Bug description:Inconsistency in operators precedence example
Description:
------------
---
From manual page: http://www.php.net/language.operators.precedence
---
There's an inconsistency in Example #2 on the "Language Operators
Precedence" page.
The example states that the script "may print either 2 or 3", but
actually, it will *always* print "3", and for the second script, the
array will *always* be equal "[2 => 1]".
This might confuse people about the real role of precedence operators.
You can check on 3v4l here: https://3v4l.org/EUknn
Test script:
---------------
// First script
$a = 1;
echo $a + $a++;
echo "\n";
// Second script
$i = 1;
$array[$i] = $i++;
var_export($array);
