Multi-Dimensional array count in PHP

Question

I have a multi-dimentional array set up as follows

array() {     ["type1"] =>     array() {         ["ticket1"] =>         array(9) {             // ticket details here         }         ["ticket2"] =>         array(10) {             // ticket details here         }         ["ticket3"] =>         array(9) {             // ticket details here         }     }     ["type2"] =>     array() {         ["ticket1"] =>         array(9) {             // ticket details here         }         ["ticket2"] =>         array(10) {             // ticket details here         }         ["ticket3"] =>         array(9) {             // ticket details here         }     } } 

etc.

I am trying to get a count of the total number of tickets in the array (number of second level items), but the number of types is variable as are the number of fields that each ticket has, so I cannot use COUNT_RECURSIVE and maths to get the number.

Can anyone help me?

Answer 1

A bit late but this is a clean way to write it.

$totalTickets = array_sum(array_map("count", $tickets)); 

Assuming $tickets is your multi-dimensional array.

I've expanded the code to give an explained example because array_map might be new to some

$tickets = array(     "type1" => array(         "ticket1" => array(),         "ticket2" => array(),         "ticket3" => array(),     ),     "type2" => array(         "ticket4" => array(),         "ticket5" => array(),         "ticket6" => array(),         "ticket7" => array(),     ),     "type3" => array(         "ticket8" => array()     ) );  // First we map count over every first level item in the array // giving us the total number of tickets for each type. $typeTotals = array_map("count", $tickets);  // print_r($typeTotals); // $type_totals --> Array ( //                       [type1] => 3, //                       [type2] => 4, //                       [type3] => 1  //                  )  //Then we sum the values of each of these $totalTickets = array_sum($typeTotals);  print($totalTickets); // $totalTickets --> 8 

So because we don't care about the intermediate result of each type we can feed the result into array_sum

$totalTickets = array_sum(array_map("count", $tickets)); 

Answer 2

$count = 0; foreach ($array as $type) {     $count+= count($type); }
