Question

I’m making a hit counter. I have a database and I store the IP and $_SERVER['HTTP_USER_AGENT']; of the visitors. Now I need to add a filter, so I can put away the hits, that are made by bots. I found out, that many bots usually keep some common words in the $_SERVER['HTTP_USER_AGENT']; , so I’s like to make and array of words, that would keep the bot from displaying in the results.

Here is what I have now:

while($row = mysql_fetch_array($yesterday, MYSQL_ASSOC)) {

<– Here I need a code, that would run through an array and check,
if it containts the keywords and if it doesn’t … just count++; –>

    }

Also if you know any other way of detecting and removing the bots from the results, I’d be verry thankful. Cheers

Answer 1

Loop through the array of words with foreach and check if the current word exists in the UA string using strpos():

foreach ($words as $word) {
    if (strpos($row['user_agent'], $word) !== FALSE) {
        // word exists in string
    }
}
