Test script: --------------- $inputArray = array( 'shipping' => array( 'after' => array(), 'before' => array(), '_code' => 'shipping' ), 'freeshipping' => array( 'after' => array(), 'before' => array(), '_code' => 'freeshipping' ), 'discount' => array( 'after' => array('shipping', 'tax_shipping'), 'before' => array(), '_code' => 'discount' ), 'tax_shipping' => array( 'after' => array('shipping'), 'before' => array('discount'), '_code' => 'tax_shipping' ) ); function compare ($a, $b) { $aCode = $a['_code']; $bCode = $b['_code']; if (in_array($aCode, $b['after']) || in_array($bCode, $a['before'])) { $res = -1; } elseif (in_array($bCode, $a['after']) || in_array($aCode, $b['before'])) { $res = 1; } else { $res = 0; } return $res; } uasort($inputArray, 'compare'); var_dump(array_keys($inputArray)); Expected result: ---------------- array (size=4) 0 => string 'shipping' (length=8) 1 => string 'tax_shipping' (length=12) 2 => string 'discount' (length=8) 3 => string 'freeshipping' (length=12) Or another position for 'freeshipping'. But 'shipping' must be before 'tax_shipping' and 'discount' must be after 'tax_shipping'. Actual result: -------------- array (size=4) 0 => string 'tax_shipping' (length=12) 1 => string 'discount' (length=8) 2 => string 'freeshipping' (length=12) 3 => string 'shipping' (length=8) -- Edit bug report at https://bugs.php.net/bug.php?id=66544&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=66544&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=66544&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=66544&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=66544&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=66544&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=66544&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=66544&r=needscript Try newer version: https://bugs.php.net/fix.php?id=66544&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=66544&r=support Expected behavior: https://bugs.php.net/fix.php?id=66544&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=66544&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=66544&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=66544&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=66544&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=66544&r=dst IIS Stability: https://bugs.php.net/fix.php?id=66544&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=66544&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=66544&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=66544&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=66544&r=mysqlcfg
