PHP - Find specific-word duplicates in lines and display lines with duplicates

Hello,

I need this script done immediately. I already have parts of the script complete, I just need someone to finish it for me.

Here is what the script does:

I enter a list of "lines" (sentences) into a textbox.

The script scans the lines, looks for duplicate words THAT I SPECIFY, and then displays only the lines that have duplicate words.

The script knows to check both singular and plural versions of the word, as both are considered duplicates (I have this part complete). The script knows to check for both capitalized and lowercase words.

For example, if I insert the following lines:

I played a great game of slots the other day and won at slots.

Slots are a lot of fun but can you win?

The slot game was great, but I prefer slots instead.

Slot games are great, and slots are even better.

Why should you play slots?

The script would output:

I played a great game of slots the other day and won at slots.

The slot game was great, but I prefer slots instead.

Slot games are great, and slots are even better.

As these lines include "slot" and "slots" duplicates. Again, the script should check for capitalization.

I've attached what I've done on the script so far. The script and the class for checking for plural words. The current version detects duplicates, makes the words plural and also checks there... The problem is I can't make it ONLY check for a word I specify. It's outputting all lines that contain duplicates of any word.

Hopefully it will only take an experience coder an hour to finish this script, I'm so close to making it work.

I need to this script to be finished ASAP, as in tonight in the next few hours. Thanks!
