最佳答案

<?php
// Replace XXXXXX_XXXX with the name of the header you need in UPPERCASE 用你需要的请求头的名字的大写来替换XXXXXX_XXXX
$headerStringValue = $_SERVER['HTTP_XXXXXX_XXXX'];
或者：你将PHP作为Apache的模块来运行或者从PHP 5.4开始，那么你可以使用FastCGI(简单的方法):
apache_request_headers()[[http://www.php.net/apache_request_headers]]
<?php
$headers = apache_request_headers();

foreach ($headers as $header => $value) {
    echo "$header: $value 
\n";
}

<?php
function getRequestHeaders() {
    $headers = array();
    foreach($_SERVER as $key => $value) {
        if (substr($key, 0, 5) <> 'HTTP_') {
            continue;
        }
        $header = str_replace(' ', '-', ucwords(str_replace('_', ' ', strtolower(substr($key, 5)))));
        $headers[$header] = $value;
    }
    return $headers;
}

$headers = getRequestHeaders();

foreach ($headers as $header => $value) {
    echo "$header: $value 
\n";
}
