PHP is a popular open-source scripting language used for web development. One of the features of PHP is output buffering, which can be used to improve the performance of web applications by reducing the number of server requests. However, in some cases, output buffering can cause issues such as delays in displaying content or incomplete page rendering. Disabling output buffering in PHP can help resolve these issues.
In this guide, we will show you how to turn off or disable output buffering in PHP via php.ini configuration file. This method will disable output buffering globally for all PHP scripts on the server.
Step 1: Locate php.ini file
The first step is to locate the php.ini configuration file on your server. The location of the file may vary depending on your server configuration. You can find the location of php.ini by creating a new PHP file with the following code:
<?php phpinfo(); ?>
Save the file and open it in your web browser. Look for the “Loaded Configuration File” section, which will display the location of the php.ini file.
Step 2: Edit php.ini file
Once you have located the php.ini file, open it with a text editor. Look for the following line:
output_buffering = 4096
This line sets the default output buffering value to 4096 bytes. To disable output buffering, simply set the value to 0:
output_buffering = 0
Save the file and exit the text editor.
Step 3: Restart web server
After editing the php.ini file, you need to restart your web server for the changes to take effect. The method to restart the web server may vary depending on your server setup.
[root@geek ~]# /etc/init.d/httpd restart
Step 4: Test
To test whether output buffering has been disabled, create a new PHP file with the following code:
<?php echo "Output buffering disabled"; ?>
Save the file and open it in your web browser. If output buffering has been disabled, you should see the text “Output buffering disabled” displayed immediately without any delays.
Commands Mentioned:
- phpinfo() – displays PHP configuration information
Conclusion:
In this guide, we have shown you how to turn off or disable output buffering in PHP via php.ini configuration file. Disabling output buffering can help resolve issues such as delays in displaying content or incomplete page rendering. Remember to restart your web server after editing the php.ini file for the changes to take effect.
