PHP cUrl自动登录

Question

如果可以使用php curl自动登录脚本，我需要一些帮助。

我正在处理一个项目，其中一个问题是我需要登录：http://www.marketbook.co.uk并废弃一些信息，但只能登录。

如果您可以节省一些时间，请查看我的代码并告诉我出了什么问题：

<?php

// options
$USER             = 'userrrrrrrr';
$PASSWORD         = 'passsssssss';
$cookie_file_path = "cookies.txt";
$LOGINURL         = "http://www.marketbook.co.uk/Homepage/Default.aspx"; 
$agent            = "Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/45.0.2454.101 Safari/537.36";


// begin script
$ch = curl_init(); 

// extra headers
$headers[] = "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8";
$headers[] = "Connection: Keep-Alive";

// basic curl options for all requests

// set first URL
curl_setopt($ch, CURLOPT_URL, $LOGINURL);

// execute session to get cookies and required form inputs
$content = curl_exec($ch); 

// grab the hidden inputs from the form required to login

// set postfields using what we extracted from the form
$POSTFIELDS = http_build_query($fields); 

// change URL to login URL
curl_setopt($ch, CURLOPT_URL, $LOGINURL); 

// set post options
curl_setopt($ch, CURLOPT_POST, 1); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $POSTFIELDS); 

// perform login
$result = curl_exec($ch);  

print $result; 


function getFormFields($data)

    if (preg_match('/(<form action="op.*?<\/form>)/is', $data, $matches)) {
        $inputs = getInputs($matches[1]);

        return $inputs;
    } else {
        die('didnt find login form');
    }
}

function getInputs($form)

    $inputs = array();

    $elements = preg_match_all('/(<input[^>]+>)/is', $form, $matches);

            if (preg_match('/name=(?:["\'])?([^"\'\s]*)/i', $el, $name)) {
                $name  = $name[1];
                $value = '';

                if (preg_match('/value=(?:["\'])?([^"\'\s]*)/i', $el, $value)) {
                    $value = $value[1];
                }

                $inputs[$name] = $value;
            }
        }
    }

    return $inputs;
