array_map
(PHP 4 >= 4.0.6)
array_map -- Applies the callback to the elements of the
given arrays
Description
array array_map ( mixed callback, array arr1 [, array ...])
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 1. array_map() example
<?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:
Array
(
[0] => 1
[1] => 8
[2] => 27
[3] => 64
[4] => 125
)
