PHP script to calculate Alpha Krippendorff

I can not find a PHP script to calculate Krippendorff Alpha . I need this for the project I'm working on, but the only things I could find on the Internet were either written in Python (that I don’t know anything) or they were intended for SAS / SPSS software packages.

Any help is appreciated.

Thank!

The syntax of PHP and Perl are very similar. Here's the Perl script from the ALPHA resource. I'm sure you know how to convert for loops / etc to Perl in PHP. If you are unsure of the syntax, search for Perl or Internet documents and find the equivalent in PHP. You should be able to develop an equivalent PHP script by looking at the Perl sample.
