@mysql_connect and mysql_connect

Question

I have no problem connecting to a database using PHP however in some scripts I have tested, I have seen a small difference in the connect command.

What is the differenc

Answer 1

If don't use any option something like this;

if ("I'm just making test on my srv") {
   error_reporting(E_ALL);
} else {
   error_reporting(0);
}

Then, it could be recommended for this situation;

$conn = @mysql_connect(...);
if ($conn === false) {
   // handle error
}

Or;

@mysql_connect(...) or die("Could not connect to ...");

So, @ suppresses the error if it exist at the line "where the suppressible function is used".

// Suppressible? Yes, cos you can not apply @ to die, exit, eval ... functions if these are structural functions.
