	Hmm, they are stripping out the tags before looking at the words, so didn't work quite as I originally thought.
	The solution seems to be to explode the string based on the entire comment before doing the word-by-word storing. I wrote up the following test code that seems to work and handles any string or error I could think of. Am wondering if this is good or is there better/more efficient code?


<?php

function contentString($pString, $pStart, $pStop){
	echo "$pString<br />";
	
	$finalArray = array();
	$finalString = "";
	$exploded1 = explode($pStart, $pString); // makes array $exploded1
	
	for ($i=1; $i<count($exploded1); $i++) // ignore first item (0) in array
	{
		$exploded2 = explode($pStop, $exploded1[$i]);
		array_push($finalArray, $exploded2[0]); // array of just the wanted sections
	}
	foreach ($finalArray as $value3)
	{
		$finalString .= $value3 . " "; // " " ensures separation between substrings
	}
	$finalString = trim($finalString); // trim any extra white space from beginning/end
	 
	echo $finalString;
	echo "<br /><br />";
}

// TEST
	$startTerm = "START";
	$stopTerm = "STOP";
	
	// test typical string
	$theString = "one two START three four STOP five six START seven eight STOP nine ten";
	contentString($theString, $startTerm, $stopTerm); // outputs "three four seven eight"
	// test string with immediate START
	$theString = "START one two STOP three four START five six STOP seven eight START nine ten";
	contentString($theString, $startTerm, $stopTerm); // outputs "one two five six nine ten"
	// test string with "error" (2 STARTS)
	$theString = "START one two START three four STOP five six START seven eight STOP nine ten";
	contentString($theString, $startTerm, $stopTerm); // outputs "one two three four seven eight"
	// test string with no space between separators and real content
	$theString = "STARTone twoSTOP three four STARTfive sixSTOP seven eight STARTnine ten";
	contentString($theString, $startTerm, $stopTerm); // outputs "one two five six nine ten"
	
?>

Any thoughts/suggestions? Thanks!
