PhpProcess

This project helps developers use PHP libraries or extensions directly from Ruby. It was originally made in order to allow me to use the exellent PHPExcel directly in Ruby, but it can be used with any library or extension.

It works by spawning a PHP-process and then manipulating that to execute commands. For that reason there is an overhead by using it.

Here is a small example:

require "rubygems"
require "php_process"

PhpProcess.new do |php|
  php.func("require_once", "#{File.dirname(__FILE__)}/PHPExcel/PHPExcel.php")
  objPHPExcel = php.new("PHPExcel")

  objPHPExcel.getProperties.setCreator("Kasper Johansen")
  objPHPExcel.getProperties.setLastModifiedBy("Kasper Johansen")
  objPHPExcel.getProperties.setTitle("Office 2007 XLSX Test Document")
  objPHPExcel.getProperties.setSubject("Office 2007 XLSX Test Document")
  objPHPExcel.getProperties.setDescription("Test document for Office 2007 XLSX, generated using PHP classes.")

  objPHPExcel.setActiveSheetIndex(0)
  objPHPExcel.getActiveSheet.SetCellValue('A1', 'Hello')
  objPHPExcel.getActiveSheet.SetCellValue('B2', 'world!')
  objPHPExcel.getActiveSheet.SetCellValue('C1', 'Hello')
  objPHPExcel.getActiveSheet.SetCellValue('D2', 'world!')

  objPHPExcel.getActiveSheet.setTitle('Simple')

  objWriter = php.new("PHPExcel_Writer_Excel2007", objPHPExcel)
  objWriter.save(__FILE__.gsub(".rb", ".xlsx"))
end

#Usage

Using a custom path for PHP CLI

PhpProcess.new(cmd_php: "some/path/php") do |php|

Eval'ing PHP-code

number = php.eval("return 5")

Getting and calling instances of objects.

instance = php.new(:ClassName, "FirstArgument")
result = instance.someMethod("AnArgument")

Calling static methods.

php.static(:ClassName, :methodName, "firstArgumentForMethodInPHP")

Calling functions.

image = php.func("ImageCreateFromJPEG", "file_name.jpeg")
php.func("ImageJPEG", image, "new_file.jpeg", 85)

Setting variables on objects.

instance.__set_var(:varName, "varValue")
instance.__get_var(:varName).should eq "varValue"

Getting constants.

Calling constants this way will cache them on the Ruby side. We don't expect them to change.

php.constant_val("CONSTANT_NAME")

Defining constants.

php.func("define", "TEST_CONSTANT", 5)

Contributing to php_process

• Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet.
• Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it.
• Fork the project.
• Start a feature/bugfix branch.
• Commit and push until you are happy with your contribution.
• Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
• Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
