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.
Tip: You can assign one array to the function, or as many as you like.
Syntax
array_map(functionname, array1, array2, array3, ...)
Example
Send each value of an array to a function, multiply each value by itself, and return an array with the new values:
<?php
function myfunction($val)
{
return($val*$val);
}
$a=array(1,2,3,4,5);
print_r(array_map("myfunction",$a));
?>
