PHP prompts Warning: Unknown after turning on display_errors

Question

How to solve this error?

The code is very simple:

<?php
ini_set('display_errors', true);

Prompt error message:

Warning: Unknown: failed to open stream: Permission denied in Unknown on line 0

I have found many similar error messages on the Internet, but they all have a Fatal Error after warning. I only have this line warning level error message.

Answer 1

1. This configuration should be configured in php.ini;

2. Because the file does not have write permission, just enable the file write permission in the directory.

Answer 2

Configuration error prompt

<?php

ini_set("display_errors",On);
ini_set("error_reporting",E_ALL);//错误日志级别

Error resolution

Permission error is expressed in English. Please check whether a file you are operating has permissions that are readable, writable, readable, or executable
