Get last Final Path of URL in php

  • 772

I am currently working on an MVC project in php and I need to get the path of the URL that I am entering in the following way:

Possible Entries (Examples)

  • .stackoverflow.com/questions/ask
  • .stackoverflow.com/questions/1
  • .stackoverflow.com/questions/

Desired results:

  • ask
  • 1
  • questions

For the specific purposes I have, I only work with numbers, but later I will have to work with any type of path. To solve my problem quickly use this function.

$vID=substr(str_replace("/", "", $_SERVER['REQUEST_URI']), -1);

This way I remove the "/" and get the last character. The problem is that this is only good for detecting single digit numbers. I removed the "/" so I would know that when I got an "e" it was because I was entering the template/ route.

I finally need to be able to find a way to get the last word after the last "/" and failing that, if there is nothing, it will return the last word before it.

Thank you so much guys!

    You could do the following:

    • Separate the string by each /usingexplode
    • Remove empty elements from the obtained array using array_filter.
    • Take only the last element of the array witharray_pop

    Example:

    $valor = @array_pop(array_filter(explode('/', '.stackoverflow.com/questions/')));
echo $valor;

  2. How about you try splitting the parts of the string like so:

    $url_ptr = explode("/", $_SERVER['REQUEST_URI']);

    And you use a conditional for the last element of the chain:

    if (end($url_ptr)==''){
    $vID = $url_ptr[count($url_ptr)-2];
} else {
    $vID = end($url_ptr);
}

    So, in cases where you have "stackoverflow.com/questions/", take not the last element of the explode (which is a ""), but the penultimate element, which is "questions". The end function takes the last element of the array.
