说明
array
headers_list ( void )
headers_list() 将返回一个数字索引的数组,包含有向浏览器/客户端发送的标头。要判断标头是否已被发送,使用
headers_sent()。
例子 1. headers_list() 例子
<?php
/* setcookie() will add a response header on its own */ setcookie('foo', 'bar');
/* Define a custom response header This will be ignored by most clients */ header("X-Sample-Test: foo");
/* Specify plain text content in our response */ header('Content-type: text/plain');
/* What headers are going to be sent? */ var_dump(headers_list());
?>
|
上例的输出类似于: array(4) {
[0]=>
string(29) "X-Powered-By: PHP/5.0.0"
[1]=>
string(19) "Set-Cookie: foo=bar"
[2]=>
string(18) "X-Sample-Test: foo"
[3]=>
string(24) "Content-type: text/plain"
} |
