How to solve 500 error on server in php
After new PHP users set up the development environment in the initial stage, when a syntax error occurs during development, the server returns 500 (server internal error) instead of returning an error message. At this time, you need to make some configurations in the development environment to help you quickly find the cause of the problem, locate the problem, and solve the problem.
Find the php configuration file /etc/php.ini
Configuration parameter value:
display_errors = On error_reporting = E_ALL | E_STRICT
Restart the apache service
service httpd restart
At this time, the browser can already output error messages.
You need to configure apache again /etc/httpd/conf/httpd.conf
Add two lines at the end of the apache configuration file:
php_flag display_errors on php_value error_reporting 2039
Restart apache.
The setting of parameters in php.ini can also be done in php code.
Call: call ini_set() function
//开启php.ini中的display_errors指令 ini_set('display_errors',1); //通过error_reporting()函数设置,输出所有级别的错误报告 error_reporting(E_ALL);
