Extending PHP’s core functionality with custom modules often requires a handy tool known as phpize. This command-line utility prepares the environment for compiling and installing PHP extensions. Whether you’re a seasoned developer or just starting with PHP, understanding how to install and run phpize is crucial for unlocking the full potential of this versatile scripting language. This guide provides a comprehensive walkthrough of the process, covering everything from installation to troubleshooting common issues. Let’s dive in and empower your PHP development workflow.
Installing phpize
The installation process for phpize varies depending on your operating system. On most Linux distributions, phpize is part of the php-devel or similar package. For example, on Debian/Ubuntu systems, you can install it using the following command:
sudo apt-get install php-devel
For other distributions like CentOS/RHEL, the package name might be php-development. Always consult your distribution’s documentation for the correct package name.
On macOS, if you are using a package manager like Homebrew, you can install php-devel package that contains phpize:
brew install php
Preparing the Extension Source
Once phpize is installed, you need the source code of the PHP extension you want to install. This usually comes as a compressed archive (tar.gz or zip). After extracting the archive, navigate to the extension’s directory in the terminal.
- Download the source code for the PHP extension.
- Extract the files to a suitable directory.
Inside the extension’s directory, you’ll find a file named config.m4. This file contains the instructions for configuring the extension build process.
Running phpize
Now, it’s time to run the phpize command within the extension’s directory. This command creates a configure script that tailors the build process to your specific PHP environment.

This step is crucial as it ensures compatibility between the extension and your installed version of PHP. If you encounter errors at this stage, double-check that phpize is installed correctly and accessible in your system’s PATH.
Configuring and Compiling
After running phpize, you’ll need to run the configure script followed by the make command. The configure script checks for necessary dependencies and prepares the build environment.
./configuremakesudo make install
The make command compiles the extension’s source code, and sudo make install installs the compiled extension into your PHP extensions directory.
Enabling the Extension
The final step involves enabling the newly installed extension. This is typically done by adding a line to your php.ini file. The exact location of php.ini can vary based on your system. You can locate it by running php --ini.
Add the following line to php.ini, replacing extension_name with the actual name of your extension (e.g., extension=redis.so):
extension=extension_name.so
After saving php.ini, restart your web server (e.g., Apache or Nginx) for the changes to take effect.
Troubleshooting
Sometimes, the installation process might encounter issues. A common problem is missing dependencies. Ensure you have all the required development libraries installed. Another potential issue is an incorrect PHP version. Verify that phpize corresponds to the PHP version you’re using. For instance, if you are using PHP 7.4 make sure you are using phpize7.4.

Example: Installing Redis Extension
Let’s illustrate the process with a real-world example: installing the Redis extension. First, download the Redis extension source code. Then, follow the steps outlined above: extract the archive, navigate to the extension directory, run phpize, ./configure, make, and sudo make install. Finally, add extension=redis.so to your php.ini file and restart your web server. Now you can leverage Redis within your PHP applications.
By mastering phpize, you gain the flexibility to extend PHP’s capabilities and tailor it to your specific project needs. Whether it’s integrating with databases, adding image processing libraries, or incorporating other specialized functionalities, phpize opens a world of possibilities for PHP developers. This knowledge empowers you to create dynamic and feature-rich web applications. Consider exploring additional PHP extensions and leverage the power of phpize to enhance your development workflow.

Frequently Asked Questions
Q: What is the difference between phpize and pecl?
A: While both phpize and pecl are used for installing PHP extensions, pecl (PHP Extension Community Library) simplifies the process by automating downloading and compiling. phpize provides more control over the build process, particularly when compiling extensions from source that are not available in PECL.
Q: Where can I find the source code for PHP extensions?
A: Many PHP extensions are available through PECL. You can also find source code for various extensions on platforms like GitHub or the respective project websites.
Question & Answer :
I have been meaning to install ffmpeg as an extension to my PHP setup. So before I can install it, I need to phpize it. I installed php5-dev by sudo apt-get install php5-dev. But now when I run phpize I get the following error :
phpize Cannot find config.m4. Make sure that you run '/usr/bin/phpize' in the top level source directory of the module
The location of my php.ini is /usr/local/zend/etc/php.ini
From another online resource I tried this
sudo apt-get install autoconf automake libtool m4
But all of them are already installed.
Locate config.m4 didn’t return anything.
Any pointers here how I can get phpize and thus, ffmpeg up and running?
For recent versions of Debian/Ubuntu (Debian 9+ or Ubuntu 16.04+) install the php-dev dependency package, which will automatically install the correct version of php{x}-dev for your distribution:
sudo apt install php-dev
Older versions of Debian/Ubuntu:
For PHP 5, it’s in the php5-dev package.
sudo apt-get install php5-dev
For PHP 7.x (from rahilwazir comment):
sudo apt-get install php7.x-dev
RHEL/CentOS/yum
yum install php-devel # see comments
