note 43006 added to function.str-ireplace

After some tests i noticed that str_ireplace isn't always faster as preg_replace with the i-modifier. str_ireplace when the needle appears in the result in lower letters (so "test" will be replaced faster as "TEST"). Doing the same test with a string which contained only capital letters was almost 7-8x slower then a string which contained only lowercase letters. preg_replace however didn't have any problems with capital letters and kept the same speed. Also the length of needle seemed to have an influence on the speed of str_ireplace, but this difference isn't that spectacular, but again it seems to be slower when the needle is longer. However this tests were done with PHP5 RC2 (on IIS) and str_ireplace probably wasn't fully optimized, str_ireplace was only faster on a string with lowercase letters AND with a short needle. ---- Manual Page -- http://www.php.net/manual/en/function.str-ireplace.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+43006 Delete -- http://master.php.net/manage/user-notes.php?action=delete+43006&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+43006&report=yes Search -- http://master.php.net/manage/user-notes.php
