After PHP novices set up the development environment in the early 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.

service httpd restart

php_flag display_errors on php_value error_reporting 2039
