The following code:

$test['foo'] = "abc";
$test['foo']['bar'] = "123";

echo $test['foo'];    // Output "1bc"

The output is "1bc".  IMO, "abc" would be the only semantically correct output, although "Array" is also acceptable, which means value "abc" is replaced by array( 'bar' => "123").  The actual output "1bc" is definietly not correct.  This happens on all versions of PHP.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

it is the correct behaviour 
since test['foo'] is a string, using an array '[]' on a string returns the character:

eg.
echo $test['foo'][1]; //will equal 'b'

since ['bar'] evalates to 0 (zero)
it will replace character 'a' with the first character of "123"..

it would be nice to emit warnings on string[] format as string{n} is the advised method of using string position retreival/setting..

two at the same time :)

Wow, this is a surising side effect when string position retreival operator is the same as array operator.  Is there any way/plan to force [] as array operator and {} as string position opeartor?
