stripcslashes does not simply skip the C-style escape sequences \a, \b, \f, \n, \r, \t and \v, but converts them to their actual meaning.

So
<?php
stripcslashes
('\n') == "\n"; //true;

$str = "we are escaping \r\n"; //we are escaping

?>

Correct. But not what (I think) you were trying to show.

Not so correct.

Does 9==90? No, because that added zero *after* the number means something.
It's when you add a zero *before* the number does it not affect the value.

I'd like to assume that was a typo, but with the Internet as it is, who knows...

you might want to do a double stripslashes to completely remove 3 consecutive slashes

$stripped = 'this is a string with three\\\ slashes';
$stripped = stripslahses($stripped);
would output:
'this is a string with three\ slashes'

$stripped = 'this is a string with three\\\ slashes';
$stripped = stripslahses(stripslashes($stripped));
would output:
'this is a string with three slashes'
