#php After a novice has 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.
1. Find the php configuration file /etc/php.ini
Configuration parameter value:
display_errors = On error_reporting = E_ALL | E_STRICT
2. Restart the apache service
service httpd restart
At this time, the browser can already output error messages.
3. Configure apache/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
4. Restart apache
The setting of 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);
This can be used dynamically to output errors in the specified php file.
