First of all,

$var = "\\wusais\Intranets\Intranets\fpdb\pdf\weinig\00505882.pdf";

isn't really valid. The backslash character is the escape character.
In this case all but the last one have a non-escapable character after
them, so PHP just puts out the slash. However, if you had something like:

$var = "\\wusais\nbad\tworse";

The \n would be taken as a newline character and \t as a tab character.
And in the case of your last backslash, the \00505882 is taken as a
character with numberic value '005' (in octal), followed by 05882.

To get good output, you need to start with good input. Then something like:

Where is your string coming from? Are you actually defining it like
that? If so, it's invalid.
