How to open or close error prompts in php

There are two ways to open error prompts in php:

1. Modify the php.in file

in the file directory Find the php configuration file, which is php.ini.

Look for the 'display_errors' keyword in php.in and find 'display_errors = Off ' or 'display_errors = On'. Off means turning off the error prompt. On turns on the error prompt, which can be modified according to your needs.

2. Use the error_reporting() function

Syntax:error_reporting(report_level)

report_level: optional. Specifies the error reporting level for the current script. Both value numbers and constant names are accepted, however, for compatibility with future PHP versions, it is recommended to use constant names.

Usage:

//禁用错误报告
error_reporting(0);
//报告运行时错误
error_reporting(E_ERROR | E_WARNING | E_PARSE);
//报告所有错误
error_reporting(E_ALL);
