I have the following code on a page
Code: Select all
<?php
$send = mail($to,$subject,$message,$headers);
?>
<?php
if(@$send == 1)
{
?>
Notification email sent
<?php
}
?>
and i want to know what the function of the @ symbol is before the $send

It's an
error control operator and its use should mostly be avoided.

Besides, in this case there's absolutely no reason to use it: there's no possible error that can result from trying to use $send.

so your saying
Code: Select all
<?php
$send = mail($to,$subject,$message,$headers);
?>
<?php
if($send == 1)
{
?>
Notification email sent
<?php
}
?>
should be used?

Yes. The most important point is what Celauran said: avoid @. It suppresses warnings and errors that may be very important to you.
