If there is an error during the running of the PHP program, whether the error message is displayed on the browser and the level of the error message is what we need to control in the process of program development, debugging and operation.

The following instructions are given to control the shielding and display of PHP error messages (errors) by setting php.ini:

1. Whether the error message is displayed

The copy code is as follows:

Display error display_errors = On

Masking error display_errors = Off (default)

2. The level at which error messages are displayed

The copy code is as follows:

Error_reporting = E_ALL (all)

Error_reporting = E_ALL & ~ E_NOTICE (errors above Notice will be displayed)

Here we generally set it to E_ALL and use the error_reporting () function in the PHP program to set the error message level of the current program.

3. Set whether to save the error log

During the operation of the program, we are generally set not to display errors, so that the running status can be recorded by saving the error log.

The copy code is as follows:

Log_errors = On (record error log)

Log_errors = Off (not recorded)

The copy code is as follows:

Error_log = e:/php/logs/php_error.log
