How can dynamic array values be retrieved based on a key list in PHP?

To retrieve dynamic array values based on a key list in PHP, you can use a loop to iterate through the key list and access the corresponding values from the array using the keys. This can be achieved by checking if the key exists in the array and then retrieving the value associated with that key. 

<?php
// Sample dynamic array
$array = [
    'key1' => 'value1',
    'key2' => 'value2',
    'key3' => 'value3'
];

// Key list to retrieve values
$keyList = ['key1', 'key3'];

// Retrieve values based on key list
$result = [];
foreach ($keyList as $key) {
    if (array_key_exists($key, $array)) {
        $result[$key] = $array[$key];
    }
}

print_r($result);
?>
