No, of course not -- I repeat:

Please note the {}, which you *MUST* include to get the array index processed
properly. If you write:
"$_POST['insert']"
PHP will try to interpret this as the variable called $_POST followed by the string
"['insert']", which is clearly not what you want. including the {} forces it to use
the value of $_POST['insert'], which *is* what you want.
Incidentally, I've occasionally had problems including a variable name containing an
underscore in a double-quoted string (e.g. "$num_recs records retrieved"), where PHP
tries to insert the value of $num followed by the string "_recs", so I always {} those
as well, just to be on the safe side ("{$num_recs} ..." or "${num_recs} ..." both work.
Cheers!
