Description: ------------ --- >From manual page: http://www.php.net/function.array-merge#refsect1-function.array- merge-description --- Test script: --------------- foreach($cols as $key => &$value) { if(array_key_exists($key, $fields)) { $value = array_merge($fields[$key], $value); } } foreach($fields as $key => $value) { if(!array_key_exists($key, $cols)) { $cols[$key] = $value; } } Expected result: ---------------- Expected result is that col becomes is an array with all the values that where already defined added with the values from fields. Actual result: -------------- The sub-array in cols wich was merged with the same sub-array in fields becomes overwritten everytime the next foreach statement accesses the value $value, witch result. the fix for this is to have a diffrent name for the array merging, this leads me to belive that array_merge keeps re-evaluating the values. -- Edit bug report at https://bugs.php.net/bug.php?id=64005&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=64005&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=64005&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=64005&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=64005&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=64005&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=64005&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=64005&r=needscript Try newer version: https://bugs.php.net/fix.php?id=64005&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=64005&r=support Expected behavior: https://bugs.php.net/fix.php?id=64005&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=64005&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=64005&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=64005&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=64005&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=64005&r=dst IIS Stability: https://bugs.php.net/fix.php?id=64005&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=64005&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=64005&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=64005&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=64005&r=mysqlcfg
