How can array_keys be utilized to simplify the process of generating column names dynamically for an SQL insert statement in PHP?

When generating column names dynamically for an SQL insert statement in PHP, you can utilize the `array_keys` function to extract the keys of an associative array, which can then be used as column names. This simplifies the process by automatically generating the column names based on the keys of the associative array.

$data = array(
    'name' => 'John Doe',
    'age' => 30,
    'email' => 'johndoe@example.com'
);

$columns = implode(", ", array_keys($data));
$values = ":" . implode(", :", array_keys($data));

$sql = "INSERT INTO table_name ($columns) VALUES ($values)";
