However, after the product is launched, website operationIt is not appropriate to report so many errors during the process.

1: This kind of error gives a bad impression to the customer
2: When reporting an error, report the absolute path of the website, such as D:www1015 It increases the risk of being attacked
Therefore, after the website is online, the error reporting level should be lowered, reporting fewer errors or even not reporting at all.

 1: Modify the error_reporting option in php.ini
 2: You can use the error_reporting() function to modify the

error level in the php page. The error level is represented by a binary value: 1111 1111 1111 111 from left to right, the 1 on each bit represents an error level
