function question

if ($_POST['submit']){
   if($_POST['email'] == 'E-mail' || !$_POST['email'] || $_POST['email'] < 5) { 
  die ("Error! : No email entered<br><a href=\"javascript: history.back(-2)\">back</a>");
       }
}

is there anyway i can get something that checks to see if there is an '@' symbol and a '.' in the $_POST['email'] variable, and if @ or . is not in the variable, then kill the script?

i know you can use str_replace() to look for a specific piece of text, then change it and output a new varialbe, i want to just check an email address box to see if they have it semi-correctly filled out, and if not, the die and give the option to go back

is that even possible?

stripos and exit are the answers to your questions young one. Although it woudl be better to use eregi because it is case insensitive and such.

You might want to bookmark the php site (php.net), especially the manual section as it contains a wealth of info.

ya... i was looking around and i saw something about php.net, so i decided to see if it had anything good... just so happend it did

strpos() and stristr(), were exactly what i was looking for (i needed both... one for the problem i posted, one for a different problem)

thanks for the advice
