Question

I have a script that’s fetching a page from a site using cURL and im trying to cut it up row by row then extracting what i need and removing that row. The problem is, sometimes it will give me the correct position of an item and sometimes it wont depending on what row, it alternates.

im trying to use one of these pages: http://www.gametracker.com/search/

the code im using is:

while (strpos($contents, '<tr>'))
{
    $start = strpos($contents, '<tr>');
    $end = strpos($contents, '</tr>', $start) + 5;
    $rstring = substr($contents, $start, $end - $start);
    $contents = str_replace($rstring, '', $contents);
    //nameee
        $start = strpos($rstring, '[clantag]');
    $end = strpos($rstring, '</a>', $start);
    $name= trim(substr($rstring, $start, $end - $start));
    echo $name . '<br/>';
        //players
    $search = '<td class="c05 item_bgcolor_even">';
        $start = (strpos($rstring, $search) + strlen($search));
    $end = strpos($rstring, "</td>", $start);
    $players= trim(substr($rstring, $start, ($end - $start)));
    echo $players . '<br />';
    $map;
    $curPlayers;
    $maxPlayers;
    $ip;
}

It gets the server name correctly but when it comes to players, one line i get them and the other I get lor_odd”> 1230.

It’s going to be way easier with a DOM parser:

libxml_use_internal_errors(true);

$dom = new DOMDocument;
$dom->loadHTMLFile('http://www.gametracker.com/search/');
$xpath = new DOMXPath($dom);

// Get the rows from the search list
$rows = $xpath->query('//table[@class="table_lst table_lst_srs"]/tr');

for ($i=1; $i<$rows->length-1; $i++) {
    $row = $rows->item($i);

    // Get the columns for a row
    $cols = $row->getElementsByTagName('td');

    // Get the server name (3rd column)
    echo 'Name: '.trim($cols->item(2)->textContent).PHP_EOL;

    // Get the player count (5th column)
    echo 'Players: '.trim($cols->item(4)->textContent).PHP_EOL.PHP_EOL;
}

Outputs:
