Description: ------------ If I call preg_split with a string such as ",,foo,,bar,," I expect to get five empty strings back in the returned array, but I only get back two - the first and the last. Reproduce code: --------------- $tokens = preg_split("/[,]+/", ",,foo,,bar,,"); Expected result: ---------------- I expect $tokens to contain the following array: array(12) { [0]=> string(0) "" [1]=> string(0) "" [2]=> string(3) "foo" [3]=> string(0) "" [4]=> string(3) "bar" [5]=> string(0) "" [6]=> string(0) "" } Actual result: -------------- array(12) { [0]=> string(0) "" [1]=> string(3) "foo" [2]=> string(3) "bar" [3]=> string(0) "" } -- Edit bug report at http://bugs.php.net/?id=28755&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=28755&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=28755&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=28755&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=28755&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=28755&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=28755&r=needscript Try newer version: http://bugs.php.net/fix.php?id=28755&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=28755&r=support Expected behavior: http://bugs.php.net/fix.php?id=28755&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=28755&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=28755&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=28755&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=28755&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=28755&r=dst IIS Stability: http://bugs.php.net/fix.php?id=28755&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=28755&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=28755&r=float
