Question

php curl中是否有任何命令可以打印响应查询字符串参数

以下是我的PHP代码

      <?php
      session_start();

      $ch = curl_init();
      curl_setopt($ch, CURLOPT_URL,"http://192.168.1.220/cgi-bin/handle_login.tcl");
     curl_setopt($ch, CURLOPT_POST, TRUE);
     curl_setopt($ch, CURLOPT_POSTFIELDS,
        "user=admin&pw=admin&submit=Login&sid=' '");        
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: x-www-form-urlencoded'));

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); 
     $response = curl_exec($ch);
     echo "$response";
     curl_close ($ch);
  ?>

查询字符串参数

    sid=3514275041172666092 //need to print these value

Answer 1

由于输出是字符串格式，输出每次都保持不变..需要找到字符串中所需字符的位置并提取所需的值..

以下是代码

           $response= curl_exec($ch);//executes the curl
           echo strpos("$response","variable_to_find")."<br/>";//know the position
           $sid = substr($response,position,length);
