How does php skip when it encounters an error?

PHP skips the error to continue execution:

The @ error control operator can do this.

The @ symbol can ignore errors and has the function of suppressing errors.

For example:

Function db_connect () / / Connect to database {@ $db = mysql_connect ('localhost','root','test'); if (! $db) {throw new Exception (' failed to connect to database! Please try again!');} mysql_select_db ('book'); return $db;}

If the connection to the database is not successful, the previous "@" will be able to suppress the error, that is, it will not show the error, and then throw an exception to show the self-defined exception handling. It is recommended to use less, which will increase the system overhead.
