php中Curl函数常用的两个例子,登陆/soap

<?php
/** 
 * 模拟登陆
 * $url 请求地址
 * $post 需要POST的数据
 * $cookie 登陆时取的的COOKIE
 * $cookiejar cookie要存到的位置 例如/tmp/test.cookie
 * $referer 上页地址
 *
 *
 */
function vcurl($url, $post = &#39;&#39;, $cookie = &#39;&#39;, $cookiejar = &#39;&#39;, $referer = &#39;&#39;) {
    $tmpInfo = &#39;&#39;;
    //用来存放cookie的文件
    //初始化curl
    $curl = curl_init();
    //设定目标网址
    curl_setopt($curl, CURLOPT_URL, $url);
    //使用目前所用的浏览器代理
    curl_setopt($curl, CURLOPT_USERAGENT, $_SERVER[&#39;HTTP_USER_AGENT&#39;]);
    //curl_setopt($curl, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)");
    //如果有Ref参数，则设置Referer头，否则自动设置Referer头
    if ($referer) {
        curl_setopt($curl, CURLOPT_REFERER, $referer);
    } else {
        curl_setopt($curl, CURLOPT_AUTOREFERER, 1);
    }
    //如果有post数据参数，则方法为POST，并且设置数据，否则为GET
    if ($post) {
        //发送一个常规的POST请求，默认类型为：application/x-www-form-urlencoded，www.phprm.com表单提交
        curl_setopt($curl, CURLOPT_POST, 1);
        curl_setopt($curl, CURLOPT_POSTFIELDS, $post);
    }
    //如果有cookie参数，则设置
    if ($cookie) {
        curl_setopt($curl, CURLOPT_COOKIE, $cookie);
    }
    //如果有cookie文件参数，则设置存取Cookie文件名
    if ($cookiejar) {
        curl_setopt($curl, CURLOPT_COOKIEJAR, $cookiejar);
        curl_setopt($curl, CURLOPT_COOKIEFILE, $cookiejar);
    }
    //如果是302转移，则返回转移后的网址及内容
    curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
    //设置执行的最大秒数
    curl_setopt($curl, CURLOPT_TIMEOUT, 100);
    //返回内容中是否包含头信息
    curl_setopt($curl, CURLOPT_HEADER, 0);
    //把返回的结果存在文件或者变量中，而不是直接显示在浏览器
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    //执行函数后的返回结果
    $tmpInfo = curl_exec($curl);
    //如果出错，显示错误信息
    if (curl_errno($curl)) {
        $tmpInfo = &#39;<pre class="brush:php;toolbar:false"><b>错误:</b><br />&#39; . curl_error($curl);
    }
    //关闭curl对象
    curl_close($curl);
    //返回结果
    return $tmpInfo;
