    ▪PHP使用SOAP调用.net的WebService数据       这个与一般的PHP POST或GET传值再查库拿数据的思路有点不一样，需要用到SOAP模块，处理方法也很简单，就是有一些需要注意的事情。首先确认你的PHP.ini开启了.SOAP，就是 extension=php_soap.dll 这.........

    ▪php获取远程图片体积大小的实例       直接看代码吧，很好明白的 代码如下://用法 echo remote_filesize($url,$user='',$pw='');$url = "http://www.aa.com/librarys/images/random/rand_11.jpg";//这里要换成你的图片地址echo remote_filesize($url,$user='',$pw=''); functi.........

    ▪php过滤XSS攻击的函数       下面的函数可以用来过滤用户的输入，保证输入是XSS安全的。具体如何过滤，可以参看函数内部，也有注释。 代码如下:<?phpfunction RemoveXSS($val) {     // remove all non-printable characters. CR(0a) an.........

代码如下:

<?php
$client = new SoapClient('http://www.aa.net/SearchService.asmx?WSDL');//这个SOAP地址要换成你自己的
$client->soap_defencoding = 'utf-8'; 
$client->decode_utf8 = false;  
$client->xml_encoding = 'utf-8';
$param = array('param1'=>'01', 'param2'=>'02');
//$param["param1"]="01";
//$param["param2"]="02";
//$result = $client->__soapCall("GetArticle", array( $param ));
$result = $client->__Call("GetArticle", array( $param ));
if (is_soap_fault($result))
{
    trigger_error("SOAP Fault: (faultcode: {$result->faultcode}, faultstring: {$result->faultstring})", E_USER_ERROR);
}
else
{
    $data = $result->GetArticleResult; //这里返回的是类，必须使用->得到元素的值
    print_r($data);
}
?>

代码如下:

POST /SearchService.asmx HTTP/1.1
Host: 202.105.183.61
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://tempuri.org/GetTrafficViolationInfo"

  <soap:Body>
    <GetArticle xmlns="http://tempuri.org/">
      <param1>string</param1>
      <param2>string</param2>
    </GetArticle>
  </soap:Body>
</soap:Envelope>

代码如下:

//用法 echo remote_filesize($url,$user='',$pw='');
$url = "http://www.aa.com/librarys/images/random/rand_11.jpg";//这里要换成你的图片地址
echo remote_filesize($url,$user='',$pw='');

// start output buffering
    ob_start();
// initialize curl with given uri
    $ch = curl_init($uri); // make sure we get the header
    curl_setopt($ch, CURLOPT_HEADER, 1); // make it a http HEAD request
    curl_setopt($ch, CURLOPT_NOBODY, 1); // if auth is needed, do it here
    if (!empty($user) && !empty($pw))
    {
        $headers = array('Authorization: Basic ' . base64_encode($user.':'.$pw));
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    }
    $okay = curl_exec($ch);
    curl_close($ch); // get the output buffer
    $head = ob_get_contents(); // clean the output buffer and return to previous // buffer settings
    ob_end_clean();  // gets you the numeric value from the Content-Length // field in the http header
    $regex = '/Content-Length:\s([0-9].+?)\s/';
    $count = preg_match($regex, $head, $matches);  // if there was a Content-Length field, its value // will now be in $matches[1]
    if (isset($matches[1]))
    {
        $size = $matches[1];
    }
    else
    {
        $size = 'unknown';

 $last_kb = round($size/1024,3);
