if statement

[Boujii]

I am trying to write an if statement like this:

[PHP]
$email = $_POST['email'];
if ( "@" !isin '$email' ) {
echo "Not a valid email address!<br />";
return;
}
[/PHP]

What i am trying to do is give message and return if @ is not in $email variable. I don't know the PHP equivelent for isin. Cannot use == because @ can be anywhere in the $email variable.

good day sir...i have this simple code:

[PHP]$mystring = 'a@bc';
$findme = '@';
$pos = strpos($mystring, $findme);

if ($pos === false) {
echo "The string '$findme' was not found in the string '$mystring' <br>";
} else {
echo "The string '$findme' was found in the string '$mystring'";
echo " and exists at position $pos <br>";
}[/PHP]

you can modify this little code to fits your needs...
hope it'l helps...more power :)
