#49068 [Bgs]: Using undefined assoc array index does not cause notice inside foreach
ID: 49068 User updated by: simon+php at thulbourn dot com Reported By: simon+php at thulbourn dot com Status: Bogus Bug Type: Scripting Engine problem Operating System: * PHP Version: 5.*, 6SVN (2009-07-26) New Comment: I believe that it should issue a warning rather than converting to an integer. It seems like a retarded action to convert the string to a 0, if I was to use a numeric index that doesn't exist, I'd receive a notice. Some consistency would be nice. Previous Comments: [2009-07-26 23:07:46] ras...@php.net That has nothing to do with a foreach. The same effect can be seen with: $a = 'foo'; echo $a['bar']; $a is a string which is essentially an array of characters with numerical indices. Given that, 'bar' is converted to an integer, so you end up with $a[0] which does exist, so no warning. ------------ [2009-07-26 22:09:07] simon+php at thulbourn dot com Description: An array with no associative keys doesn't throw a notice or error when one is used as an associative keyed array.

Granted, I could have provided a better sample case so:
$a = array('foo');
// echo a index that doesn't exist
echo $a['bar'];
PHP should produce a notice claiming an undefined index 'bar', instead
it outputs the first char of the 0 index, in this case 'f', it's
obviously converting the string to a 0 instead of producing the notice.

$a is a string which is essentially an array of characters with
numerical indices. Given that, 'bar' is converted to an integer, so you
end up with $a[0] which does exist, so no warning.

Sorry, the new test code was wrong, here's one that proves my point
$blah = "foo";echo $blah["frog"];
