Several PHP extensions are installed on the scripts servers, but not enabled by default. (Since most scripts do not use these extensions, this saves startup time and memory.) You can load any of these extensions by creating a text file called php.ini in the same directory as your PHP script, and adding a line with:

extension = [extension name].so

one line for each extension you want to enable.

Note that this will override some settings in the global php.ini — most importantly, this will cause magic_quotes_gpc to turn on! You should make sure that your application unsets this option, or set magic_quotes_gpc = no in your own php.ini file.

If your site is composed of several subdirectories, instead of creating a php.ini for each one you can add scripts and then fix-php-ini in the root directory of your site where your php.ini is located. fix-php-ini will traverse the directory and place symlinks as needed.

The following are the extensions installed on the scripts servers, with links to more information about them from the PHP website.

PHP is a popular programming language for web development because of its ease of use and flexibility. PHP extensions are additional modules that enhance the functionality of PHP, such as adding support for different databases or encryption algorithms. Sometimes, users may need to enable or disable PHP extensions on Linux to optimize their server performance or to troubleshoot a specific issue. In this blog post, we will provide a step-by-step guide on how to enable or disable PHP extensions on Linux, as well as helpful tips, best practices, and common issues.

Enabling PHP extensions on Debian-based distros

Debian-based Linux distributions such as Ubuntu, Debian, and Mint use the php5enmod command to enable and php5dismod to disable PHP extensions. Here’s an example of how to enable a PHP extension:

sudo php5enmod module_name

Note that the module name is case-sensitive.

Enabling PHP extensions on Ubuntu

Ubuntu uses a different command than Debian-based distros to enable PHP modules. You can use the phpenmod command followed by the module name to enable specific PHP modules:

sudo phpenmod module_name

Ubuntu also has a built-in module search function that you can use to find a specific PHP module.

Enabling PHP extensions for PHP CLI

PHP CLI (Command Line Interface) has its own configuration file, which means that you’ll need to create a phprc file and load the extension there. After that, you’ll need to kill off all running PHP processes and confirm the changes. Here’s an example of how to enable a PHP extension for PHP CLI:

Be aware that killing off running PHP processes is necessary to apply changes.

Checking which PHP extensions have been enabled or disabled

To check which PHP extensions have been enabled or disabled, you can create a new file named info.php and write the code in it. Here’s an example of how to do this:

The phpinfo() function displays information about PHP configuration, including a list of all enabled extensions. Keep in mind that the info.php file should be deleted after use for security reasons.

Installing PHP extensions on Linux

To install php extensions on linux , you can download and install the extension s manually, and then add them to the php.ini file. Here’s an example of how to install a PHP extension using the apt-get package manager:

sudo apt-get install php-module_name

Note that some extensions may require additional dependencies, and the php.ini file may be in a different location depending on the Linux distribution.

Installing all required PHP extensions for Laravel

Laravel is a popular PHP web application framework that requires several PHP extensions to function properly. You can use the Composer package manager to install all the required PHP extensions automatically. Here’s an example of how to do this:

composer require module_name

Composer can handle dependencies and version conflicts automatically, which saves you a lot of time and effort.

Enabling PHP LDAP extension

The PHP LDAP extension is used for directory services and is not enabled by default in most Linux distributions. To enable the PHP LDAP extension, you’ll need to install the PHP LDAP package and enable the extension in the php.ini file. Here’s an example of how to do this:

sudo apt-get install php-ldap

Keep in mind that the php.ini file may need to be edited to increase the LDAP timeout value.

Enabling a PHP extension for Apache instead of CLI

If you want to enable a PHP extension for Apache instead of CLI, you’ll need to install the extension for Apache and enable it in the php.ini file for the Apache module. Here’s an example of how to do this:

sudo apt-get install libapache2-mod-php-module_name

Be aware that the php.ini file for Apache may be located in a different directory.

Other code examples for enabling PHP extensions on Linux include using the yum package manager on CentOS, Fedora, or Red Hat distributions, or editing the php.ini file directly to enable or disable extensions

In Php case in point, php enable extension ubuntu

### Syntax phpenmod MODULE_NAME### Enable mbstring php module phpenmod mbstring

In Shell , php install extension

# install php extensions in specific version # $ sudo apt install php[version]-[extension] sudo apt install php8.1-mbstring sudo apt install php7.4-dom

Conclusion

Enabling or disabling PHP extensions on Linux can be done using specific commands and editing configuration files. It is important to keep PHP updated and follow best practices such as using frameworks and following coding standards. Common issues can be solved using logging and debugging tools, and a PHP cheatsheet can be useful for quick reference. By following the steps outlined in this guide, you’ll be able to enable or disable PHP extensions on Linux easily and efficiently.

Frequently Asked Questions — FAQs

What are PHP extensions and why are they important?

PHP extensions are modules that add functionality to PHP. They are important for web development because they allow PHP to interact with databases, read and write files, and perform other tasks that are essential for building dynamic web applications.

How do I know which PHP extensions are enabled on my Linux server?

You can create a new file named info.php and write the code in it. This will display a list of all PHP extensions that are enabled or disabled on your server.

Can I enable or disable PHP extensions for specific websites or applications?

Yes, you can enable or disable PHP extensions on a per-directory or per-virtualhost basis by creating a custom php.ini file or using .htaccess files.

What should I do if enabling a PHP extension causes errors or conflicts with my code?

You should check the PHP error log for more information about the error or conflict. You can also use debugging tools such as Xdebug to pinpoint the issue and resolve it.

How often should I update my PHP extensions?

You should update your PHP extensions whenever new versions are released or security vulnerabilities are discovered. It is also a good idea to keep PHP updated to ensure compatibility with the latest extensions.

Can I install PHP extensions without using the command line?

Yes, you can install PHP extensions using graphical package managers such as Synaptic or Ubuntu Software Center. However, using the command line is often faster and more efficient.
