preg_match

[dreamwest]

Im trying to match this string, but i dont wat to match normal words like "hello world 646"

 

$string = "2ab055843241f20044af82ae0d5ace04"; //always over 15 chars - without spaces

if ( preg_match('~^[0-9\s]+$~D', $string)) {
echo 'yes';
}

 

If i can do it with preg_match that would be great

Try this:

 

preg_match('~^[0-9a-f]{32}$~', $string)

 

I'm assuming you want 32 hexadecimal digits

cool!  I never would have figured it out
