PHP array merge from unknown number of parameters

Question

I have an PHP array looking like this:

$array[\'my_data\'][\'value\'] = \'some value\';
$array[\'my_own_data\'][\'value\'] = \'another value\';
$array[\'diff         


        

Answer 1

If I understand what you want, you could use array_map.

To change:

$a = array();
$a['x']['value'] = 1;
$a['y']['value'] = 3;
$a['z']['value'] = 3;

into:

array(3) {
 ["x"]=>
 int(1)
 ["y"]=>
 int(2)
 ["z"]=>
 int(3)
}

You could define a function:

function f($x) { return $x['value'];}

and use array_map:

$b = array_map(f, $a);
