PHP gets all variable names and values passed in Get mode

PHP gets all the variable names and values passed in by the Get method

Objective

The requirement of this blog is that I need an HTTP request such as 127.0.0.1?a=123&b=456&c=789 to take all the get parameters out to the back of the test.com, that is, the final ideal URI should be test.com?a= 123&b=456&c=789

Two methods can be implemented, recommended to do before Google, I just don't have Google cause rework

$_server["Query_string"]

Brief introduction

This is the simplest approach, but most people may not be too familiar with this server variable, explaining

$_server["Query_string"]: query string

Code

$base = "test.com"; $str = $_server["Query_string"]; $uri = $base. $str; Echo $uri;

Effect

$_get array for loop string

Ideas

Most people meet this demand the first reaction should be a for loop get array, self-puzzle, write a implementation code share

Code

$str = "test.com?"; $count = count ($_get), $i = 0;foreach ($_get as $key + = $value) {    if ($i = = $count-1) {        $str. = $key. "=" . $value;    } else {        $str. = $key. "=" . $value. "&";    }    $i + +;} Echo $str;

Effect

Comparison

Although the effect is the same, but the get parameters for a long time, the efficiency of the For loop is certainly low, so use PHP to write code as little as possible to build their own wheels, so I prefer C, so can be more brain, alas, PHP is a fool's language, but it is indeed convenient!
