Php asynchronous debugging and online debugging of website programs

What should I do when a website needs to run continuously but debugging program errors of the website? Is it based on experience or simply printing error messages for them to output on the page?

Below we will share a debugging method that meets both of these conditions to facilitate website program error debugging without affecting the normal operation of the website. Copy the following php statement to the top of the public code.

// Ini_set ('error _ report', E_ALL ^ E_NOTICE); // display all ini_set ('error _ report', E_ALL) error messages except the notice type ); // display all error messages ini_set ('display _ errors ', off); // disable the output of error messages to the output end ini_set ('Log _ errors', On ); // enable the error log record ini_set ('error _ log', 'c:/phpernote'); // define the storage location of the error log

In addition, add two commonly used PHP statements for troubleshooting error messages:

@ Ini_set ('memory _ limit ', '500m'); // sets the maximum memory occupied by the program to 180 MB @ ini_set ('max _ execution_time', '123 '); // set the maximum execution time of the program to 180 seconds
