PHP Version: 4.1.1
New Comment:
Ooops. Getting confused about my posts (arrays versus strings).
OK, I've found the very brief comments on "String access by character"
-- that is, using {} to reference characters within strings --
documented near the end of
http://www.php.net/manual/en/language.types.string.php in the PHP
Manual.
As described this gets the caller a single charecter. A nice
enhancement would be to let the syntax also support ranges, by
accomodating an optional second argument, length. Examples:
$string = "abcde";
echo $string{1,3}; // To get "bcd" -- offset 1, length 3
But then you'd have to think about how to handle negative values, blah,
blah, blah.
I know, I know... You're going to bogus this because it's not likely
to ever get implemented. Never mind.
You might think about listing the {} operators (and the [], ->, and &
operators, too) in the operators section of the manual, however, to
make it easier for people to find out about them in the future.

Thank you. I know about substr() -- which is rather cumbersome
compared with the notation I suggested -- but I don't know what you
mean by {}.
I cannot find this notation explainined in the PHP Manual (at least not
in the pages about array functions, about the array type, nor in the
pages about operators).
Where is {} usage described?

Already supported by {} and substr.

The now very old North Star BASIC had a wonderful feature that I'd love
to see in PHP, which was the ability to access strings using
subscripts, rather like subscripting into an array, except even better
since it allowed ranges to be subscripted just as easily as single
characters in the strings.
Examples:
$string = "My String";
echo $string[5]; // returns "r"
echo $string[0,]; // returns "My String"
echo $string[3,5]; // returns "Str"
echo $string[,3]; // returns "My S"
