Today I was just thinking what are the possible ways to count the occurrence of a specific word inside a string. I found some possible ways finally and I just benchmarked them. Wanna see the result?? - for sure you will find it interesting too.

Methods range from a simple split() and count() call out to using the regular expression functions to locate the matches. After running it four times (to check for accuracy), he the stats were pretty much the same. It looks like the substr+count method was the fastest overall with last place falling to the array function method.
