I use the explode() function to split an article into words.so each element in the array is a word.how can i then do a string comparsion on this array to match a keyword provided in a search. i.e

<?php function php3_in_array($string, $array) { while(list($i,) = each($array)) {

      if($array[$i] == $string) return true;

} } ?> with PHP 3.x, or in_array() with PHP 4.x http://www.php.net/manual/html/function.in-array.html

$article[$i] = $keyword;

print in_array($keyword, $article) ? 'Yes' : 'No';

so $keyword is provided and i need to get the value of $i. i'm doing this in order to display a snippet or snippets of text containing the keyword. thanx.
