The get_object_vars() function is an inbuilt function in PHP that is used to get the properties of the given object. When an object is made, it has some properties. An associative array of properties of the mentioned object is returned by the function. But if there is no property of the object, then it returns NULL.
Syntax:
get_object_vars( $object )
Parameters: This function accepts a single parameter as mentioned above and described below:
$object: This parameter holds the object of an instance.
Return Value: This method returns an associative array object accessible non-static properties for the specified object in scope.
Below programs illustrate the get_object_vars() function in PHP:
Program 1:
PHP
<?php // Declare a class class gfg { // Properties of an object // of this class private $neveropen = 0.02; public $for = 1; public $Geeks = "php" ; private $GEEKS ; static $e ; public function example() { var_dump(get_object_vars( $this )); } } // Create an object of a class $example = new gfg; // Display properties of the // newly created object var_dump(get_object_vars( $example )); $example ->example(); ?> |
array(2) { ["for"]=> int(1) ["Geeks"]=> string(3) "php" } array(4) { ["neveropen"]=> float(0.02) ["for"]=> int(1) ["Geeks"]=> string(3) "php" ["GEEKS"]=> NULL }
Program 2:
PHP
<?php // Create a class class coordinate { // The properties of the // object of this class var $x ; var $y ; var $z ; var $labels ; function coordinate( $x , $y , $z ) { $this ->x = $x ; $this ->y = $y ; $this ->z = $z ; } function to_set( $labels ) { $this ->labels = $labels ; } } $point1 = new coordinate(0.1, 0.2, 0.3); print_r(get_object_vars( $point1 )); $point1 ->to_set( "point 1" ); print_r(get_object_vars( $point1 )); ?> |
Array ( [x] => 0.1 [y] => 0.2 [z] => 0.3 [labels] => ) Array ( [x] => 0.1 [y] => 0.2 [z] => 0.3 [labels] => point 1 )
