What is the @ in php used for?

 

Like @mysql_connect

@. I don't recommend it.

Ok, I was also wondering what does -> do? I have seen in some scripts people have ->.

 

Like $db->query

@ suppresses errors. Can come in handy, but only recommend using in a production environment, after all testing is done, with a strong ability to debug, and a lot of error checking in your code. AKA - avoid using it unless you know what you're doing.

 

-> is referencing a method or variable within an object or class.

 

Example

 

<?php

class test {

    public function someMethod() {
        echo 'Hello world!';
    }

}

$obj = new test;

$obj->someMethod();

?>
