এজন্য clone ব্যবহার করুন এবং প্রপার্টি নামকে null সেট করুন।
উদাহরণ
PHP কোডটি নিচে দেওয়া হলো—
<!DOCTYPE html> <html> <body> <?php $firstObject = (object)[ "Name" => "John", "Age" => 20 ]; $secondObject = clone $firstObject; var_dump($firstObject); echo "<br>"; var_dump($secondObject); foreach ($secondObject as $keyName => $keyValue) { $secondObject->$keyName = null; } echo "<br>"; var_dump($secondObject); $firstObject = [ "Name" => "John", "Age" => 20 ]; echo "<br>"; $arrayObject = array_fill_keys(array_keys($firstObject), null); $secondObject = (object)$arrayObject; var_dump($secondObject); ?> </body> </html>আউটপুট
এটি নিচের আউটপুট দেবে—
object(stdClass)#1 (2) { ["Name"]=> string(4) "John" ["Age"]=> int(20) } object(stdClass)#2 (2) { ["Name"]=> string(4) "John" ["Age"]=> int(20) } object(stdClass)#2 (2) { ["Name"]=> NULL ["Age"]=> NULL } object(stdClass)#1 (2) { ["Name"]=> NULL ["Age"]=> NULL }
