Bug description:No documentation for accessing array elements with curly braces
Description:
------------
I have only seen documentation for using $var{n} syntax for accessing
single characters in strings. Apparently, it is completely interchangeable
with $var[n] for arrays as well. Is this intended?
Seeing as it is only noted that strings may be accessed using curly braces,
I would expect the variable to be typecast to string.
Test script:
---------------
<?php
$foo = array('123');
$bar = 'abc';
echo $foo . "\r\n"; // Outputs "Array", as expected
echo $bar . "\r\n"; // Outputs "abc", as expected
echo $foo[0] . "\r\n"; // Outputs "123", as expected
echo $bar[0] . "\r\n"; // Outputs "123", as expected
echo $foo{0} . "\r\n"; // Outputs "123", undocumented (?), expected
implicit cast to string, thus expected the output to be "A"
echo $bar{0} . "\r\n"; // Outputs "a", as expected
?>
Expected result:
----------------
Array
abc
123
a
A
a
Actual result:
--------------
Array
abc
123
a
123
a
