这篇文章主要介绍了PHP使用Alexa API获取网站的Alexa排名例子,需要的朋友可以参考下
我们通会用Alexa的网站(或其它站长工具网站)来栓查我们的网站流量排名,这样就必须去那些网站。实际上,可以通过Alexa XML API 获取网站的Alexa相关的数据(XML格式的),再使用XML解析器来解析Alexa返回的XML,得到Alexa排名或其它的数据。
Alexa接口
Alexa的XML API接口是:?cli=10&url=%YOUR_URL%
如果想获取更多的数据可以用:?cli=10&dat=snbamz&url=%YOUR_URL%
用?cli=10&dat=snbamz&url=jb51.net返回的数据如下:
复制代码 代码如下:
其中POPULARITY元素中的TEXT属性的值7552101就是Alexa排名。
代码实现:
用PHP实现通过Alexa API 获取Alexa排名的代码为:
复制代码 代码如下:
function getAlexaRank ($Domain){
$line = "";
$data = "";
$URL = "http://data.alexa.com/data/?cli=10&dat=snba&url=". $Domain ;
$fp = fopen ($URL ,"r");
if ($fp ){
while (!feof ($fp )){
$line = fgets ($fp );
$data .= $line ;
}
$p= xml_parser_create ();
xml_parse_into_struct ($p , $data , $vals );
xml_parser_free ($p );
for ($i =0 ;$i
return $vals [$i ]["attributes"]["TEXT"];
}
}
}
}
?>
使用方法:
复制代码 代码如下:
echo getAlexaRank("jb51.net");
?>

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),
