How can hosting providers like Strato impact the functionality and performance of PHP scripts?

Hosting providers like Strato can impact the functionality and performance of PHP scripts by limiting resources such as memory, CPU usage, and execution time. To optimize the performance of PHP scripts on such hosting providers, it is important to streamline the code, minimize database queries, and utilize caching techniques.

// Example of optimizing PHP script performance by minimizing database queries
$conn = new mysqli($servername, $username, $password, $dbname);

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

// Perform a single query to fetch data
$sql = "SELECT * FROM table_name WHERE condition";
$result = $conn->query($sql);

// Process the fetched data
if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        // Process each row of data
    }
} else {
    echo "0 results";
}

$conn->close();
