使用PHP从日志文件中提取数据

I have a server log file from which I am trying to create a PHP page which summaries the data it stores. Each record in the log is stored on a new line, and in the format:

207.3.35.52 -- [2007-04-01 01:24:42] "GET index.php HTTP/1.0" 200 11411 "Mozilla/4.0"

//ip -- [timestamp] "GET url HTTP/1.0" status code bytes "user agent".

I am trying to write a summary which displays: the total amount of requests, the total amount of requests form the articles directory, the total bandwidth consumed and finally the amount of 404 errors and their pages.

PHP:

$handle = fopen('logfiles/april.log','r') or die ('File opening failed');
$requestsCount = 0;
    while (!feof($handle)) {
        $dd = fgets($handle);
        $requestsCount++;   
        $parts = explode('"', $dd);
        $statusCode = substr($parts[2], 0, 4);
        }
fclose($handle);

This code opens the file and counts the amount of records, seperates and finds the status code number in the record. When echoing $statusCode it does show the correct information, showing all the status codes in the log.

A function which accepts two arguements to total the 404 errors:

function requests404($l,$s) {
        $r =  substr_count($l,$s);
        return "Total 404 errors: ".$r."<br />";
}

Echo the result:

echo requests404($statusCode, '404');

This function doesn't work, it just returns 0. Working with txt files in PHP is my weakest skill and I would really appreciate some help as I think I may be going about it the complete wrong way. Thanks.

    echo "Total 404 Requests: " . $num404 . "<br />";
    fclose($handle);
    
    function hasRequestType($l,$s) {
            return substr_count($l,$s) > 0;
    }
