What is the difference between using MySQL functions and ODBC functions in PHP for database operations?

When performing database operations in PHP, the main difference between using MySQL functions and ODBC functions lies in the database driver being used. MySQL functions are specific to MySQL databases, while ODBC functions provide a more generic way to interact with different types of databases through the Open Database Connectivity (ODBC) standard. If you need to work with multiple databases, using ODBC functions can provide more flexibility and portability in your code. 

// Using MySQL functions
$connection = mysqli_connect("localhost", "username", "password", "database");
$query = "SELECT * FROM table";
$result = mysqli_query($connection, $query);
while ($row = mysqli_fetch_assoc($result)) {
    // Process data
}
mysqli_close($connection);

// Using ODBC functions
$connection = odbc_connect("DSN", "username", "password");
$query = "SELECT * FROM table";
$result = odbc_exec($connection, $query);
while ($row = odbc_fetch_array($result)) {
    // Process data
}
odbc_close($connection);
