extrovertive Posted October 7, 2007 Share Posted October 7, 2007 <?php $data = array(1, 2, "cool"=>7, 7=>3, "e"=>array(3,5,7), "blah"=>3, array(2,4,6) ); pr($data); incrementOne($data); pr($data); function incrementOne(&$arr) { foreach($arr as $key=>$val) { if(is_array($val)) incrementOne($val); else{ $arr[$key] = $val + 1; } } } function pr($arr) { echo '<pre>'; print_r($arr); echo '</pre>'; } ?> Based on that code above, I get, Array ( [0] => 1 [1] => 2 [cool] => 7 [7] => 3 [e] => Array ( [0] => 3 [1] => 5 [2] => 7 ) [blah] => 3 [8] => Array ( [0] => 2 [1] => 4 [2] => 6 ) ) Array ( [0] => 2 [1] => 3 [cool] => 8 [7] => 4 [e] => Array ( [0] => 3 [1] => 5 [2] => 7 ) [blah] => 4 [8] => Array ( [0] => 2 [1] => 4 [2] => 6 ) ) The subarrays "e" and 8, I dont get why they dont increment?

GingerRobot Posted October 7, 2007 Share Posted October 7, 2007 You're rather re-inventing the wheel. Try using the array_walk_recursive() function which is specifically for applying a function to every member of a multi dimensional array. Try: <?php $data = array(1, 2, "cool"=>7, 7=>3, "e"=>array(3,5,7), "blah"=>3, array(2,4,6) ); function increment(&$v){ echo $v++; } function pr($arr) { echo '<pre>'; print_r($arr); echo '</pre>'; } pr($data); array_walk_recursive($data,'increment'); pr($data); ?> Quote Link to comment Share on other sites More sharing options...
