RE: [PHP] Extracting Numbers from a string.

OK y'all, go ahead and shoot me, but this is what I'd do: $mystring="enters $56.55 for example"; $mynumber=$mystring+1-1; $mynumber now equals 56.55 If you want the . to go to, use the other methods. -----Original Message----- From: Jason Caldwell [mailto:jason@thinkingman.org] Sent: Wednesday, September 11, 2002 3:31 PM To: php-general@lists.php.net Subject: [PHP] Extracting Numbers from a string. I need to extract the numbers only from a field. For example: I have an AMOUNT field and so that I can filter out any user typo's I would like to extract the numbers only. If the user enters $56.55 for example or just $56 then I would like to be able to remove the "$" and the "." keeping just the 56 or 5655. Can I use eregi_replace() to do this -- I've been trying but it doesn't seem to work right. Thanks.
