In PHP, what are the common practices for handling associative arrays and transferring their data to new arrays?

When handling associative arrays in PHP, common practices include using foreach loops to iterate over the array and extract the key-value pairs, or using array functions like array_map or array_filter to manipulate the data. To transfer data from one associative array to another, you can simply assign the values directly or use functions like array_merge to combine arrays. 

// Example of transferring data from one associative array to another
$originalArray = array("name" => "John", "age" => 30, "city" => "New York");

$newArray = array();
foreach ($originalArray as $key => $value) {
    $newArray[$key] = $value;
}

print_r($newArray);
