如何从php中的url中获取id并将其用作数字？

Question

I have a url that will look as follows.

post/:id

I am exploding the $_SERVER['REQUEST_URI'];

and I need to make the $uri[2] is numerical so I can do things like

$next = $uri[2]++;

I have tried is_numeric but of course the request_uri is a string (broken into an array of strings).

Can I type cast in php to integer?

Answer 1

$int = (int) $uri[2];

You just have to convert from string to integer.
