@unknown (ironic huh)

you can always do this:
$str =@ $_POST["something"];

The & operator is used when you pass a variable to a function to tell PHP to pass it by reference instead of passing it by value (copy on write), like this:

$var = “foo”;
some_fiunction(&$var);

Unlike C++, in PHP the caller chooses when to pass by value and when to pass by reference. In C++, the function writer indicates this with the & character in the function signature.

The @-Operator is really slow.
And do NOT use it for assignments like
@$var = $_POST['var'];
please use
$var = isset($_POST['var'])?$_POST['var']:’my default value’;
PS: Always use error_reporting(E_ALL) and respect the warnings and notices.

Hey,

thanks for your article. I was about to go crazy searching for it. Asking Mr. G00gle would not help using the “@” symbol ;-)”.

BTW, @ is a cool feature of PHP

cheers

Thanks for the article.

One additional note: When use your own error handler, it is very useful to check the return value of error_reporting(). This will return 0, if the “@” operator was used to suppress errors.
