Canadian Posted February 5, 2010 Share Posted February 5, 2010 I'm trying to collect a number from a form and test whether or not the number ends in 999. The book I'm using to learn PHP it uses the ereg() or eregi() functions for regular expressions. I've just learned that these were phased out in PHP 5.3 after receiving and error. I think I have to use preg_match now. Regardless, I'm having some trouble with the syntax. Maybe it changed with preg_match. My code and error is below... Thanks Number Entry Form (just a basic form)... <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>Untitled Document</title> </head> <body> <h1>Enter Your Lucky Number!

scotmcc Posted February 5, 2010 Share Posted February 5, 2010 You need to use a regex format: <?php $entry = "1230999"; if (preg_match('/999$/', $entry)) { echo "You are a winner!!!"; } else { echo "Sorry, better luck next time."; } ?> See: http://us.php.net/manual/en/function.preg-match.php Link to comment https://forums.phpfreaks.com/topic/191019-eregi-to-preg_match-help/#findComment-1007243 Share on other sites More sharing options...
