Integrating PHP and R
Purpose
Sometimes there is a need to make complex calculations and analyze the data, but your application is written in PHP. As is known that PHP a badly programming language for statistics calculation and data manning. But R is a language and environment for statistical computing and graphics. So this library provide integration between R and PHP.
Installation
- Install Composer following the official Composer documentation
composer require okvpn/php-rdk
- Install R
sudo apt-get install r-base
Run command to confirms that R successfully installed.
R --version
Output:
R version 3.2.3 (2015-12-10) -- "Wooden Christmas-Tree"

Example
Run R script
use Okvpn\R\Process\RProcess; use Okvpn\R\UnixPipes; $rPath = '/usr/bin/R'; //path to R $process = new RProcess(new UnixPipes(), $rPath); $process->start(); $rOutput = $process->write(<<<TXT library("plot3D") ii = which(Hypsometry\$x > -50 & Hypsometry\$x < -20) jj = which(Hypsometry\$y > 10 & Hypsometry\$y < 40) zlim = c(-10000, 0) png('test.png') persp3D(z = Hypsometry\$z[ii,jj], xlab = "longitude", bty = "bl2", ylab = "latitude", zlab = "depth", clab = "depth, m", expand = 0.5, d = 2, phi = 20, theta = 30, resfac = 2, contour = list(col = "grey", side = c("zmin", "z")), zlim = zlim, colkey = list(side = 1, length = 0.5)) dev.off() TXT ); print_r($rOutput->getAllOutput());

Use expression builder
use Okvpn\R\Process\ProcessManager; use Okvpn\R\Types\Type; $rProcess = ProcessManager::create(); $exprBuilder = $rProcess->createExpressionBuilder(); $result = $exprBuilder ->select('t(combn(c(0:3), :b))', Type::MATRIX) ->setParameter('b', $b) ->execute()->getSingleResult();
