PHP regex to find any number at the beginning of a line

Question

I am using PHP and I hope that I can create a regular expression that will find and return the street number of the address.

Example:

1234- South Blvd. Washington DC, APT # 306, ZIP45234

In the above example, only 1234 will be returned.

It sounds like it should be incredibly simple, but I haven't got it yet. Any help would be greatly appreciated.

This will probably happen in many cases - the address line does not always start with a line of numbers, etc.

Try the following:

$str = "1234- South Blvd. Washington D.C., APT #306, ZIP4523";
preg_match("~^(\d+)~", $str, $m);
var_dump($m[1]);

string(4) "1234"
