Error output in PHP is a necessary tool for debugging code. But it can also create potentially vulnerable areas. Therefore, you need to use this mechanism carefully and carefully. After the site or service has passed all stages of testing, you need to make sure that it does not display errors, with which the attacker can gain access to important data.
