How can is_object() and foreach be used together to check for objects in an array in PHP?

To check for objects in an array in PHP, you can use a combination of is_object() and foreach loop. The is_object() function checks if a variable is an object, and then you can iterate through the array using a foreach loop to check each element. If an element is an object, you can perform the necessary actions.

$myArray = [1, "hello", new stdClass(), "world", new stdClass()];

foreach ($myArray as $element) {
    if (is_object($element)) {
        // Perform actions for objects
        echo "Found an object in the array!";
    }
}
