note 4643 deleted from stristr by ronabop

Be careful in code near a stristr call. It seems that php tries to reuse variables where possible so that in a code snippit like: $temp = $variable; $output = stristr ($something, $variable); The variable $temp is converted to lowercase as well as $variable. (Just two pointers to the same location I guess). A workaround is to make the assignment line: $temp = $variable.""; or even shorten the code to: $output = stristr($something, $variable."");
