Hi Macca,
No - the parser will recognise the $ and what follows it as a variable
name, and will stop with the next character that can't be part of a
variable name (IIRC only letters, digits, and _ are allowed).
thus
$var = "fred";
$array[2] = "bill";
echo ">$var<"; // = '>fred<'
echo ">$array[2]<"; // error ($array is not convertible to a string.)
echo ">{$array[2]}<" // = '>bill<'
Regards
Ian
