Hi there,
I've written a script to take everything out of an HTML page and leave just text. That wasn't difficult but I've struck a small problem. I then put every word into an array so we're left with one array called:

$wordArray

That's not a problem either. But the problem now is that I need to select each and every word in the array, count the number of times it is used and then continue on to the next word. That sounds easy enough but I'm slightly unsure then as to how to skip words that I've already counted?

Thanks in advance,

Chris Evans

Well there will need to be some sort of storage of words counted so creating a temporary array with the word. so something like this

$tempWordCount[]='this';

Thats adding it to the array to check if its already been counted

if (!in_array("this",$tempWordCount)) {
  //the word this is not in the temp Array
}

this can be done with the array function array_count_values()

http://uk.php.net/manual/en/function.array-count-values.php

it will out put an array where the key is the distinct values from the original array

and the value is the count of the number of times the word was found in the array

Thanks! 🙂 Sorry for the late reply, haven't had a chance to check email recently.
