ [2003-12-10 09:17:42] sniper@php.net See also: php.ini, memory_limit directive.. ------------------------------------------------------------------------ [2003-12-10 09:16:57] sniper@php.net Sorry, but your problem does not imply a bug in PHP itself. For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Thank you for your interest in PHP. Your argument that PHP "should not do this or that" is flawed. This works just as expected. There are dozens of other ways too how you can "shoot yourself in the leg".. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
