What are the differences in handling database queries between PHP and other programming languages like Android?

When handling database queries in PHP, the most common method is to use the MySQLi or PDO extension to connect to the database, prepare and execute queries, and fetch results. On the other hand, in Android, database queries are typically handled using SQLite databases which are stored locally on the device. The syntax and methods for executing queries in PHP and Android differ due to the different database systems being used. 

// Example PHP code snippet for handling database queries using MySQLi extension

// Connect to the database
$connection = new mysqli('localhost', 'username', 'password', 'database_name');

// Check connection
if ($connection->connect_error) {
    die("Connection failed: " . $connection->connect_error);
}

// Prepare and execute a query
$query = "SELECT * FROM table_name";
$result = $connection->query($query);

// Fetch results
if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        echo "Column1: " . $row["column1"] . " - Column2: " . $row["column2"];
    }
} else {
    echo "0 results";
}

// Close connection
$connection->close();
