Ein Zitat von Claude Sonnet 4.5:
Frage: "how is the strict equality check with two arrays? is it compared on values?"
Antwort: (gekuerzt)
...
// ❌ Numeric string keys vs int keys
$a = [0 => 'a', 1 => 'b'];
$b = ['0' => 'a', '1' => 'b'];
var_dump($a === $b); // false (int keys vs string keys)

Das ist alles in einer Antwort btw
...
// 3. Numeric string keys are converted to int!
$a = ['0' => 'a', '1' => 'b'];
$b = [0 => 'a', 1 => 'b'];
var_dump($a === $b); // true (PHP converts '0' -> 0 for keys)
