numbers only

[Jimboidaho]

I am looking for a way to clean up phone numbers before storing. I
have not found a good way to do this and I am not very good at regular
expressions. Here is what I have so far.

$pattern = '/\d*/';
preg_match_all($pattern,'123-456-7890', $matches);
$junk = implode('',$matches[0]);
echo $junk;
echo '<br />';

Seems there should be a better way.

Thanks.

$string = "999-999-9999";
$string = preg_replace("/\D/", "", $string);

Are you trying to get just the numbers out of the string?

That's what I based my answer off of.

If OP's trying to validate the ring-a-ling number, well, that'll take
a bit more than I have up my t-shirt sleeves.

$string='My Phone Number is 1234-000-111';
echo intval($string);
//1234000111

Cheers!

That's what I was looking for. I like storing phone numbers with only
the numbers. Then I can have a consistent format when I display them
on the page.

Thanks.

Hi Ovidui,

This doesn't seem to work for me.
echo intval('123-456-7890');
returns an answer of 123

On the manual page for intval() there is this:

Strings will most likely return 0 although this depends on the leftmost characters of the string.

The way intval() works is to look at the string. If the left most char is a number it will continue to grab the numbers in the string until it comes to a non-numeric char value. Everything it has seen up to that point is returned. If the left most char is a non-numeric value it returns 0. 

For what you're doing I wouldn't use intval(). I'd use a preg_replace on all non numerics, like what Jack posted earlier.
