如何从网址获取价值？

If I have url like this: www.example.com/product/yellow-bed is it possible to retrieve product name from url? For example, if url would be like www.example.com?page=product&product_name=yellow_bed I would use:

$product = $_GET['page'];
$product_name = $_GET['product_name'];

But how to get it from www.example.com/product/yellow-bed ?

Get the URI by "$_SERVER["REQUEST_URI"]". Convert the string into an array with explode:

$uri = 'www.google.com/product/yellow-bed' //uri = $_SERVER["REQUEST_URI"]
$uriArray = explode('/', $uri);
$product = $urlArray[1];
$product_name = $urlArray[2];

0 = www.google.com, 1 = product, 2 = yellow-bed

PHP manual: array explode ( string $delimiter , string $string [, int $limit ] ).

Some php frameworks (like CodeIgniter) has already this function implemented. Never the less you can have a look here: http://erunways.com/simple-php-get-uri-or-segment-element/ , and that should solve your problem.

You could fetch the complete URI with $_SERVER['QUERY_STRING'] and then split it apart. Or you work with an .htaccess and internally rewrite the url.

Try $_SERVER[ 'PATH_INFO' ] or $_SERVER[ 'REQUEST_URI' ].

You should have a look at $_SERVER['REQUEST_URI']. This will be /product/yellow-bed in your example.

You can then use strrpos(), explode() orpreg_match()` (or other string manipulation functions) to extract what you want.

you can use the following function to retrive current url:

<?php
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;
}
?>

now you can take url and parse its elements using parse_url : http://php.net/manual/en/function.parse-url.php
