Php 如何从curl post响应中获取[redirect_url]的值？

我使用下面的代码制作curl post。运行代码后，我看到一个数组输出，其中包含大量信息，包括重定向值。

（print\r（curl\u getinfo（$curl\u connection））；

如何引用该重定向值（

）并将其放在另一个变量中以供以后使用

<?php

//create array of data to be posted
$post_data['firstName'] = 'Name';
$post_data['action'] = 'Register';

//traverse array and prepare data for posting (key1=value1)
foreach ( $post_data as $key => $value) {
    $post_items[] = $key . '=' . $value;
}

//create the final string to be posted using implode()
$post_string = implode ('&', $post_items);

//create cURL connection
$curl_connection =
  curl_init('http://www.somesite.com/target_url.php');

//set options
curl_setopt($curl_connection, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($curl_connection, CURLOPT_USERAGENT,
  "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)");
curl_setopt($curl_connection, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl_connection, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl_connection, CURLOPT_FOLLOWLOCATION, 1);

//set data to be posted
curl_setopt($curl_connection, CURLOPT_POSTFIELDS, $post_string);

//perform our request
$result = curl_exec($curl_connection);

//show information regarding the request
print_r(curl_getinfo($curl_connection));
echo curl_errno($curl_connection) . '-' .
                curl_error($curl_connection);

//close the connection
curl_close($curl_connection);

?>
