mysql连接:

<?php
    echo "This is a test</br>"; 
    echo "asdfasdfadsf";
    $mysql_server_name="xxxxx"; //数据库服务器名称
    $mysql_username="root"; // 连接数据库用户名
    $mysql_password="root"; // 连接数据库密码
    $mysql_database="bookshop"; // 数据库的名字
    
    // 连接到数据库
    $conn=mysql_connect($mysql_server_name, $mysql_username,
                        $mysql_password);
                        
     // 从表中提取信息的sql语句
    $strsql="SELECT * FROM `book`";
    // 执行sql查询
    $result=mysql_db_query($mysql_database, $strsql, $conn);
    // 获取查询结果
    $row=mysql_fetch_row($result);
    
     
    echo '<font face="verdana">';
    echo '<table border="1" cellpadding="1" cellspacing="2">';

    // 显示字段名称
    echo "</b><tr></b>";
    for ($i=0; $i<mysql_num_fields($result); $i++)
    {
      echo '<td bgcolor="#000F00"><b>'.
      mysql_field_name($result, $i);
      echo "</b></td></b>";
    }
    echo "</tr></b>";
    // 定位到第一条记录
    mysql_data_seek($result, 0);
    // 循环取出记录
    while ($row=mysql_fetch_row($result))
    {
      echo "<tr></b>";
      for ($i=0; $i<mysql_num_fields($result); $i++ )
      {
        echo '<td bgcolor="#00FF00">';
        echo $row[$i];
        echo '</td>';
      }
      echo "</tr></b>";
    }
   
    echo "</table></b>";
    echo "</font>";
    // 释放资源
    mysql_free_result($result);
    // 关闭连接
    mysql_close($conn);  
?>

抓取网页:

<?php 
header("content-type:text/html; charset=gbk");
$url='http://ipanda3.taobao.com/'; 
$lines_string=file_get_contents($url); 
echo $lines_string; 

抓取网页某个元素,使用simple_html_dom:



www.bkjia.comtruehttp://www.bkjia.com/PHPjc/735875.htmlTechArticlepost '0', 'pwd' => '1',);/*$pageContents = HttpClient::quickPost('http://xxxxxxxxx',$params);echo $pageContents;*/$client = new HttpClient('xxxxxx');$client->setDebug(true);$client...
