Homephp教程php手册用SQL语句读取XML和HTML文档

xml|语句

今天从phpclasses.org上发现的一个超牛的PHP类,这个类最特别的是可以用SELECT语句来从XML和HTML文档中读取特定的数据。例如下面是一个例子:

    /*
    ** htmlSQL - Example 1
    **
    ** 一个查询的简单例子  
 */
    //包含类文件
    include_once("../snoopy.class.php");
    include_once("../htmlsql.class.php");
    //创建对象
    $wsql = new htmlsql();
   
    // 连接上URL
    if (!$wsql->connect('url', '/')){
        print 'Error while connecting: ' . $wsql->error;
        exit;
    }
   
    /* 执行查询
        SELECT * FROM a 读取phpchina.cn首页的HTML中的所有的标记
    */
    if (!$wsql->query('SELECT * FROM a ')){
        print "Query error: " . $wsql->error;
        exit;
    }

    // 输出结果:
    foreach($wsql->fetch_array() as $row){
        print_r($row);
        /*
        $row 是像下面的一个数组:
        Array (
            [href] => /index.html
            [tagname] => a
            [text] => 首页
        )
        */ 
    }
?>

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
