array_map()
The array_map() function sends each value of an array to a user-made function, and returns an array with new values, given by the user-made function.
Syntax:array_map(myfunction,array1,array2,array3...)
In above syntax,"myfunction" specifies the name of the user-made function, or null, "array1" specifies an array, "array2" specifies another array and "array3" specifies another array.
Example:
<?php
function myfunction($num)
{
return($num+$num);
}
$a = array(1,2,3,4,5);
print_r(array_map("myfunction",$a));
?>
Output:
Array ( [0] => 2 [1] => 4 [2] => 6 [3] => 8 [4] => 10 )
