How is the following evaluated:

Ignoring the 'assignment inside condition' arguments, is the return
value of somefunc() assigned to $data, and then $data's value is
evaluated (to true or false), or is the actual assignment tested (does
the assignment fail, etc)?
I believe that it determines if the return value of somefunc() is
non-false. It will have the added benefit then that you can use the
return value afterwards if it was, for example, not true, but a string
or something instead.
I do this all the time... an example is the following:
<?php
if( ($user = get_current_user()) )
{
// Yay, we have a user... do something.
echo $user->name();
}
else
{
// Handle no current user.
echo 'Anonymous';
}
?>
Cheers,
Rob.
