Unknown operand '@'?

[PickleHead]

if(!@mysql_query(...)) { ... }

What is the '@' called in php/mysql?
What does it do explicitly?

Can you point me to any documentation please.
google returns nothing, or do I have to escape it to search it right?
Can't figure it out, nothing in MySQL page or PHP page, that I can find.
See it in a lot of tutorials, but they just say "dont worry about that just keep going we'll explain it later" but never do.

When an @ precedes a function call this will suppress a possible error message to be send to the clients browser.
Example:

$fp = @fopen("filename","r");

When file 'filename' does not exists, PHP would normally print an error message about an invalid stream or something like that. With the @ in front of fopen this message won't be printed. In this example you can later on check $fp whether an error as occurred:

if ($fp)
{
// handle the file
}
else
{
// handle file not found
}
