NO SUCH THING AS AN INVALID STRING. his problem is understanding the
unexpected results. you already explained that to him, it just seems he's
still lost.

php doesn't parse strings whenever it feels like it. the only reason you
have to escape strings *you* create in php is because you have the ability
to put variables in the strings and use octal,hex, and other special
character notation in the string...some of which you cannot use the keyboard
to produce in any other way. but, that's only when YOU are creating them.
if your path is coming from a db, php doesn't care what data type a field
is. if you assign a db field's value to a variable, php just assigns it.
this is quite different than you saying literally that $var = "some
$stringVariable". and that is interpreted differently than $var = 'some
$stringVariable'. one is parsed, the other, literal.
