Description

array headers_list ( void )

headers_list() will return a numerically indexed array of headers to be sent to the browser / client. To determine whether or not these headers have been sent yet, use headers_sent().

Example 1. Examples using headers_list()
<?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()); ?>
this will output :
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" }
