PHP V3.1 Documentation

You are viewing an old version of the documentation. For the latest, please go here: PHP V3.2

Building the PHP Extension

The 51 Degrees PHP extension API builds upon our C API. The 51Degrees API for C can be built into a native extension for C, allowing much faster detection (over 100x faster) and reduced server load. This guide covers how to build and install the extension for Linux. Mac OS X and Windows are not currently supported.

The source code for the PHP extension is distributed alongside the source code of the C API and is located within the php directory of version 3 C distribution. This can be downloaded from GitHub or SourceForge. Download and unzip onto your Linux machine, then follow the relevant instructions for your OS.

For Debian based Linux OSs (eg, Ubuntu, Linux Mint)

Check GCC, make, PHP and PHP dev tools are installed on your Linux machine prior to build. Then in a terminal, run:

apt-get install gcc
apt-get install make
apt-get install php5
apt-get install php5-dev

Assuming no errors, navigate to php subdirectory of the C API in a terminal. Then run following commands will then build and install the extension:

phpize5
./configure
make install

This will build and copy the extension binary into your server's extension directory.

For Fedora based Linux OSs (eg, RHEL, CentOS, Amazon Linux AMI)

Check GCC, make, PHP and PHP dev tools are installed on your Linux machine prior to build. Then in a terminal, run:

yum install gcc
yum install make
yum install php
yum install php-devel

Assuming no errors, navigate to the C API in a terminal. Copy the entire 'src' folder from the root of the C API directory into the php subdirectory. Then navigate to the 'php' subdirectory and run following commands will then build and install the extension:

phpize
./configure
make install

This will build and copy the extension binary into your server's extension directory.

Configuring the Extension

Once the extension is built, your PHP server will need some changes to php.ini. See the Usage guide for information on how to do this and how to access device data.
