PHP - parse current URL
提问by sol
I need to parse the current url so that, in either of these cases:
我需要解析当前 url，以便在以下任一情况下：
http://mydomain.com/abc/
http://www.mydomain.com/abc/
I can get the return value of "abc" (or whatever text is in that position). How can I do that?
我可以获得“abc”的返回值（或该位置的任何文本）。我怎样才能做到这一点？

You can use parse_url();
您可以使用parse_url();
$url = 'http://www.mydomain.com/abc/';
print_r(parse_url($url));
echo parse_url($url, PHP_URL_PATH);
which would give you
这会给你
Array
(
[scheme] => http
[host] => www.mydomain.com
[path] => /abc/
)
/abc/
Update:to get current page url and then parse it:
更新：获取当前页面 url，然后解析它：
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 $pageURL;
}
print_r(parse_url(curPageURL()));
echo parse_url($url, PHP_URL_PATH);

Take a look at the parse_url()function. It'll break you URL into its component parts. The part you're concerned with is the path, so you can pass PHP_URL_PATHas the second argument. If you only want the first section of the path, you can then use explode()to break it up using /as a delimiter.
看一下parse_url()功能。它会将您的 URL 分解为其组成部分。您关心的部分是路径，因此您可以将其PHP_URL_PATH作为第二个参数传递。如果您只需要路径的第一部分，则可以将explode()其/用作分隔符来分解它。
$url = "http://www.mydomain.com/abc/";
$path = parse_url($url, PHP_URL_PATH);
$pathComponents = explode("/", trim($path, "/")); // trim to prevent
// empty array elements
echo $pathComponents[0]; // prints 'abc'

To retrieve the current URL, you can use something like $url = "http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
要检索当前 URL，您可以使用类似 $url = "http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
If you want to match exactlywhat is between the first and the second / of the path, try using directly $_SERVER['REQUEST_URI']:
如果要完全匹配路径的第一个和第二个 / 之间的内容，请尝试直接使用$_SERVER['REQUEST_URI']：
<?php
function match_uri($str)
{
preg_match('|^/([^/]+)|', $str, $matches);
if (!isset($matches[1]))
return false;
return $matches[1];
}
echo match_uri($_SERVER['REQUEST_URI']);
Just for fun, a version with strpos()+ substr()instead of preg_match()which should be a few microseconds faster:
只是为了好玩，一个带有strpos()+substr()而不是preg_match()它的版本应该快几微秒：
function match_uri($str)
{
if ($str{0} != '/')
return false;
$second_slash_pos = strpos($str, '/', 1);
if ($second_slash_pos !== false)
return substr($str, 1, $second_slash_pos-1);
else
return substr($str, 1);
}

<?function urlSegment($i = NULL) {
static $uri;
if ( NULL === $uri )
{
$uri = parse_url( $_SERVER['REQUEST_URI'], PHP_URL_PATH );
$uri = explode( '/', $uri );
$uri = array_filter( $uri );
$uri = array_values( $uri );
}
if ( NULL === $i )
{
return '/' . implode( '/', $uri );
}
$i = ( int ) $i - 1;
$uri = str_replace('%20', ' ', $uri);
return isset( $uri[$i] ) ? $uri[$i] : NULL;} ?>
