如何在本地主机上修剪我的家庭URL

Question

This is how I get my url on my localhost:

 $url = (!empty($_SERVER['HTTPS'])) ? "https://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'] : "http://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'];
    echo $url;

it returns : http://localhost/CodeSensei/menu because I am on the menu page.

How can I trim this? I only want " http://localhost/CodeSensei "

I know I can trim it like this

echo trim($url,"menu");

But the problem is, that "menu" is dynamic, it keep changing dependes on the page. Is there any way to trim my url so it will always and only print " http://localhost/CodeSensei " in any page?

This function may help you. It get a url and return the url without after the last / .

<?php
function getSubUrl($originUrl) {
    $url = parse_url($originUrl);
    $url['scheme'] .= '://';
    $url['path'] = dirname($url['path']);

    return implode($url);
}


echo getSubUrl('http://localhost/CodeSensei/menu/123') . PHP_EOL;
// http://localhost/CodeSensei/menu
echo getSubUrl('http://localhost/CodeSensei/menu') . PHP_EOL;
// http://localhost/CodeSensei
echo getSubUrl('http://localhost/CodeSensei') . PHP_EOL;
// http://localhost/
echo getSubUrl('http://localhost/') . PHP_EOL; 
// http://localhost/
echo getSubUrl('http://localhost') . PHP_EOL;
// http://localhost

There are many ways to achieve this. You can play around with different string manipulators like explode() etc.

Here is a solution using explode()

$variable =  "http://localhost/CodeSensei/menu";
$variable = (explode("/",$variable));
$url='';

for($i=2;$i<count($variable)-1;$i++)
{  
    $url .= "/".$variable[$i];
}

$final_url = "http:/".$url;

echo $final_url;

Your output

http://localhost/CodeSensei
