PHP strpos问题
|
我有一个脚本，该脚本使用cURL从站点中获取页面，而我试图逐行将其切开，然后提取我需要的内容并删除该行。问题是，有时它会为我提供正确位置的项目，有时它不会根据行的不同而交替显示。
我试图使用以下页面之一：http://www.gametracker.com/search/
我使用的代码是：
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;
}

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; }辽躺
$doc = new DOMDocument(); $doc->loadHTML($contents); // $contents = the HTML that curl returns $xpath = new DOMXPath($doc); // You can now use as many XPath queries as you like; they look like this: $nodes = $xpath->query(\'\'); // you own query expression here foreach ($nodes as $node) { $v = $node->nodeValue; // now do something with $v }
