Try this: <plaintext><?php function fa() {
    foreach ( func_get_args() AS $arg ) {
        if ( is_array($arg) ) {
            foreach( $arg AS $value ) {
                flatten_array( $value );
            }
        } else {
            $GLOBALS['master_arr'][] = $arg;
        }
    }
} $GLOBALS['master_arr'] = array(); fa(array(1,2),array(array(3,4),array(5,6))); print_r($GLOBALS['master_arr']); ?> This does not preserve array keys, but you didn't mention wanting to preserve them. Off the cuff, just threw this together really quickly:
function flatten_array() { $return = array(); foreach ( func_get_args() as $arg ) {
       if ( is_array($arg) ) {
           foreach ( $arg as $k => $v ) {
               if ( is_array($v) ) {
                   $return = array_merge($return, flatten_array($v));
               }
               else {
                   if ( is_numeric($k) and intval($k) == $k ) {
                       $return[] = $v;
                   }
                   else {
                       $return[$k] = $v;
                   }
               }
           }
       }
       else {
           $return[] = $arg;
       }
} return $return; } $flatten = array( 1, 2, 3, 4, array( 5, 6, array( 7, 8, 9, 10, array( 'test' => 11, 'test2' => 12 ), 13 ), 14, 15 ), 16, 17, 18, 19, 20 ); echo "<pre>" . print_r(flatten_array($flatten), true) . "</pre>"; Returns: Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 [4] => 5 [5] => 6 [6] => 7 [7] => 8 [8] => 9 [9] => 10 [test] => 11 [test2] => 12 [10] => 13 [11] => 14 [12] => 15 [13] => 16 [14] => 17 [15] => 18 [16] => 19 [17] => 20 ) This preserves array keys if it's an associative array being flattened. If the array is numerically indexed, it just appends the value to the end. Hope this helps. -- Jeremy C.
