What does @ do?

[trading_jacks]

I am new to php and google doesn't allow for searching on the @
symbol.

I have a script with the following line:

if (@$type_toggle || @cat_toggle) {
do_query....... .

What does the @ do? Can you give me a link so I can read about it.

Thanks!

it surpresses error messages, so that if the variable "$type_togg le" or
"$cat_toggl e" doesn't exist, error messages/warnings will not be printed to
the screen.

or "$cat_toggl e" doesn't exist, error messages/warnings will not be

and by the way, in relation to the "register_globa ls" questions that have
gone around the last couple of days, the script above is a perfect example
of why register_global s should be turned off.

if register_global s is on, simply checking for a variable will ALWAYS
return true, so in the code above, $type_toggle and $cat_toggle BOTH exist
and the query will ALWAYS be performed.

Then, to avoid ambiguous comparison, use clarifying functions.

In the example showed above:

if(!empty(@$typ e_toggle) || !empty(@cat_tog gle))
{
do_query....... .

To make sure You have non-empty array $arr:

if(is_array($ar r) && count($arr))
{
do_something();
}

Notice: it is not enough to check for count($var) as far as ordinary variables
always return 1 == count($var), so, construction:
if(count($var))
{
foreach($var as ...)

Will end in "Supplied variable should be an array" in some cases.
