What is the is_object method in PHP?

The is_object method can be used to check if the variable is an object or not.

Syntax

is_object(mixed $value): bool

The is_object method returns true if the passed value is an object. Otherwise, it returns false.

Code

<?php 
  class MyClass {
    
  }
  $test = new myClass();
  printIsObject($test);
  $test = new stdClass();
  printIsObject($test);
  $test = null;
  printIsObject($test);
  $test = 0;
  printIsObject($test);
  function printIsObject($test){
    echo "The Value is: ";
    var_dump($test);
    echo "Is Object: ";
    var_dump(is_object($test));
    
    echo "---------\n\n";
  }
?>

Explanation

In the code above:

  • We create an empty class with the name MyClass and create an object for it. We pass the created object to the is_object method, which returns true.

  • Similarly, we create an object for stdClass and call is_object with the created object as an argument.

  • For the values null and 0(int), the is_object method returns false because they are not objects.
