Unsupported string offset operations false-positive on array assignment

[fredricj]

The following (simplified) code triggers "Unsupported string offset operations: Provokes a PHP Fatal error (cannot use string offset as an array)":

$row = [1,2,3];
$plates = [];
foreach ($row as $t) {
    $header = "t";
    $plates[$header][] = $t; // Gives "Cannot use string offset as an array"
}

Thank you for reporting @fredricj. For some reason, I can not reproduce. Would you please check this code fragment in your environment?

function local_scope_only() {
    $row = [1,2,3];
    $plates = [];
    foreach ($row as $t) {
        $header = "t";
        $plates[$header][] = $t; // Gives "Cannot use string offset as an array"
    }
}

Wrapping it in a function does not trigger the message but removing the function scope from your code fragment emits the message again

Got it: I'll make adjustments. The inspection will skip global context and stick to functions and methods only.
