=== Perl/PHP ===
[[Perl]] supports hard references, which function similarly to those in other languages, and '''symbolic references''', which are just string values that contain the names of variables. When a value that is not a hard reference is dereferenced, Perl considers it to be a symbolic reference and gives the variable with the name given by the value.<ref>{{cite web|url=http://perldoc.perl.org/perlref.html#Symbolic-references |title=perlref |publisher=perldoc.perl.org |access-date=2013-08-19}}</ref> [[PHP]] has a similar feature in the form of its <code>$$var</code> syntax.<ref>{{cite web|url=http://www.php.net/manual/en/language.variables.variable.php |title=Variable variables - Manual |publisher=PHP |access-date=2013-08-19}}</ref>
