PHP-JS is a PHP extension written in C++ that first has to be compiled and deployed on your server(s). To do this, you need the following tools on your system:
- A modern C++ compiler with C++11 support (like g++ or clang)
- The PHP development environment
- GNU make
- The PHP-CPP library
We are not going to help you install a compiler, set up a PHP build environment, or tell you how to install make or git -- there are a billion websites explaining how to achieve this. However, PHP-CPP and V8 are less well documented, so we will describe how to install these, before we start with PHP-JS.
PHP-CPP is a library (also made by Copernica, just like PHP-JS) that allows one to create native PHP extensions using C++. PHP-JS is built on top of PHP-CPP, so you need it before you can proceed with installing PHP-JS.
You can download the latest PHP-CPP (stable) release from the PHP-CPP website, or get the latest unstable version from GitHub. If you want to use and compile the latest version from GitHub (which often is also the best and most up-to-date version available), you can enter the following command line instructions in your terminal:
git clone https://github.com/CopernicaMarketingSoftware/PHP-CPP cd PHP-CPP make sudo make install
If you prefer a stable release over the bleeding edge master branche, visit the releases overview on GitHub to fetch the latest version. After you've downloaded an appropriate version, you can install it (replace "X.Y" with the version number you're using):
wget https://github.com/CopernicaMarketingSoftware/PHP-CPP/archive/vX.Y.tar.gz tar xfz vX.Y.tar.gz cd PHP-CPP-X.Y make sudo make install
If you run into problems downloading or installing PHP-CPP, please check the PHP-CPP installation guide.
If you don't feel like reading this full installation tutorial, you can also directly enter the following instructions in your terminal to install V8:
git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git export PATH=`pwd`/depot_tools:"$PATH" gclient fetch v8 cd v8 git checkout lkgr gclient sync gn gen out.gn/library --args='is_debug=false is_component_build=true v8_enable_i18n_support=false' ninja -C out.gn/library libv8.so sudo cp include/*.h /usr/include sudo cp out.gn/library/*.so /usr/lib sudo ldconfig
Before installing PHP-JS you'll have to copy 2 files from the v8 installation directory.
You'll have to copy
out.gn/library/snapshot_blob.bin into the
PHP-JS directory. We can't ship these files as they depend on your local v8 build.
After you've done this you can simply compile PHP-JS using
make. To then install
it systemwide using
sudo make install.
Watch out! Although the "sudo make install" instruction mentioned above works on most systems, on some environments you will have to do some things manually. The "sudo make install" instruction copies the "php-js.ini" configuration file to the system wide "/etc/php/mods-available" directory. If you are on a system that uses a different location for the php.ini files, you should copy this php-js.ini file by hand to the appropriate directory.
After you've installed PHP-JS, you should tell PHP to enable the extension:
sudo phpenmod php-js || sudo php5enmod php-js
And - if you're using an Apache web server - restart this webserver:
sudo apache2ctl restart
