PHP Bug Type: Arrays related
Bug description: array keys that are strings but numeric behave incorrectly
Description:
------------
This is really bug #23935, but that's marked 'Closed' and I am still
seeing the problem in the current PHP5 code. It's beyond array_flip(),
too, strictly. I first saw this in $_POST with a field named "myfield[1]"
- this comes through as $_POST["myfield"]["1"]. Same with array_combine()
using array("1") as the key array.
Reproduce code:
---------------
submit a form with hidden field named 'myfield[1]':
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="POST">
<input type="hidden" name="myfield[1]" value="1" >
<input type="submit">
</form>
<?php
function testit($a)
{
static $tick = 1;
echo "<li>test ", $tick++, ":\n";
var_dump($a, array_key_exists(key($a), $a), empty($a[1]),
empty($a['1']));
}
testit(array("1"=>"1"));
testit(array_flip(array(1=>"1")));
testit(array_combine(array('1'),array('1')));
if (!empty($_POST['myfield'])) { testit($_POST['myfield']); }
?>
Expected result:
----------------
Output for test 2 on PHP 4.3.3RC1 (cli) (built: Jun 20 2003 23:09:34)
(DEBUG):
array(1) {
[1]=>

}

Actual result:
--------------
Output for test 2 on PHP 5.0.0b2-dev (cli) (built: Jul 14 2003 14:14:54)
(DEBUG):
array(1) {
["1"]=>

}
