Detailed explanation of how to close PHP error prompt_PHP tutorial

The easiest way is to add the following code directly to the php program code:

Can turn off all notice and warning level errors.

Put this statement in the function include file of your script, usually config.php or conn.php to control the output.

Of course I can also set it in php.ini as follows

Open the php.ini file in the PHP installation directory

Find display_errors = On and change it to display_errors = off

Note: If you have copied the PHP.ini file to the windows directory, you must also change display_errors = On in c:windows/php.ini to display_errors = off

Solution to the failure of display_errors = Off in PHP .ini

Question:

The PHP setting file php.ini has clearly set display_errors = Off, but during operation, error messages still appear on the web page.

Solution:

Open the php.ini file in the PHP installation directory

Find log_errors = off and change it to log_errors = on

Find error_log = filename and change it to error_log="D:PHPerrlogphp_error.log" (the directory and file name here D:PHPerrlogphp_error.log are whatever you want)

Note: If you have copied the PHP.ini file to the windows directory, you must also copy the c:windows/php.ini file.

In addition, php_error.log must have at least USER's modification and write permissions, otherwise the error log cannot be output.

It is often seen that error_reporting (7) means: setting the level of error message reporting.
