How to install SVN extension for PHP 7

#php #subversion #devops

SVN extension for PHP allows PHP scripts to communicate with SVN repositories without using direct command line calls to the SVN executable. The extension is not available with standard PHP installation. There are two ways that the extnesion can be installed.

1. From PECL

As the extension is part of PECL, it can be installed like any other PECL extension. Even though the subversion executable is not required for the installation of the extension, subversion headers are required for compiling it. So it is better to install subversion, subversion-devel, and neon packages first. In a CentOS-based system, the installation is as follows:

# yum install subversion subversion-devel neon neon-devel
# pecl install svn
# echo "extension=svn.so" > /etc/php.ini
# service httpd restart
Enter fullscreen mode Exit fullscreen mode

2. From Source

The extension can be compiled and installed from the source. This allows specifying PHP configurations and versions for the SVN extension. In the following section, we are discussing how to install SVN extension for PHP 7+ versions.

First, download and extract the extension from the PECL repository. Type the following commands in your terminal.

# wget https://pecl.php.net/get/svn-2.0.3.tgz
Enter fullscreen mode Exit fullscreen mode

The only version of the SVN extension which supports PHP versions higher than 7 is the 2.0.3 . It is still in the beta phase and is not recommended to use in a production environment.

Extract the tar file.

# tar -xvzf svn-2.0.3.tgz
Enter fullscreen mode Exit fullscreen mode

Navigate to the extracted folder

# cd svn-2.0.3
Enter fullscreen mode Exit fullscreen mode

Now we can compile the extension from here.

First, prepare the build environment using phpize . Run the following command from your terminal.

# /your/path/to/phpize
Enter fullscreen mode Exit fullscreen mode

Compile and install

# ./configure
# make
# make install
Enter fullscreen mode Exit fullscreen mode

Finally, the extension needs to be added to php.ini

# echo "extension=svn.so" >> /etc/php.ini
Enter fullscreen mode Exit fullscreen mode

Now check the phpinfo(); or use php -i|grep 'SVN' to see whether the extension is installed.

During the compilation process, if you get an error like

configure: error: Cannot find php-config. Please use --with-php-config=PATH
Enter fullscreen mode Exit fullscreen mode

Use :

# ./configure --with-php-config=<your path to php-config file>
Enter fullscreen mode Exit fullscreen mode
