note 32220 added to language.variables

I might mention that stlawson's comment is directly contradicted in Chapter 15: http://www.php.net/manual/en/language.references.php. References "are not like C pointers, they are symbol table aliases." And regarding "$a =& $b" it says "that's not $a is pointing to $b or vice versa, that's $a and $b pointing to the same place." Also, daevid's comment is contradicted in Chapter 15: http://www.php.net/manual/en/language.references.pass.php. (Actually, Daevid's syntax is still legal, but they're phasing it out.) ---- Manual Page -- http://www.php.net/manual/en/language.variables.php Edit Note -- http://master.php.net/manage/user-notes.php?action=edit+32220 Delete Note -- http://master.php.net/manage/user-notes.php?action=delete+32220&report=yes Reject Note -- http://master.php.net/manage/user-notes.php?action=reject+32220&report=yes
