[pmwiki-users] PHP warning in HandyTableContents

[Hans-Jürgen Godau]

PHP-Warning of using $[var} instead of {$var} appeared for me in
HandyTableOfContents: cookbook/handytoc.php on lines 69 and 71.
So I changed it from
return Keep("$script_set_args<div ${class}id='htoc'><h3>$title</h3></div>");
return Keep("$script_set_args<div ${class}id='htoc'></div>");
to
return Keep("$script_set_args<div {$class}id='htoc'><h3>$title</h3></div>");
return Keep("$script_set_args<div {$class}id='htoc'></div>");
and the warning disappeared.
