How to break vk url?

Question

PHP

I need to know how to break the VK link https://vk.com/wall-1234567_890 into post_id and owner_id variables.
I tried something myself, it doesn’t work, I tried it like parse_url , but even my hosting didn’t understand how this function works, it’s not like you, I don’t even have a brain. In general, I either don’t know how to work with this function, or I don’t know anything at all. Can you help?
Decision:

<?

preg_match('/wall(\d+)_(\d+)/', 'wall-1234567_890', $matches);
list(, $post_id, $owner_id) = $matches;

var_dump($post_id, $owner_id);

?>

Answer 1

There are a lot of options. Simplest:

php > preg_match('/wall-(\d+)_(\d+)/', 'https://vk.com/wall-1234567_890', $matches);
php > var_dump($matches);
array(3) {
  [0]=>
  string(16) "wall-1234567_890"
  [1]=>
  string(7) "1234567"
  [2]=>
  string(3) "890"
}

// EDIT
With all due respect, it's absurd to ask that in an addendum.)
// EDIT 2 for the little ones

<?php

preg_match('/wall-(\d+)_(\d+)/', 'wall-1234567_890', $matches);
list(, $post_id, $owner_id) = $matches;

var_dump($post_id, $owner_id);
