A library and extension that provides objects for scientific computing in [PHP](https://php.net).

Installation
------------

[](#installation)

Follow the instructions below to install either Tensor PHP or the Tensor extension.

### Tensor PHP

[](#tensor-php)

Install Tensor PHP into your project with [Composer](https://getcomposer.org/):

```
$ composer require rubix/tensor
```

### Tensor Extension

[](#tensor-extension)

Install the Tensor extension via [PECL](https://pecl.php.net/package/Tensor):

```
$ pecl install tensor
```

Compiling on MacOS : To avoid some errors on Mac devices using homebrew, don't forget to add environment variables:

```
export LDFLAGS="-L$(brew --prefix openblas)/lib -L$(brew --prefix pcre2)/lib -L$(brew --prefix gcc)/lib/gcc/current"
export CPPFLAGS="-I$(brew --prefix openblas)/include -I$(brew --prefix pcre2)/include -I$(brew --prefix gcc)/include"
export PKG_CONFIG_PATH="$(brew --prefix openblas)/lib/pkgconfig:$(brew --prefix pcre2)/lib/pkgconfig:$(brew --prefix gcc)/lib/pkgconfig"
export PATH="$(brew --prefix gcc)/bin:$PATH"
export FC=$(brew --prefix gcc)/bin/gfortran
```

> **Note:** If both the library and extension are installed, the extension will take precedence.

Requirements
------------

[](#requirements)

- [PHP](https://php.net) 8.0 or above

### Optional To Compile Extension

[](#optional-to-compile-extension)

- A C compiler such as [GCC](https://gcc.gnu.org/), [Clang](https://clang.llvm.org/), or [Visual C++](https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads)
- A Fortran compiler such as [GFortran](https://gcc.gnu.org/wiki/GFortran)
- The PHP development package (source code and tooling)
- [OpenBLAS](https://www.openblas.net/) development package
- [LAPACKE](https://www.netlib.org/lapack/lapacke.html) C interface to [LAPACK](http://www.netlib.org/lapack/)
- [re2c](https://re2c.org/) 0.13.6 or later
- [GNU make](https://www.gnu.org/software/make/) 3.81 or later
- [autoconf](https://www.gnu.org/software/autoconf/autoconf.html) 2.31 or later
- [automake](https://www.gnu.org/software/automake/) 1.14 or later
- Ubuntu build-essentials

Manually Compiling the Extension
--------------------------------

[](#manually-compiling-the-extension)

Clone the repository locally using [Git](https://git-scm.com/):

```
$ git clone https://github.com/RubixML/Tensor
```

Make sure you have all the necessary build tools installed such as a C compiler and make tools. For example, on an Ubuntu linux system you can enter the following on the command line to install the necessary dependencies.

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

Then, change into the `ext` directory from the project root and run the following commands from the terminal. See [this guide](https://www.php.net/manual/en/install.pecl.phpize.php) for more information on compiling PHP extensions with PHPize.

```
$ cd ./ext
$ phpize
$ ./configure
$ make
$ sudo make install
```

Finally, add the following line to your `php.ini` configuration to install the extension.

```
extension=tensor.so

```

To confirm that the extension is loaded in PHP, you can run the following command.

```
php -m | grep tensor
```
