HTTP
소개
HTTP 확장은 주요 PHP 어플리케이션에 편리하고 강력한 기능을 제공하는 것이 목적입니다.
HTTP의 URL, 날짜, 리다이렉트, 헤더, 메세지를 쉽게 다룰 수 있게 합니다. 즉, 간단하게 임의의 데이터 전송에 캐시 및 재송신 기능을 부가할 수 있고, 클라이언트가 선호하는 언어와 문자셋에 대한 협상을 할 숟도 있습니다.
CURL 지원을 사용한다면, 강력한 요청 기능을 제공합니다. PHP 5 이상에서는 병렬 요청을 할 수 있습니다.
매뉴얼에 있는 추가적인 API 레퍼런스와 설치 및 설정을 하는 방법, 예약된 전역 상수를 다음 섹션에서 확인할 수 있습니다:
클래스
이 확장은 다음의 클래스들을 정의합니다. 이 확장을 PHP에 내장했거나, 실행시에 동적으로 읽어들일 경우에만 사용할 수 있습니다.
HttpResponse 클래스는 PHP v5.1 이상이 필요합니다. 다른 클래스는 PHP v5.0부터 사용할 수 있습니다.
Note: 몇몇 메쏘드는 PHP v5.0에서 사용할 수 없는 점에 주의하십시오.
함수
내장 함수
이 페이지에 있었던 HTTP 관련 내장함수는 네트워크 분류에서 찾아볼 수 있습니다.
다음 함수는 HTTP 모듈이 없어도 작동합니다: header(), headers_list(), headers_sent(), setcookie() 그리고 setrawcookie().

Actually, if you want to redirect a user why let HTML or JavaScript do it? Simply do this:
header("Location: http://www.example.com/");

Regarding what the guy before said. We've experienced problems where certain firewalls have encrypted the HTTP_REFERER meaning that it doesnt always contain the place you've come from.
Better to track where the user has come from either in a form post or in the url.

in reference to toashwinisidhu's and breaker's note, a more effective way would be to use meta-tag redirect, for example.
<?php
$url = "http://somesite.com/index.php"; // target of the redirect
$delay = "3"; // 3 second delay
echo '<meta http-equiv="refresh" content="'.$delay.';url='.$url.'">';
?>
The meta goes in the head of the HTML.
This method does not require javascript and is supported by most browsers and is rarely, if ever, filterd out.

The method given below may not sometimes work.
The following method has always worked with me:
just put the following 3 lines in your PHP code
?>
<body onload=setTimeout("location.href='$url'",$sec)>
<?PHP
-------?>
$sec is the time in second after which the browser would automatically go to the url. Set it to 0 if you do not want to give any time.
You can use this function on the events of various html/form objects (eg.-onclick for button).eg.
<input type=button value="Go to Php.net" onclick=setTimeout("location.href='php.net'",0)>
Use this to one step back
<input type="button" value="Back" onclick=history.go(-1)>

$HTTP_RAW_POST_DATA --
You'll usually access variables from forms sent via POST method by just accessing the associated PHP global variable.
However, if your POST data is not URI encoded (i.e., custom application that's not form-based) PHP won't parse the data into nice variables for you. You will need to use $HTTP_RAW_POST_DATA to access the raw data directly. (This should return a copy of the data given to the PHP process on STDIN; note that you wan't be able to open STDIN and read it yourself because PHP already did so itself.)
