PHP发送请求头和接收打印请求头

//发送地址
$url = ‘http://127.0.0.1/2.php‘;
//请求头内容
$headers = array(
    ‘Authorization: ‘.$basic,
    ‘suibianzhi: ‘.$basic,
);
//使用curl发送
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$result = curl_exec($ch);
curl_close($ch);
echo $result;

$headers = array();
foreach ($_SERVER as $key => $value) {
    if (‘HTTP_‘ == substr($key, 0, 5)) {
        $headers[str_replace(‘_‘, ‘-‘, substr($key, 5))] = $value;
    }
}    
echo ‘<pre>‘;
print_r($headers);
