$pattern = '/:\d/'; //for a single digit
$pattern = '/:\d{1,5}/'; //single digit, between 1 and 5 times
$pattern = '/:\d+/'; //single digit, between one and unlimited times

if(ereg($pattern, $str)) {
   //it matched!
}

 

Edit: actually, ereg is deprecated:

if(preg_match($pattern, $str)) {
   //it matched!
}

sorry to bump, but on that note, what was ereg? (i'm learning - ish - preg so it does predate me)

It was one of a group of functions that used the POSIX style of Regular Expressions instead of the PCRE style. There is a lot of crossover between the two, but with subtle differences. There is brief explanation of some of the differences in the PCRE section of the manual (which is also linked to from the ereg page).
