From: Bjorn dot Wiberg at its dot uu dot se Operating system: Debian 5.0.1, IBM AIX 5.3 PHP version: 5.2.9 PHP Bug Type: Unknown/Other Function Bug description: explode() returns empty array if delimiter not found and limit is negative
Description: ------------ It appears that explode() returns an empty array (instead of an array with string in it) if limit is negative and delimiter contains a value that is not contained in string. The documentation of explode() (http://www.php.net/manual/en/function.explode.php, section "Return Values") however states that "If delimiter contains a value that is not contained in string, then explode() will return an array containing string", which then does not hold for negative limits. Reproduce code: --------------- <?php print_r(explode('_', 'test', -1)); print_r(explode('_', 'test_underscore', -1)); print_r(explode('_', 'test')); print_r(explode('_', 'test_underscore')); ?> Expected result: ---------------- Array ( [0] => test ) Array ( [0] => test ) Array ( [0] => test ) Array ( [0] => test [1] => underscore ) Actual result: -------------- bwib...@musica-lp02:~$ php -n -f test.php Array ( ) Array ( [0] => test ) Array ( [0] => test ) Array ( [0] => test [1] => underscore ) -- Edit bug report at http://bugs.php.net/?id=48035&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=48035&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=48035&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=48035&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=48035&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=48035&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=48035&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=48035&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=48035&r=needscript Try newer version: http://bugs.php.net/fix.php?id=48035&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=48035&r=support Expected behavior: http://bugs.php.net/fix.php?id=48035&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=48035&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=48035&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=48035&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=48035&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=48035&r=dst IIS Stability: http://bugs.php.net/fix.php?id=48035&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=48035&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=48035&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=48035&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=48035&r=mysqlcfg
