Previous Comments: ------------------------------------------------------------------------ [2001-07-20 14:14:23] zak@php.net Are you sure that the output of: <?php $foo1="nonsense"; $foo2="foo1"; print "$$foo2"; ?> is: $foo2 Under PHP 4.0.6 (Win2k and Linux) the script generates $foo1 when I run it. From looking at the parser, this does not seem to be an error - at most just an omission. Perhaps one of the developers could comment? I don't know if the behavior needs to be changed or just documented. I would **guess** that we could extend the lexer to handle this by adding something like: <ST_DOUBLE_QUOTES,ST_BACKQUOTE,ST_HEREDOC>"$$" { 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! :) ------------------------------------------------------------------------ [2001-07-20 08:15:32] dardo@uol.com.ar <?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) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=12278&edit=1
