I have tested on Ubuntu with 5.3.2 and 5.3.5 and the bug is not present and the script works. ------------------------------------------------------------------------ [2011-03-11 23:33:42] amarasatish at gmail dot com I am having a php file which parses the meta tags out of the html report files and display them in a table. Until now it has wroked fine on PHP 5.2.4.4, now after installing the version 5.3.5, the page doesn't load and give an error: "PHP Fatal error: Out of memory (allocated xxxxxx) (tried to allocate xxxxxx 01 bytes) in File on line xx.". I start increasing the memory allocation in php.ini almost upto 1000MB, but still the same error. If i downgrade to PHP 5.2.4.4, its working again. What could the problem be? For some reason, the Test Script given here, gives the same error message on version PHP 5.3.5, 5.2.4.4, 4. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
