php web page error code 500

After a novice has 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.

1. Find the php configuration file /etc/php.ini

2. Configuration parameter value:

display_errors = On

##error_reporting = E_ALL | E_STRICT

3. Restart the apache service

service httpd restart

4. You need to configure the apache/etc/httpd/conf/httpd.conf file again

php_flag display_errors on

php_value error_reporting 2039

5. Restart apache

Setting parameters in php.ini can also be done in php code.

Call: Call the 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);
