Edit report at https://bugs.php.net/bug.php?id=55451&edit=1 ID: 55451 Patch added by: datibbaw@php.net Reported by: datibbaw@php.net Summary: substr_compare and case sensitivity Status: Open Type: Feature/Change Request Package: Unknown/Other Function Operating System: NA PHP Version: Irrelevant Block user comment: N Private report: N New Comment: The following patch has been added/updated: Patch Name: substr_compare_optlen Revision: 1313682989 URL: https://bugs.php.net/patch-display.php?bug=55451&patch=substr_compare_optlen&revision=1313682989 Previous Comments: ------------------------------------------------------------------------ [2011-08-18 15:55:57] datibbaw@php.net Description: ------------ The $length parameter of this function is optional in the documentation, but currently it can't be skipped to only set the case sensitivity flag. Values like null or false get converted into 0 which causes a warning and the function returns false. Using null to skip the $length parameter would be nice. Test script: --------------- <?php // should output: 0 echo substr_compare("hello World", "world", 6, null, true), PHP_EOL; ?> Expected result: ---------------- 0 Actual result: -------------- Warning: substr_compare(): The length must be greater than zero ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=55451&edit=1
