I have my website completely made in PHP. But I m stuck in the Email address validation. How can i do that with PHP
By using regular expressions.
Take your pick of email expressions from regexlib.com

Don’t try to re-invent the wheel.
Just don’t use Swift Mailer’s embarrassing monstrosity:

Absurd
I have this one that is being used for several projects.
function checkEmail($email){
# First,we check that there's one @ symbol, and that the lengths are right
if(!ereg("^[^@]{1,64}@[^@]{1,255}$", $email)){
# Email invalid because wrong number of characters in one section, or wrong number of @ symbols.
return false;
}
# Split it into sections to make life easier
$email_array = explode("@", $email);
$local_array = explode(".", $email_array[0]);
for($i = 0; $i < sizeof($local_array); $i++){
if(!ereg("^(([A-Za-z0-9!#$%&'*+/=?^_`{|}~-][A-Za-z0-9!#$%&'*+/=?^_`{|}~\\.-]{0,63})|(\\"[^(\\\\|\\")]{0,62}\\"))$", $local_array[$i])){
return false;
}
}
if(!ereg("^\\[?[0-9\\.]+\\]?$", $email_array[1])){ # Check if domain is IP. If not, it should be valid domain name
$domain_array = explode(".", $email_array[1]);
if(sizeof($domain_array) < 2){
return false; # Not enough parts to domain
}
for($i = 0; $i < sizeof($domain_array); $i++){
if(!ereg("^(([A-Za-z0-9][A-Za-z0-9-]{0,61}[A-Za-z0-9])|([A-Za-z0-9]+))$", $domain_array[$i])){
return false;
}
}
}
return true;
}
Here is mine:
/**
* Check if an email address is in a standard format.
*
* @param string $value
* @return false|string
*/
public static function isEmail($value)
{
// Tidy up first.
$value = strtolower($value);
$value = str_replace('www.', '', $value);
// The part before the '@' will be called the 'account'.
// The part after the '@' will be called the 'host'.
$accountChars = preg_quote('a-z0-9-_\\.+', '/');
$hostChars = preg_quote('a-z0-9-', '/'); // dot excluded dileberatly.
$match = preg_match("
/^
[{$accountChars}]+ # account
@
[{$hostChars}]+(\\.[{$hostChars}]+)* # host
$/ix",
$value);
// If the match is fine, return the clean email address; else false.
return (($match === 1) ? $value : false);
}
You can also use regex…
Really simple: http://www.totallyphp.co.uk/code/validate_an_email_address_using_regular_expressions.htm
Maybe, but RFC822 compliant. Unlike other solutions offered in this thread, choose your hammer wisely.
This.
I’m in favor of the php filter solution proposed or going with this : http://www.linuxjournal.com/article/9585?page=0,3 (read the first page to understand what it does).

Not sure if you are being sarcastic, but thanks anyway
