How can PHP be integrated into a mobile app for database access?

To integrate PHP into a mobile app for database access, you can create a web service using PHP that interacts with the database and returns data in a format like JSON or XML. The mobile app can then make HTTP requests to the PHP web service to retrieve or update data in the database. 

<?php
// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

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

// Retrieve data from the database
$sql = "SELECT * FROM table";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data in JSON format
    $rows = array();
    while($row = $result->fetch_assoc()) {
        $rows[] = $row;
    }
    echo json_encode($rows);
} else {
    echo "0 results";
}

$conn->close();
?>
