PHP亂入，post，mysql串連，抓取網頁_PHP教程

post

 '0',    'pwd' => '1',);/*$pageContents = HttpClient::quickPost('http://xxxxxxxxx',$params);echo $pageContents;*/$client = new HttpClient('xxxxxx');$client->setDebug(true);$client->post('/action',$params);echo $client->getContent();// foreach (json_decode($client->getContent(), true) as $item)//echo $item['name'].'
';?> '0',    'pwd' => '1',);/*$pageContents = HttpClient::quickPost('http://xxxxxxxxx',$params);echo $pageContents;*/$client = new HttpClient('xxxxxx');$client->setDebug(true);$client->post('/action',$params);echo $client->getContent();// foreach (json_decode($client->getContent(), true) as $item)//echo $item['name'].'
';?>

mysql串連：

";     echo "asdfasdfadsf";    $mysql_server_name="xxxxx"; //資料庫伺服器名稱    $mysql_username="root"; // 串連資料庫使用者名稱    $mysql_password="root"; // 串連資料庫密碼    $mysql_database="bookshop"; // 資料庫的名字        // 串連到資料庫    $conn=mysql_connect($mysql_server_name, $mysql_username,                        $mysql_password);                             // 從表中提取資訊的sql語句    $strsql="SELECT * FROM `book`";    // 執行sql查詢    $result=mysql_db_query($mysql_database, $strsql, $conn);    // 擷取查詢結果    $row=mysql_fetch_row($result);             echo '';    echo ''.      mysql_field_name($result, $i);      echo "";    }    echo "';        echo $row[$i];        echo '';      }      echo "
 
  ';    // 顯示欄位名稱    echo "
  
    "; for ($i=0; $i
   "; // 定位到第一條記錄 mysql_data_seek($result, 0); // 迴圈取出記錄 while ($row=mysql_fetch_row($result)) { echo "
   
    "; for ($i=0; $i
   "; } echo "
  ";    echo "";    // 釋放資源    mysql_free_result($result);    // 關閉串連    mysql_close($conn);  ?>
