PHP Inherit the properties of non-class object?
For this, use clone along with set the property name to null.
Example
The PHP code is as follows
<!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>
Output
This will produce the following output
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 }
