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

http://php.net/manual/en/language.types.array.php
> Strings containing valid integers will be cast to the integer type. E.g. the key
> "8" will actually be stored under 8.

Having [1] and ["1"] be distinct would create chaos.

Description:
------------
[harry@rh:/downloads]$ php test.php
Fatal error: Uncaught TypeError: Argument 1 passed to test() must be of the type string, integer given, called in /mnt/data/downloads/test.php on line 11 and defined in /mnt/data/downloads/test.php:13
Stack trace:
#0 /mnt/data/downloads/test.php(11): test(1, 'c')
#1 {main}
  thrown in /mnt/data/downloads/test.php on line 13
____________________________________

why in the world is the array-key silently cased to an integer - if that would have been the intention the code would be 1=>'c' instead '1'=>'c'

besides that this breaks strict mode that conversion are useless cpy-cycles

Test script:
---------------
[harry@rh:/downloads]$ cat test.php
<?php declare(strict_types=1);
$arr =
[
 'a' => 'a',
 'b' => 'b',
 '1' => 'c',
 '2' => 'd'
];
foreach($arr as $key=>$value)
{
 test($key, $value);
}
function test(string $a, string $b)
{

}
