Methods for PHP asynchronous debugging and online debugging of website programs

What should you do when you encounter a website that needs to run uninterrupted but also need to debug program errors on the website? What to do? Should I rely on a little guesswork based on experience, or should I directly print the error message and let it be output on the page?

The following is a method that satisfies these two conditions at the same time. It is a debugging method that facilitates website program error debugging without affecting the normal operation of the website. Just copy the following php statement to the top of the public code.

//ini_set('error_reporting',E_ALL ^ E_NOTICE);//显示所有除了notice类型的错误信息
ini_set('error_reporting',E_ALL);//显示所有错误信息
ini_set('display_errors',off);//禁止将错误信息输出到输出端
ini_set('log_errors',On);//开启错误日志记录
ini_set('error_log','C:/phpernote');//定义错误日志存储位置

Attached are two more commonly used PHP statements for eliminating error messages:

@ini_set('memory_limit','500M');//设置程序可占用最大内存为500MB
@ini_set('max_execution_time','180');//设置允许程序最长的执行时间为180秒
