Syntax
Quote: |
array array_map ( callback callback, array arr1 [, array ...] )
| Description
array_map() returns an array containing all the elements of arr1 after applying the callback function to each one. The number of parameters that the callback function accepts should match the number of arrays passed to the array_map()
Example
PHP Code: <?php
function cube($n)
{
return($n * $n * $n);
}
$a = array(1, 2, 3, 4, 5);
$b = array_map("cube", $a);
print_r($b);
?> This makes $b have:
Code: Array
(
[0] => 1
[1] => 8
[2] => 27
[3] => 64
[4] => 125
)
