本文实例讲述了php获取发送给用户的header信息的方法。分享给大家供大家参考。具体分析如下：

headers_list函数没有参数，并返回一个数组。返回的数组包含一个数字索引表，包含了要发送给客户端的header信息

<&#63;php
  header("Expires: Sat, 12 Dec 1989 05:30:00 GMT");
  echo "This is some output.<br />";
  echo "Headers sent are:<br /> <UL>";
  $headers = headers_list();
  foreach($headers as $header) {
    echo "<LI>$header</LI>";
  }
  echo "</UL>";
&#63;>
Copy after login

希望本文所述对大家的php程序设计有所帮助。
