Why use "@" before certain PHP functions like mysql_connect?

Using "@" before certain PHP functions, such as mysql_connect, suppresses any error messages or warnings that may be generated by that function. This can be useful in situations where you want to handle errors yourself or prevent error messages from being displayed to users. However, it is generally not recommended to use "@" as it can make debugging more difficult. 

// Example of using "@" before mysql_connect to suppress errors
$connection = @mysql_connect('localhost', 'username', 'password');
if(!$connection){
    echo "Failed to connect to database";
}
