PHP - set all empty or null in an array, to 0, without a foreach loop -

i'm working large array. we're displaying fields of data in array table. fields in array null because user hasn't accumulated in field. however, wanted 0 when have such result. our solution display value along intval()

intval(@$users[$user_id]['loggedin_time'])

which fine, ugly , inelegant. there way, without foreach loop, set values of '' in array 0?

yes, array_map:

$input = array(...); $output = array_map(function($item) { return $item ?: 0; }, $input); 

the above example uses facilities of php >= 5.3 (inline anonymous function declaration , short form of ternary operator), can same in php version (only perhaps more verbosely).

you should think bit conditional inside callback function; 1 'm using here replace values evaluate false booleans zeroes (this include empty string, includes e.g. null values -- might want tweak condition, depending on needs).

update: php < 5.3 version

it's either this:

function callback($item) {     return $item == false ? 0 : $item; }  $output = array_map('callback', $input); 

or this:

$output = array_map(      create_function('$item', 'return $item == false ? 0 : $item;'),      $input);
