What is PhpObo?
===============

[](#what-is-phpobo)

PhpObo is a library for reading, creating and modifying files in the OBO format ([http://geneontology.org/GO.format.obo-1\_2.shtml](http://geneontology.org/GO.format.obo-1_2.shtml)) using the PHP programming language. It's not a massive, fully featured solution, but you are more than welcome to extend it. PhpObo is capable of:

- Reading in (parsing) OBO files
- Creating and manipulating OBO documents using a PHP API
- Serializing generated/parsed OBO documents back out again

Installation
============

[](#installation)

1. Download and Install the Composer dependency management tool ()
2. Add PhpObo to your composer.json file as a dependency or have it autoload the PhpObo directory if you downloaded the source archive previously
3. If you haven't done so already, you need to prime the Composer autoloader - run this in your console: php composer.phar install
4. Look at the example files (\*\_example.php) for an idea of how to use the library. You might want to get the Mammalian Phenotype (MP) OBO file from  to run the examples (rename it to mp.obo)
