How to prioritize strpos to find me the most accurate result

Question

I have an array:

$array_of_routes = ['users/', 'articles/more', 'users/get', 'homepage/'];

And, For example I have a string:

$route = "users/get/1"; 

So I tried to find it by using strpos but because 'users/' comes a head of 'users/get' in $array_of_routes I get the 'users/' in return and not the 'users/get', This is makes sense because that is what I asked the code to do.

But is there a way to priorotize or make the result more accurate when trying to find a substring in a string?

Note: when removing 'users/' from the array I get the 'users/get'

This is my code:

foreach($array_of_routes as $uri){
  if(strpos($current_uri, $uri) !== false)
    return $uri;

}

Thanks you for your help!

You need to break apart the $route and match it with the highest specificity available in $array_of_routes

<?php
$array_of_routes = ['users', 'articles/more/', 'users/get', 'homepage'];
$route = "users/get/1/fgd/d/fg/";

// No reason to have trailing nor leading slashes or spaces; they are just noise
$array_of_routes = array_map(function($v){return trim(trim($v, '/'));}, $array_of_routes );
$route = trim(trim( $route, '/' ));

// Get the requested route pieces
$route_pieces = explode('/', $route);

// Make sure we loop enough times to account for all of the pieces
for($i = 0; $i<count($route_pieces); ++$i)
{
    // With each loop, build the route with one piece less and check if it exists in $array_of_routes
    if(in_array(implode('/', array_slice($route_pieces, 0, (count($route_pieces)-$i))), $array_of_routes))
    {
        echo 'Most specific route: '.implode('/', array_slice($route_pieces, 0, (count($route_pieces)-$i)));
        echo 'Arguments: '.implode('/', array_slice($route_pieces, (count($route_pieces)-$i)));
        break;
    }
}

Output for $route = "users/get/1/fgd/d/fg/";:

Most specific route: users/get
Arguments: 1/fgd/d/fg
