How can a Class-Map be effectively implemented in PHP to streamline object instantiation based on database keywords?
To streamline object instantiation based on database keywords in PHP, a Class-Map can be effectively implemented. This involves creating a mapping between database keywords and corresponding class names, allowing for dynamic object creation based on the data retrieved from the database.
// Define the Class-Map with database keywords and corresponding class names
$classMap = [
'user' => 'User',
'product' => 'Product',
'order' => 'Order'
];
// Retrieve the database keyword
$keyword = 'user';
// Instantiate the object based on the Class-Map
if(array_key_exists($keyword, $classMap)) {
$className = $classMap[$keyword];
$object = new $className();
// Use the object as needed
} else {
// Handle invalid database keyword
echo "Invalid database keyword";
}
