#43467 [NEW]: function substr() does not function the same

From: mgd at xpressbillpay dot com Operating system: Windows XP and server 2003 PHP version: 5.2.5 PHP Bug Type: Unknown/Other Function Bug description: function substr() does not function the same 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 bug report at http://bugs.php.net/?id=43467&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=43467&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=43467&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=43467&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=43467&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=43467&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=43467&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=43467&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=43467&r=needscript Try newer version: http://bugs.php.net/fix.php?id=43467&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=43467&r=support Expected behavior: http://bugs.php.net/fix.php?id=43467&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=43467&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=43467&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=43467&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=43467&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=43467&r=dst IIS Stability: http://bugs.php.net/fix.php?id=43467&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=43467&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=43467&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=43467&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=43467&r=mysqlcfg
