How to take effect after modifying php.ini configuration options

PHP is a popular server-side scripting language primarily used for web development. PHP scripts are executed by the server and configured through the php.ini file. The php.ini file contains various configuration options for PHP, such as memory limits, upload file size limits, etc. Modifying the configuration options of php.ini is essential, but after modification, we need to make the modification effective to see the effect. So, let me introduce to you how to modify the php.ini configuration options to take effect.

1. Find the path to the php.ini file

Before modifying the php.ini configuration options, we first need to know the path to the php.ini file. In Linux systems, the php.ini file is stored in the /etc/php.ini path by default, while in Windows systems, it is configured in the php.ini file in the PHP installation directory. If you cannot determine the path to the php.ini file, you can find the path to php.ini by entering the "php --ini" command in the console.

2. Modify php.ini configuration options

Modify php.ini configuration options. You can open the php.ini file through a text editor to find and modify the target options. For example, if we need to increase the file size limit allowed by PHP to 100MB, we need to modify the following options in the php.ini file:

upload_max_filesize = 100M
post_max_size = 100M

After modification, save and close the php.ini file.

3. Restart the Web server

When we modify the php.ini configuration options, the modification will not take effect immediately. PHP needs to re-read the configuration file and restart the web server for the modification to take effect. We can restart the Web server through the following methods:

• Under Linux system, you can use the following command to restart the Apache server:

sudo service apache2 restart

• Under Windows system, you can control Enter the following command in Taichung to restart the IIS server:

iisreset

After restarting the web server, PHP will re-read the php.ini configuration file, and the modifications made in the php.ini file will also take effect.

4. Check if the modification has taken effect

Finally, in order to ensure that the modification has taken effect, we need to check whether the modification was successful. You can use the phpinfo() function to view all configuration information of PHP to determine whether the modification is successful. You can create a file named info.php and add the following code in the file:

<?php
phpinfo();
?>

Enter http://localhost/info.php in the browser to visit the URL Afterwards, a page containing PHP configuration information will appear. Through this page, we can check whether the configuration options have taken effect.

Summary:

PHP is a very important server-side scripting language and plays an important role in Web development. In the process of using PHP, configuration by modifying the php.ini file is very necessary and can meet development needs. The above steps can help you modify the php.ini configuration options and make the modifications effective.
