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
