如何使用PHP从URL中删除最后一个元素？

Question

I have $url = "example.com/en/category/node/extra/"; and I need to remove extra from $url, how could I do that?

Answer 1

Explode the $_SERVER['SCRIPT_URL'] into an array, remove empty elements, and then remove the last array element. Then, implode it all back together with initial and trailing slashes.

$urlArray = explode('/',$_SERVER['SCRIPT_URL']);
$urlArray = array_filter($urlArray); 

// remove last element
array_pop($urlArray);

$urlString = '/'.implode('/',$urlArray).'/';

Don't store array_pop() as a variable, unless you need the last array element.
