Previous Comments: ------------------------------------------------------------------------ [2007-04-28 22:30:41] shshzi at gmail dot com Description: ------------ when using serialize on some large (not huge) array, it will take insane amounts of memory. look at the code , when using size array of 30,000 , the script works as expected, indicating that the output is a mere 2MB in length, while enlarging the array to 50,000 elements causes php to go crazy and hit the 600MB i've allowed him to consume... Reproduce code: --------------- <? $a = array(); for($i=0;$i<50000;$i++) { $a[$i] = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"; } $z = serialize($a); print strlen($z); ?> ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=41220&edit=1
