how to remove all non-letters

[kevin bailey]

hi,

it's really late and i'm struggling with this one - so any help gratefully
received.

if i have a string how would i strip out all characters except letters
between a-z and A-Z

i presume this would be using preg_grep but not being a regex guru is making
it hard.

would it be something like?


$subject = "abc-d%ef"; // Want i want to get back is 'abcdef'
$pattern = '/[a-zA-Z]*/';
preg_match($pat tern, $subject, $matches);
// print_r($matche s);

$cleaned_word = matches[0];


thanks,

kev

I'd use preg_replace() instead:

$subject = "abc-d%ef"; // Want i want to get back is 'abcdef'

$pattern = '/[^a-zA-Z]*/';
echo preg_replace($p attern, '', $subject);

Cheers,
Mike Youell.
