To turn off the PHP error script hints

The easiest way to do this is to add the following code directly to the PHP program code:

The code is as follows
Error_reporting (e_all^e_notice^e_warning);

You can turn off all notice and warning-level errors.

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

Of course, I can also be set in the PHP.ini method is as follows

Open the php.ini file under the PHP installation directory

Find display_errors = on modified to Display_errors = Off

Note: If you have copied the php.ini file to the Windows directory, you must also modify the Display_errors = on in C:windows/php.ini to Display_errors = Off

Solution of display_errors = off failure in PHP. ini

Problem:

PHP settings file PHP. ini is already set display_errors = off, but in the running process, the page will still appear error messages.

Solve:

Open the php.ini file under the PHP installation directory

Find log_errors = off modified to Log_errors = On

Find error_log = filename modified to error_log= "D:phperrlogphp_error.log" (Here's the directory and filename d:phperrlogphp_error.log whatever you take)

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

In addition, Php_error.log must have at least user modification and write permissions, otherwise the error log cannot be exported.

Often see error_reporting (7) Direct meaning: Set the wrong message return level.
