Re: Extracting Numbers from a string.

it doesn't use ereg, but it (should) would work: $mystring = "I have $56.55 dollars, don't you know"; $mystring = substr($mystring, strpos($mystring, "$")); //strip out after the $ sign $mystring = substr($mystring, 0, strpos($mystring, " ")); //keep only till first space //mystring now contains $56.55 if you want it split into two variables, of '$56', and '55' use: $a = explode(".", $mystring); //$a[0'] = $56 //$a[1] = 55 (by the way, there may be functions that work better than using the substr+strpos functions, I just can't remember off the top of my head!) Of course, ereg might well work better!
