The PHP manual is currently supposed to document the behavior for
all PHP versions as of PHP 5.0.0.

This change is documented in the migration guide: https://php.net/manual/en/migration71.incompatible.php#migration71.incompatible.array-order

Moreover, this change applies to all array functions and not just array_push() and I don't
think that this old behavior should be documented (due to the fact everything pre PHP 7.1 is EOL).

Description:
------------
---
From manual page: https://php.net/function.array-push
---

Despite the note in the documentation "Note: array_push() will raise a warning if the first
argument is not an array. This differs from the $var[] behaviour where a new array is
created.",  this is not correct for PHP >= 7.1 where a Fatal Error is thrown when the
variable is a empty string.

See https://3v4l.org/SPBA6

Test script:
---------------
$var = '';
$var[] = 'make me an array';

Expected result:
----------------
According to the docs a new array should be created. 

Actual result:
--------------
Fatal error: Uncaught Error: [] operator not supported for strings in /in/SPBA6:5 Stack trace: #0
{main} thrown in /in/SPBA6 on line 5
Process exited with code 255.
