What are some potential pitfalls when converting an array to an object in PHP?

One potential pitfall when converting an array to an object in PHP is that associative arrays can have keys that are not valid property names in PHP objects, such as keys starting with numbers or containing special characters. To solve this issue, you can use typecasting to convert the array to an object, ensuring that all keys are valid property names.

// Convert an array to an object, ensuring valid property names
$array = ['1key' => 'value1', 'key2' => 'value2'];
$object = (object) $array;

var_dump($object);
