Not true. Array references inside double quotes behave differently. Inside
double quotes $a[b] is the same as {$a['b']} and constant lookup is not
done.

>From the doc:
// Works but note that this works differently outside string-quotes
echo "A banana is $fruits[banana].";
// Works
echo "A banana is {$fruits['banana']}.";
// Works but PHP looks for a constant named banana first
// as described below.
echo "A banana is {$fruits[banana]}.";
// Won't work, use braces. This results in a parse error.
echo "A banana is $fruits['banana'].";
