From: Arne dot Heizmann at csr dot com Operating system: Windows 2000 PHP version: 5.2.4 PHP Bug Type: PCRE related Bug description: preg_split() swallows part of the string Description: ------------ The following example code shows how preg_split() - when used with PREG_SPLIT_NO_EMPTY - omits pieces which aren't empty. The returned array SHOULD contain ALL of the characters from the original string minus the characters that match the separator. In my example, the separator is a zero-width match. I notice that this problem was reported as Bug #15413 before and marked "Bogus". My example shows that the bug is real. Reproduce code: --------------- <? header ('Content-type: text/plain'); var_export (preg_split ('/\b/', 'a\'', -1, PREG_SPLIT_NO_EMPTY)); ?> Expected result: ---------------- array ( 0 => 'a', 1 => '\'', ) Actual result: -------------- array ( 0 => 'a', ) -- Edit bug report at http://bugs.php.net/?id=42945&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=42945&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=42945&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=42945&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=42945&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=42945&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=42945&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=42945&r=needscript Try newer version: http://bugs.php.net/fix.php?id=42945&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=42945&r=support Expected behavior: http://bugs.php.net/fix.php?id=42945&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=42945&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=42945&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=42945&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=42945&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=42945&r=dst IIS Stability: http://bugs.php.net/fix.php?id=42945&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=42945&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=42945&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=42945&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=42945&r=mysqlcfg
