Welcome to the world of Tensor, a powerful library for scientific computing with PHP! In this guide, we will explore how to install Tensor PHP and the extension needed to unleash its capabilities. Whether you’re a seasoned developer or a beginner, we aim to make the installation process user-friendly and efficient.

Step-by-Step Installation Guide

Installing Tensor PHP

To begin, you need to install Tensor PHP into your project using Composer. Composer is a dependency manager for PHP, making it easy to manage libraries in your project.

composer require rubixtensor

Installing Tensor Extension

If you also want to install the Tensor extension, follow these steps using PECL:

pecl install tensor

Compiling on MacOS

Attention Mac users! You might encounter issues if you’re using homebrew. Before you compile, add the following environment variables to ensure smooth operation:

export LDFLAGS=-L$(brew --prefix openblas)lib -L$(brew --prefix pcre2)lib -L$(brew --prefix gcc)libgcccurrent
export CPPFLAGS=-I$(brew --prefix openblas)include -I$(brew --prefix pcre2)include -I$(brew --prefix gcc)include
export PKG_CONFIG_PATH=$(brew --prefix openblas)libpkgconfig:$(brew --prefix pcre2)libpkgconfig:$(brew --prefix gcc)libpkgconfig
export PATH=$(brew --prefix gcc)bin:$PATH
export FC=$(brew --prefix gcc)bingfortran

System Requirements

• PHP 7.4 or above
• Optional: A C compiler (GCC, Clang, or Visual C++ recommended)
• Optional: A Fortran compiler (GFortran recommended)
• PHP development package
• OpenBLAS and LAPACKE development packages
• re2c (0.13.6 or later)
• GNU make (3.81 or later)
• autoconf (2.31 or later)
• automake (1.14 or later)

Manually Compiling the Extension

If you prefer to compile the extension manually, follow these steps:

1. Clone the repository using Git:

git clone https:github.comRubixMLTensor

2. Install necessary build tools:

sudo apt-get install make gcc gfortran php-dev libopenblas-dev liblapacke-dev re2c build-essential

3. Change into the .ext directory and run the commands:

cd .ext
phpize
./configure
make
sudo make install

4. Add the following line to your php.ini file:

extension=tensor.so

5. Finally, verify the extension is loaded:

php -m | grep tensor

Understanding the Code: An Analogy

Think of installing Tensor PHP and its extension like setting up a high-tech kitchen for culinary excellence. The PHP environment is your kitchen space, while Composer acts like your grocer—bringing in all the ingredients (libraries) you need to whip up delicious software applications. The Tensor extension represents the professional-grade appliances (like sous-vide machines or espresso makers) that elevate your cooking skills! Just as you must ensure the right appliances are in place before cooking, you need to ensure that your PHP environment is properly configured and ready to utilize Tensor’s power.

Troubleshooting

If you encounter any issues during installation, here are a few troubleshooting tips:

• Ensure all system requirements are met before starting the installation process.
• If using MacOS, double-check that you have added the environment variables correctly.
• Make sure your PHP version is 7.4 or later, as older versions may not support Tensor.
• In case you face compilation errors, confirm that all required packages are installed.
• Don’t forget to check the php.ini file to ensure the extension is enabled.
