PHP Notice: Undefined index error message solution_PHP tutorial

In the past two days, I installed a new server and changed it to Apache+PHP5.4.3. After configuring it and running the PHP website, an error message appeared: "PHP Notice: Undefined index..."

The specific information is:

　PHP Notice: Undefined index: page in d:myqyandread.php on line 56

I personally think that this error message may be a php.ini configuration problem.

Solution:

Open the PHP configuration file php.ini, search for error_reporting, and find the following line:

error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT

Modified to:

error_reporting = E_ALL & ~E_NOTICE

Then just restart apache.
