Modify PHP.ini to let screen program error messages

To provide you with a little information:

Display_errors = On

PHP defaults to open error message display, we change it to:

Display_errors = Off

When the error display is turned off, the PHP function does not display the wrong information to the user, which in some way prevents the attacker from knowing the physical location of the script from the error message, as well as some other useful information, at least causing a certain obstacle to the attacker's black box detection. These error messages may be useful to us and can be written to the specified file, then modify the following:

Log_errors = Off

To

Log_errors = On

and the specified file, locate the following line:

; error_log = filename

Remove the previous note, change the filename to the specified file, such as/usr/local/apache/logs/php_error.log

Error_log =/usr/local/apache/logs/php_error.log

So all the mistakes will be written in the Php_error.log file.
