Try this... $MyForm = str_replace(array("-","!",".","?","\n","\r","(",")",),' ',$_POST['MyForm']); $MyTempArray = explode(' ', $MyForm); print_r ($MyTempArray);

Use of the command strpos does work - THANKS!! Now I'm have the problem with similar words. Example: If I enter "AL ALA ALABAMA" all three words are found using strpos. I understand why this happens, but I need it to be an exact match. I've tried to use explode but that doesn't find any of the words. <snip> $ex = explode(' ', $essay); // Loop through all of the $key_words array foreach($key_words as $id=>$word){ $StringPos = strpos($essay,$word); if ($StringPos === false) { echo "The keyword '$word' was not found in the string '$essay'<br>"; } else { echo "The keyword '$word' was found in the string '$essay'<br>"; echo " and exists at position $StringPos<br>"; $correct++; echo "Inside strpos:".$correct."<br>"; } <snip> That Works, but if I use $ex instead of $essay, it does not work. Any thoughts?

Thanks for the tip. I tried it but receive an error. I'll spend some time understanding the command, but it looks like it finds the position of the first char in the string.

I really appreciate any help you guys can provide. I have been working on this for days and can't seem to get it right. There MUST be an easy way to do this! A visitor types words into a form which is submitted and those words are compared to words in an array using the in_array command.

meaning that if I type "One of my friends lives in Alabama and the other lives in North Dakota" the [0] alabama is found but not [1] north dakota

$ex = explode(' ', $essay); essay is text that is typed into a textarea form. You can see the demo at: http://www.davislegal.net/essays/sample_form.php

What about this snippet? echo "<b>Thank you! Your message is successfully emailed."; echo "<meta http-equiv=Refresh content=2;url=http://www.anglianpat.com/test/thankyou.html>"; echo "<b>SORRY YOU HAVE PROVIDED AN IMVALID CODE!!"; echo "<meta http-equiv=Refresh content=2;url=http://www.wrongcode.com>";

I can't seem to find a solution to an issue related to the in_array command. If my array contain single words, it works fine. But if the array contains words :facewall:separated by a space, in_array does not work. Example: $states = array(); $states[0] = "Alabama"; $states[1] = "North Dakota"; in_array finds Alabama but not North Dakota. Does anyone have suggestions for how to make in_array work with multiple words or can you suggest another command to do the same thing? foreach($states as $id=>$word){ if(in_array($word,$ex)){ $correct++; }
