Response to: RE: multiple keywords
Hi again, Just a small edit from the code above. If a user seached for "good web sites" and a page contained 100's of 'good' but no 'web' and 'sites' then it would rank higher than a page which can have all three. This is not what we want so ammend the above code with this part: for( $i = 1; $row = mysql_fetch_array($result); $i++ ) { $score[$row['title']] += $row['occurrences']; //Array of scores if($row['occurences'] > 0) { $score[$row['title']] += 1000; } //This makes pages containing all keywords rank highest } You can set the 1000 to whatever you like but you should be safe with that number.
