Sorry if I was less than totally clear; I was referring to this part
of the page:
--------------------------------
Characters within strings may be accessed by specifying the
zero-based offset of the desired character after the string in curly
braces.
Note: For backwards compatibility, you can still use the
array-braces. However, this syntax is deprecated as of PHP 4.
Example 6-3. Some string examples
<SNIP>
/* Get the first character of a string */
$str = 'This is a test.'
$first = $str{0};
--------------------------------
...and that was the first I'd noticed that myself; I assume that the
{} syntax is only being used to refer to arrays as strings, to avoid
confusion with an array of strings -
$str = array('string 1', 'thing 2');
echo $str[0]; # produces 'string 1'
- and a scalar string variable being treated as an array of
characters. So I'm guessing (too lazy to test right at the moment)
that you would get
$str = array(array('bork','fubar'), 'snafu');
echo $str[0][1]; # produces 'fubar'
echo $str[1][1]; # produces null
echo $str[1]{1}; # produces 'n'
Again, that's just what I'm assuming from the docs. A quick test
would clear it up, but it doesn't affect me right now, and I'm
feeling lazy ;)
Hope that clears up my statement...
