PHP gets all the variable names and values ​​passed in through GET_PHP Tutorial

The requirement of this blog is that I need to take out all the get parameters from an http request such as 127.0.0.1?a=123&b=456&c=789 and string them behind test.com, that is, the final ideal uri should be test.com ?a=123&b=456&c=789

There are two ways to achieve it. It is recommended to google before doing it. I just don’t have google and it leads to rework

$_SERVER["QUERY_STRING"]

Introduction

This is the simplest method, but most people may not be too familiar with this server variable. Please explain it

[html]

$_SERVER["QUERY_STRING"] : Query string

Code

[php]

$base = "test.com";

$str = $_SERVER["QUERY_STRING"];

$uri = $base.$str;

echo $uri;

Effect

$_GET array for loop to string together

Thoughts

When most people encounter this kind of demand, their first reaction should be to use a for loop to GET the array. Just put the string together yourself and write an implementation code to share

Code

[php]

$str = "test.com?";

$count = count($_GET);

$i = 0; www.2cto.com

foreach ($_GET as $key => $value) {

if ($i == $count - 1) {

$str .= $key . "=" . $value;

} else {

$str .= $key . "=" . $value . "&";

}

$i ++;

}

echo $str;
