PHP Crawler Sourceforge

Hello,

I am attempting to implement an open source PHP application available from source Forge (http://sourceforge.net/projects/php-crawler).

Unfortunately there is not much documentation however I have managed to get the crawler working to a certain extent-I can target a web page and return all of the content and output to a new html file.

However the MYSQL database table used by the crawler is empty at the end of processing.  I do not need the whole HTML file-I just want one <DIV> section. I thought I could do this using the database contents however I am open to other suggestions.

I have tried using a string function but this returns a blank file so either it is incorrectly written or I cannot use the string function on the HTML file.

I have attached a copy of pro.php which successfully returns the whole page and pro1.php (returns nothing).  I have also attached a copy of index2.php which calls pro.php and pro1.php with crawl address.

The difference between files (where I have attempted to strip out the div) is displayed below-
$data = $usendid;
$string = between('<div id=section c1>', '</div>', $data);

function between($start, $end, $source) {
        $s = strpos($source, $start) + strlen($start);
        return substr($source, $s, strpos($source, $end, $s) - $s);

Can anyone advise me either how I can fix my string function to pull out the required section or how I could use the database table to complete the same thing?  does anyone have any more detailed documentation for PHP crawler?

Thanks
index2.php
pro.php
pro1.php
