How can you extract specific values from a JSON object and store them in a new array using PHP?

To extract specific values from a JSON object and store them in a new array using PHP, you can first decode the JSON object using `json_decode()`, access the specific values using their keys, and then store those values in a new array. This can be achieved by looping through the decoded JSON object and selecting only the desired values to be stored in the new array. 

$jsonObject = '{"key1": "value1", "key2": "value2", "key3": "value3"}';
$decodedObject = json_decode($jsonObject, true);

$newArray = array();
$keysToExtract = array("key1", "key3");

foreach($keysToExtract as $key) {
    if(isset($decodedObject[$key])) {
        $newArray[$key] = $decodedObject[$key];
    }
}

print_r($newArray);
