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

> /*QUOTE
> stripcslashes('He\xallo') == 'He'."\n".'llo'
> stripcslashes('H\xaello') == 'H'.chr(0xAE).'llo'
> */

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...

fix'd

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'
