What is the best method to extract specific values from a multidimensional array in PHP?

When working with a multidimensional array in PHP, the best method to extract specific values is by using nested loops to iterate through the array and access the desired values based on their keys. By using nested loops, you can navigate through the array structure and extract the specific values that you need. 

// Example multidimensional array
$multiArray = array(
    "key1" => array(
        "subkey1" => "value1",
        "subkey2" => "value2"
    ),
    "key2" => array(
        "subkey1" => "value3",
        "subkey2" => "value4"
    )
);

// Extract specific value from the multidimensional array
foreach ($multiArray as $key => $value) {
    foreach ($value as $subkey => $subvalue) {
        if ($key == "key1" && $subkey == "subkey1") {
            echo $subvalue; // Output: value1
        }
    }
}
