Open error messages for PHP and Apache

If you use PHP + Apache, under the default settings, PHP encoding errors will not be prompted, which is very inconvenient for development. You can use the following steps to open the error message (cetnos is used as an example here):
1. Open the php.ini file.
This file is in: /etc/php.ini .
2. Search and modify the following line,

display_errors = Off

Change the Off value to On

3. Search for the following line
error_reporting = E_ALL & ~E_ DEPRECATED & ~E_STRICT
Modify to
error_reporting = E_ALL | E_STRICT

4. Modify Apache’s httpd.conf,

Add the following two lines in /etc/httpd/conf/httpd.conf

：
php_flag display_errors on
php_value error_reporting 2039
5. Restart Apache and it will be OK.
