Question

Simply put,

I have a string with a prefix “msg” followed by some numbers that serve as the ID for a list item

e.g.

<li id="msg1"></li>..............<li id="msg1234567890"></li>

What is the most efficient way to grab just the numbers?

In VB, I’d do the following:

str = "msg1"
str = right(str,len(str)-3)

How would I do something similar (or more efficient) in PHP?

Answer 1

the same in php (using substr):

$str = "msg1";
$str = substr($str,3);
