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 = 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!
