Why is it discouraged to generate PHP files dynamically in PHP scripts?

Generating PHP files dynamically in PHP scripts is discouraged because it can lead to security vulnerabilities, make code harder to maintain, and can be less efficient than alternative methods like using databases or configuration files. Instead, consider using databases or configuration files to store dynamic data and retrieve it in your PHP scripts. 

// Example of retrieving dynamic data from a database in a PHP script
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

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

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

// Query to retrieve dynamic data from database
$sql = "SELECT * FROM myTable";
$result = $conn->query($sql);

// Loop through data and output it
if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        echo "Name: " . $row["name"]. " - Email: " . $row["email"]. "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();
