PHP Development of friends know, in fact, the most worrying is that there are some exceptions or errors in the program, these conditions if the output to the user's screen will be frightened users, and even lost their work, if not output to the screen must find a way to log, but it seems not everyone has the habit of viewing the error log, To solve this embarrassing problem, so I wrote this code, the intention is that when we write a PHP program error when the wrong content is captured and sent to our email.
First look at the effect:
Copy CodeThe code is as follows:
Define (' Sys_debug ', false);
IF (Sys_debug) {
Ini_set (' display_errors ', ' on ');
Error_reporting (E_all);//Use this setting after online error_reporting (E_error | e_warning | E_parse);
}else{
Ini_set (' display_errors ', ' off ');
error_reporting (0);
}
Error trapping
Register_shutdown_function (' Fun::error ');
Class fun{
/**
General error Handling
Parameters:
What to output, whether to terminate the execution of the program
Description
This function can be used to output custom error content when there is a pass value
In addition, the register_shutdown_function can be used to automatically crawl the error content and send the wrong content to the email.
The mechanism for register_shutdown_function is to invoke a function when the program finishes or midway through an error
If it is called when an auto-fetch error occurs, the last error is made, and if no error is found, the message jumps out
Return:
Content will be output directly to the screen or email
Usage:
Fun::error (' error content ');
Fun::error (' Error content ', False);
/**/

$M =trim ($M);
IF ($M! = ") {//Manual call
