ID: 43467 Updated by: iliaa@php.net Reported By: mgd at xpressbillpay dot com -Status: Open +Status: Bogus Bug Type: Unknown/Other Function Operating System: Windows XP and server 2003 PHP Version: 5.2.5 New Comment: Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php . Previous Comments: ------------------------------------------------------------------------ [2007-12-01 11:28:23] felipe@php.net Anyway, says the documentation: "If start denotes a position beyond this truncation, an empty string will be returned." ------------------------------------------------------------------------ [2007-12-01 08:50:51] mgd at xpressbillpay dot com Description: ------------ script using substr($strVal, -10); if $strVal length is less then 10 chars (or less then int start) the return value is empty. In a previous version(I had 5.1.4 before upgrade) substr($strVal, -10); would still return the full #strVal if less then 10 which it should since int start should begin from the last character and count back x number of chars and stop at the first if $strVal is less the the count. Reproduce code: --------------- <?PHP $str = "1234567"; echo substr($str,-8); ?> Expected result: ---------------- 1234567 Actual result: -------------- empty ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=43467&edit=1
