PHP利用curl获取验证码,发送cookie二次抓取

<?php
$CookieFile = tempnam("./tmep", "beast");
if (isset($_GET["img"])) {
    $url = &#39;http://www.phprm.com/&#39;; //验证码code
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_COOKIEJAR, $CookieFile); //把返回来的cookie信息保存在文件中
    curl_exec($ch);
    curl_close($ch);
    exit();
}
if (isset($_POST[&#39;d&#39;])) {
    $b = $_POST[d]; //验证码
    $p = "waybillNo=1721269381&inputcode=" . $b;
    $ch = curl_init();
    // 2. 设置选项，包括URL
    curl_setopt($ch, CURLOPT_URL, "http://www.phprm.com");
    curl_setopt($ch, CURLOPT_COOKIEJAR, $CookieFile);
    curl_setopt($ch, CURLOPT_COOKIEFILE, $CookieFile); //同时发送Cookie
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $p); //提交查询信息
    $s = curl_exec($ch);
    curl_close($ch);
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, "http://www.phprm.com");
