For any reason I found that some keys were erased for any reason after using it like the example bellow. Test script: --------------- $word = 'metheor'; $arr = []; echo strlen($word); //It shows the lenght of the word for ($i = 0; $i < strlen($word); $i++){ $arr[] = $word[$i]; } print_r($arr); //It shows the full word print_r(array_fill_keys($arr, 0)); //It shows the word filled with 0's but without repeated characters Expected result: ---------------- array([m]=>1, [e]=>1, [t]=>1, [h]=>1, [e]=>1, [o]=>1, [r]=>1) Actual result: -------------- array([m]=>1, [e]=>1, [t]=>1, [h]=>1, [o]=>1, [r]=>1) -- Edit bug report at https://bugs.php.net/bug.php?id=68429&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=68429&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=68429&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=68429&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=68429&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=68429&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=68429&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=68429&r=needscript Try newer version: https://bugs.php.net/fix.php?id=68429&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=68429&r=support Expected behavior: https://bugs.php.net/fix.php?id=68429&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=68429&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=68429&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=68429&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=68429&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=68429&r=dst IIS Stability: https://bugs.php.net/fix.php?id=68429&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=68429&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=68429&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=68429&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=68429&r=mysqlcfg
