Bug description:isset/empty doesn't throw a TypeError on invalid string offset
Description:
------------
An invalid array offset will trigger a TypeError when used in
isset/empty.
The same should be done for string offsets.
Test script:
---------------
<?php
$s = 'Hello';
$o = new stdClass();
$a = [];
try {
var_dump(isset($s[$o]));
} catch (\Throwable $e) {
echo $e->getMessage(), "\n";
}
try {
var_dump(empty($s[$o]));
} catch (\Throwable $e) {
echo $e->getMessage(), "\n";
}
try {
var_dump(isset($s[$a]));
} catch (\Throwable $e) {
echo $e->getMessage(), "\n";
}
try {
var_dump(empty($s[$a]));
} catch (\Throwable $e) {
echo $e->getMessage(), "\n";
}
try {
var_dump(isset($s[[]]));
} catch (\Throwable $e) {
echo $e->getMessage(), "\n";
}
try {
var_dump(empty($s[[]]));
} catch (\Throwable $e) {
echo $e->getMessage(), "\n";
}
?>
