Apply function to an array

Anon

Hi all,

Does anyone know how to apply a function to alter every element of an array?

function myfunct ($string)
{
// code to change characters to
// lowercase then capitalize first letter
}

Instead of doing something like:
<?
$fname = myfunct ($fname);
$lname = myfunct ($lname);
---etc.---
?>

Can't I put everything in an array and do
the function just once?

Something like using the following array:
$form1 = array($fname,$lname,$address1,$city);

$form1[] = myfunct($form1[]); (??)

I tried the above and looping thru a for/next but it didn't work.

Any ideas?

To pass the whole array, you can just use the name:

$my_array = my_funct( $my_array );

This only works if 'my_funct' is expecting an array.

Take a look at the function array_walk.
It does exactly that !

Ok guys I see what was wrong.

I couldn't get that array_walk to work for awhile. After digging thru some PHP books and the net, I noticed I was missing the '&' in front of the argument of my function. That seemed to do the trick and alter my array like I wanted to. I never knew about the ampersign for function arguments.

Thanks,
Jim
