Previous Comments: ------------------------------------------------------------------------ [2014-01-01 08:36:11] krakjoe@php.net Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report. We require the inclusion of (by means of a link to some online hosting service for text files, ie git/pastebin etc) code that reproduces the error you experience. We have no way to guess the content of staticarray.php, and 3 arrays is not enough, obviously. If you are not able to include some data then generate some that exhibits the same symptoms, but generate it in such a way that it's as close to your use case as possible. ------------------------------------------------------------------------ [2013-12-31 08:42:42] nikcomestotalk at gmail dot com testscript has already been added Memcheck.php staticarray.php[Data is too huge, so adding few arrays to script][And i can't share the real data, some legal issues] <?php $siteType=array("API","MOBILE","WEB","ANDROIDAPP","IOSAPP"); $siteServer=array("127.0.0.1","127.0.0.2","127.0.0.3","127.0.0.4"); $country=array("INDIA","AUSTRALIA","UK","USA","CHINA","JAPAN"); ?> ------------------------------------------------------------------------ [2013-12-31 08:24:36] krakjoe@php.net Thank you for this bug report.

Steps i had taken to stop memory usage, but went in vain 1. use gc_enable 2. put unset(Variable name) above every array creation Test script: --------------- //Memcheck.php <?php for($i=0;$i<10;$i++) { include_once("staticarray.php"); echo "\n $i". convert(memory_get_usage(true)); } $CITY_DROP=array(); echo "\n $i". convert(memory_get_usage(true)); function convert($size) { $unit=array('b','kb','mb','gb','tb','pb'); return @round($size/pow(1024,($i=floor(log($size,1024)))),2).' '.$unit[$i]; } ?> Expected result: ---------------- I expect memory usage should be same throughout. 02.75 mb 02.75 mb 02.75 mb 02.75 mb 02.75 mb 02.75 mb 02.75 mb 02.75 mb 02.75 mb 02.75 mb 02.75 mb Actual result: -------------- 02.75 mb 12.75 mb 22.75 mb 32.75 mb 42.75 mb 52.75 mb 62.75 mb 72.75 mb 82.75 mb 92.75 mb 102.75 mb ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=66372&edit=1
