Are you sure that the output of:
<?php
$foo1="nonsense";
$foo2="foo1";
print "$$foo2";
?>
is: $foo2
Under PHP 4.0.6 (Win2k and Linux) the script generates $foo1 when I run it.

Perhaps one of the developers could comment? I don't know if the behavior needs to be
changed or just documented.
I would **guess** that we could extend the lexer to handle this by adding something
like:
<ST_DOUBLE_QUOTES,ST_BACKQUOTE,ST_HEREDOC>"$$" {
yy_push_state(ST_LOOKING_FOR_VARNAME);
return T_VARIABLE;
}
However, I have not tested it and really have no idea what I am doing! :)

<?php
$foo1="nonsense";
$foo2="foo1";
print "$$foo2";
?>
THIS programs output $foo2, (IS THIS OK??)
<?php
$foo1="nonsense";
$foo2="foo1";
print "{$$foo2}";
?>
this program outputs nonsense (THIS IS CORRECT)
