If the number begins with a zero, there seems to be no way to tell PHP this
is an integer, not an octal. The conversion happens as soon as the number is
stored in the variable, it appears, which is why everything done afterwards
makes no difference, because $id=11; seems to be stored as $id=>9 by
PHP.
011 and 9 are the exact same number, but represented in different bases!
Maybe this is the concept you're not grasping. When you say $id =
11, then you're telling PHP to assign the value of 9 to $id, plain
and simple.
Can we take a step back here and ask where you're getting "11" from?

This is expected, $id becomes 9 as soon as you assign it. the ltrim() function's dont see any 0. this will work however: $id = "011"; echo (int)$id; - or $id = "011"; echo ltrim($id, '0'); > No matter what I do, $id=11 is seen as "9".

Thats because 11 is an integer in octal notation.

ever tryed telling PHP to display the variable as an integer?

How do I make the first number (00011) display as 11? Why is it showing

First of all you have "naked" numbers. The first one, 11, looks like
a binary number (which actually should be 3). You are going to have to
trim the leading zero's from the number to have it display as 11.
