Array And Object Syntax, Not The Same Error¶

<?php

function foo() {
    yield 1;
    yield 2;
    yield 3;

    return ' 4';
}

function goo($a, $b, $c) {
    print "$a $b $c";
}
print PHP_EOL;

goo(...foo());

goo(...($g = foo()));
echo $g->getReturn();

?>

When accessing an array as an object, PHP raises a Warning and continues with NULL.

When accessing an object as an array, without ArrayAccess, PHP raises a Fatal Error and stops.

It is critical to check the syntax used to access an object.
