email validator

[adicrst]

i have this function that sanitizes the email, but for some reason it doesn't work for white spaces like 'test @test.com'. Why ?

 

$string = '[email protected]';
function spamcheck($mail)
 {
	  $mail = filter_var($mail, FILTER_SANITIZE_EMAIL);
	  if(filter_var($mail, FILTER_VALIDATE_EMAIL))
		{
			return TRUE;
		}
	  else
		{
			return FALSE;
		}
 }

if (spamcheck($string) != FALSE)
{
	$email = $sir;
	echo $email;
}
else
{
	echo '<br />Invalid email address!';
	$error = true;
}

function checkemail($email) {
if(preg_match('#[a-zA-Z0-9][a-zA-Z0-9\.\-\_]*@[a-zA-Z0-9\-\_]*\.[a-zA-Z0-9\_\.\-]*[a-zA-Z0-9]#', $email))
	return true;
else
	diefalse;
}

works, thanks.

Could you clarify for me why my function didn't worked ?

I'm not sure, I think it has something to do with the predefined function and I don't know how its coded.
