Check if an object has changed

Question

Is there a more native way (e.x. a built-in function) with less userland code to check if an objects property values have changed instead of using one of those methods:

Answer 1

We can implement it without observer.

For pure php, we can use $attributes & $original to check what has been modified check this explanation if needed.

$modifiedValues = [];
foreach($obj->attributes as $column=>$value) {
    if(!array_key_exists($column, $obj->original) || $obj->original[$column] != $value) {
        $modifiedValues[$column] = $value;
    }
}
// then check $modifiedValues if it contains values

For Laravel user, we can use the isDirty() method. Its usage:

$user = App\User::first();
$user->isDirty();          //false
$user->name = "Peter";
$user->isDirty();          //true
