Bug description:Offset access should trigger error for integers and bools
Description:
------------
Invalid offset access triggers some kind of errors for strings (and of
course arrays):
$str = 'abc';
echo $str[TRUE]; // Notice: String offset cast occurred
echo $str[NULL]; // Notice: String offset cast occurred
echo $str[[]]; // Warning: Illegal offset type
But it triggers no error when variable is integer, float or bool, which
is inconsistent:
$int = 123;
echo $int[1]; // no error
echo $int[TRUE]; // no error
echo $int[[]]; // no error
Test script:
---------------
https://3v4l.org/JCXR1
<?php
$str = 'abc';
echo $str[TRUE]; // Notice: String offset cast occurred
echo $str[NULL]; // Notice: String offset cast occurred
echo $str[[]]; // Warning: Illegal offset type
$int = 123;
echo $int[1]; // no error
echo $int[TRUE]; // no error
echo $int[[]]; // no error
$bool = TRUE;
echo $bool[1]; // no error
echo $bool[TRUE]; // no error
echo $bool[[]]; // no error
Expected result:
----------------
trigger errors
