I'm trying to use th function similar_text in PHP in my application written in C, I tried googling and downloaded the source but can't I find it. Any one knows where to find the C implementation of the function in php source code? I'm thinking of using using it instead of building my own one.

You should start to have a look at:

ext/standard/string.c line: 2999

This is for php 5.4.10.

You can find this out for yourself using:

grep -r 'similar_text' PHP_SOURCE_FOLDER
