php file_get_contents gets Baidu hot word code_PHP tutorial

This is a very simple program that uses PHP's file_get_contents function to collect Baidu data, and then parses the data through simplexml_load_String, so that the data is saved in an array, which we can use conveniently.

The code is as follows

 代码如下

复制代码

function getBaiduHotKeyWord()
{
    $templateRss = file_get_contents('http://top.baidu.com/rss_xml.php?p=top10');
    If (preg_match('/

(.*)/is', $templateRss, $_description)) {
        $templateRss = $_description [0];
        $templateRss = str_replace("&", "&", $templateRss);
    }
    $templateRss = "" . $templateRss;
    $xml = simplexml_load_String($templateRss);
    foreach ($xml->tbody->tr as $temp) {
        if (!empty ($temp->td->a)) {
            $keyArray [] = trim(($temp->td->a));
        }
    }
    return $keyArray;
}

Copy code

function getBaiduHotKeyWord()
{
$templateRss = file_get_contents('http://top.baidu.com/rss_xml.php?p=top10');
If (preg_match('/(.*)/is', $templateRss, $_description)) {
         $templateRss = $_description [0];
          $templateRss = str_replace("&", "&", $templateRss);
}
$templateRss = "" . $templateRss;
$xml = simplexml_load_String($templateRss);
foreach ($xml->tbody->tr as $temp) {
If (!empty ($temp->td->a)) {
                $keyArray [] = trim(($temp->td->a));
         }
}
Return $keyArray;
}
