php opening and closing error message applies to those who do not have permission to modify php.ini. The error message php.ini

Windows system switch php error message

If you do not have the permission to modify php.ini, you can add the following code to the php file:

The code is as follows

ini_set("display_errors", "On");

error_reporting(E_ALL | E_STRICT);

Of course, if you can modify php.ini, as follows:

The code is as follows

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

The method of turning on and off error prompts in Linux system is similar, but I will introduce it to you in detail

Linux system

1. Open the php.ini file.

Take my ubuntu as an example. This file is in the /etc/php5/a(www.jb51.net)pache2 directory.

2. Search and modify the following line, change the Off value to On

The code is as follows

display_errors = Off

3. Search down

The code is as follows

error_reporting = E_ALL & ~E_NOTICE

or search:

error_reporting = E_ALL & ~E_DEPRECATED

was changed to

error_reporting = E_ALL | E_STRICT

4. Modify Apache’s httpd.conf,

Take my Ubuntu as an example. This file is in the /etc/apache2/ directory. This is a blank file.

Add the following two lines:

The code is as follows

php_flag display_errors on
php_value error_reporting 2039

5. Restart Apache and it will be OK.

Restart command: :

The code is as follows

sudo /etc/init.d/apache2 restart

php.ini
to enable error prompts, and error_reporting = E_ALL & ~E_NOTICE to set the error level. You can also set the error prompt in the php file
ini_set('display_errors', 1);//Set the error prompt
error_reporting('E_ALL & ~E_NOTICE ');//Error level prompt

This is an important syntax error

If you want to block errors, add

error_reporting(0);

to the PHP header to block error prompts However, when there is an error in PHP, you can only see a blank page on the browser

Find
error_reporting
in PHP.INI and set it to
error_reporting =0
Note that if there is If there is a semicolon, remove the preceding semicolon

Don’t forget to restart Apache or related web services
