Question

I have a database of more than 70000 records and its primary key value started from 1 single digit.

So I want user have to type nm0000001 instead of 1 in url.And in code part I have to discard the rest of the value except 1.

But my problem is i want this type of things having 9 letters in the string and the pattern is like this

1    - nm0000001
9    - nm0000009
10   - nm0000010
2020 - nm0002020

And from the above pattern i want only the digits like 1,9,10,2020 in php.

Answer 1

Assuming the value is received in the URL as a querystring parameter, that is, passed via $_GET['id'] or some other name than id:

// Trim the "nm" off the front
$pk = substr($_GET['id'],2);
// And parse out an integer value.
$id = intval($pk);
