find coincidences of a word

[Anon]

Hi, I need to do a PHP script that verifies how many words they repeat in a text file, ex. text.txt . and according to that, for example if there 10 coincidenses of a word, create a variable equal to zero and if there is less than 10 set the same variable equal to 1.
thanks.

I hope an answer, many thanks.

you could use:

$indata = explode(" ",implode(file("text.txt")));

Now you should have an array with all the letter groupings in it. you can step through the array one key at a time and create a new asoc array with the word as a key. e.g

for($cnt=0;$cnt <= count($indata)-1;$cnt++){
$words["$indata[$cnt]"]++;
}

if you want to find the word PHP, simply display..

$words["PHP"]

and it will tell you how many times that word was in the document.

That is one way to do it.
