Implementation code for instantly catching errors in PHP and sending email notifications using PHP_PHP Tutorial

Define('SYS_DEBUG',false);
IF(SYS_DEBUG) {
ini_set('display_errors','on');
Error_reporting(E_ALL);//上线后使用该设定Error_reporting(E_ERROR | E_WARNING | E_PARSE);
}Else{
ini_set('display_errors','off');
Error_reporting(0);
}

//错误捕捉
Register_shutdown_function('Fun::Error');

Class Fun{

/**
General error handling
Parameters:
What to output, whether to terminate the program
Description:
When a value is passed, this function can be used to output customized error content
In addition, you can also cooperate with Register_shutdown_function to automatically capture error content and send the captured error content to Email
The mechanism of Register_shutdown_function is to call the function when the program completes execution or an error occurs during the process
If it is an automatic capture error, it will be Called, the last error content will be obtained. If no error content is found,
will pop out. Return:
The content will be output directly to the screen or email.
Usage:
Fun::Error(' Error content');
Fun::Error('Error content',False);
