You use [ ] on arrays such as:
$someArray[0] = "0123456789";
$someArray[1] = "rock 'n roll";
echo $someArray[0] will output:
0123456789
echo $someArray[1] will output:
rock 'n roll
You use { } on strings such as:
$someString1 = "0123456789";
$someString2 = "rock 'n roll";
echo $someString1{5} will output:
5
echo $someString2{3} will output:
k
strings are zero based... with this method you can manipulate strings at the
character level if you want.
