Getting the full URL of the current page (PHP)
提问by eozzy
I'm working on this page: http://localhost/projectname/custom.php
我正在这个页面上工作： http://localhost/projectname/custom.php
Both <?php echo $_SERVER['REQUEST_URI']; ?>and <?php echo $PHP_SELF; ?>don't give full location. What should I use to grab the full url location?
双方<?php echo $_SERVER['REQUEST_URI']; ?>并<?php echo $PHP_SELF; ?>没有充分的位置。我应该用什么来获取完整的 url 位置？

function selfURL()
{
$s = empty($_SERVER["HTTPS"]) ? '' : ($_SERVER["HTTPS"] == "on") ? "s" : "";
$protocol = strleft(strtolower($_SERVER["SERVER_PROTOCOL"]), "/").$s;
$port = ($_SERVER["SERVER_PORT"] == "80") ? "" : (":".$_SERVER["SERVER_PORT"]);
return $protocol."://".$_SERVER['SERVER_NAME'].$port.$_SERVER['REQUEST_URI'];
}
function strleft($s1, $s2) { return substr($s1, 0, strpos($s1, $s2)); }

There isn't a native method as far as I know, but you could use this:
据我所知，没有本地方法，但您可以使用它：
function curPageURL() {
$pageURL = 'http';
if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";}
$pageURL .= "://";
if ($_SERVER["SERVER_PORT"] != "80") {
$pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
} else {
$pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
}
return $pageURL;
}

If you are trying to add variables back onto the end of an URL that you are passing through a link tracking script, for example, you could try this:
例如，如果您尝试将变量添加回通过链接跟踪脚本传递的 URL 的末尾，您可以尝试以下操作：
$URI = array();
foreach($_GET as $key=>$val)
{
if ($key!="link"&&$key!="id"&&$key!="type") $URI[] = "$key=".urlencode($val);
}
if (sizeof($URI)>0) $link.="&".join("&",$URI);
In this case, "link", "id" and "type" were the variables I needed for the tracking, but the URL I wanted to track had a variable on the end of it that got stripped off by my script as if it was part of the query being sent to it; I needed the add it back to the link URL before passing it to header("Location:".$link).
在这种情况下，“link”、“id”和“type”是我进行跟踪所需的变量，但我想跟踪的 URL 末尾有一个变量，该变量被我的脚本剥离，好像它是发送给它的查询的一部分；在将它传递给 header("Location:".$link) 之前，我需要将它添加回链接 URL。
If this is what you are trying to achieve this works great and is shorter than above example.
如果这是您要实现的目标，那么效果很好，并且比上面的示例更短。

I found this code very helpful
我发现这段代码非常有帮助
$protocol = strpos(strtolower($_SERVER['SERVER_PROTOCOL']),'https') ===
FALSE ? 'http' : 'https'; // Get protocol HTTP/HTTPS
$host = $_SERVER['HTTP_HOST']; // Get www.domain.com
$script = $_SERVER['SCRIPT_NAME']; // Get folder/file.php
$params = $_SERVER['QUERY_STRING'];// Get Parameters occupation=odesk&name=ashik
$currentUrl = $protocol . '://' . $host . $script . '?' . $params; // Adding all
echo $currentUrl;

check this one... a bit long and dirty but works good...
检查这个......有点长而且脏，但效果很好......
function absolutizeUrl ( $u, $p )
{
$url = parse_url( $u );
$page = parse_url( $p );
if ( strpos( $u , '/' ) === 0 )
{
//already absolute
} else {
$basePath = '';
if (
isset( $page[ 'path' ] )
&& strpos( ltrim( $page[ 'path' ], '/' ), '/' )
)
{
$baseTokens = explode( '/', $page[ 'path' ] );
array_pop( $baseTokens ); // strip basename
$baseTokens[] = $u;
$u = join( '/', $baseTokens );
}
}
if ( ! isset( $url[ 'host' ]))
{
$u = 'http://'.$page[ 'host' ].'/'.ltrim( $u, '/' );
}
return $u;
}
