How to create a copy of an object in PHP? Last Updated : 01 Dec, 2021 Comments Improve Suggest changes Like Article Like Report An object copy is created by using the clone keyword (which calls the object's __clone() method if possible). An object's __clone() method cannot be called directly. When an object is cloned, PHP will perform a shallow copy of all of the object's properties. Any properties that are references to other variables will remain references.Syntax: $copy_object_name = clone $object_to_be_copied Program 1: Program to create copy of an object. php <?php // Program to create copy of an object // Creating class class GFG { public $data1; public $data2; public $data3; } // Creating object $obj = new GFG(); // Creating clone or copy of object $copy = clone $obj; // Set values of $obj object $obj->data1 = "Geeks"; $obj->data2 = "for"; $obj->data3 = "Geeks"; // Set values of copied object $copy->data1 = "Computer "; $copy->data2 = "science "; $copy->data3 = "portal"; // Print values of $obj object echo "$obj->data1$obj->data2$obj->data3\n"; // Print values of $copy object echo "$copy->data1$copy->data2$copy->data3\n"; ?> Output: GeeksforGeeks Computer science portal Example 2: Below program distinguishes clone from assignment ( = ) operator. php <?php // Program to create copy of an object // Creating class class GFG { public $data1; public $data2; public $data3; } // Creating object $obj = new GFG(); // Creating clone or copy of object $copy = clone $obj; // Creating object without clone keyword $obj_ref = $obj; // Set values of $obj object $obj->data1 = "Geeks"; $obj->data2 = "for"; $obj->data3 = "Geeks"; // Set values of copied object $copy->data1 = "Python "; $copy->data2 = "for "; $copy->data3 = "Machine learning"; // Print values of $obj object echo "$obj->data1$obj->data2$obj->data3\n"; // Print values of $copy object echo "$copy->data1$copy->data2$copy->data3\n"; // Print values of without clone object echo "$obj_ref->data1$obj_ref->data2$obj_ref->data3\n"; ?> Output: GeeksforGeeks Python for Machine learning GeeksforGeeks Note: It is clear that cloned object have different values than original object but original and referenced object created by using '=' operator have same value.
