Hi, I am a n00b and don't know how to write descriptive titles!

[LiamProductions]

Hey.

 

Right...

 

How would i check if this string has a @ and a . in it? for example

 

<?php 

$email = "Yourface@lighthand.com";

if($email has a @ in the string and has a . in the string) { 
   echo "This has more possiblites of an email than without them";
}
else {
   echo "We could not tell if this is a email because there is no @ or dot";
}
?>

 

Point out the function or tell me how to do it

 

[Wuhtzu]

You should use regex for that task... do a search for "php email regex".

 

 

[rarebit]

yeah... as Wuhtzu says,

 

or you could do two strstr's or look at following

http://uk3.php.net/manual/en/function.preg-match.php, this states that

"([-!#$%&'*+/=?_`{|}~a-z0-9^]

+(\.[-!#$%&'*+/=?_`{|}~a-z0-9

^]+)*|"([\x0b\x0c\x21\x01-\x08\

x0e-\x1f\x23-\x5b\x5d-\x7f]|\\[\x

0b\x0c\x01-\x09\x0e-\x7f])*")@((

[a-z0-9]([-a-z0-9]*[a-z0-9])?\.)+[

a-z0-9]([-a-z0-9]*[a-z0-9]){1,1}|

\[((25[0-5]|2[0-4][0-9]|[01]?[0-9]

[0-9]?)\.){3,3}(25[0-5]|2[0-4][0-9

]|[01]?[0-9][0-9]?|[-a-z0-9]*[a-z0

-9][\x0b\x0c\x01-\x08\x0e-\x1f\

x21-\x5a\x53-\x7f]|\\[\x0b\x0c\x0

1-\x09\x0e-\x7f])+)\])"

is the correct expression to use, lol

[freakstyle]

<?php
$EmailValString = '^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$' ;
if ( !eregi($EmailValString, $_POST['email']) ) :
    echo "This is not a valid email";
else : 
    echo "this is an acceptable formated email";
endif ; 

 

enjoy, ps reg came from zend so its sold

[marcus]

$email = $_POST['email'];

$checkemail = "/^[a-z0-9]+([_\\.-][a-z0-9]+)*@([a-z0-9]+([\.-][a-z0-9]+)*)+\\.[a-z]{2,}$/i";
if(!preg_match($checkemail,$email)){
echo "E-mail is invalid\n";
}else {
echo "E-mail is valid";
}

I've always used this which I wrote but its probably not great, but i thought i would add it anyways

 

<?php
if (!eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[_a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$", $email))
{ 
// False
} else
{
	// True
}
?>
