How can stored procedures or variables be utilized in PHP to streamline the process of connecting and executing multiple SQL queries?

Using stored procedures or variables in PHP can streamline the process of connecting and executing multiple SQL queries by reducing the amount of repetitive code needed for each query. By defining stored procedures or variables for commonly used queries, you can simply call these procedures or variables instead of writing out the entire query each time. 

// Example of using stored procedures in PHP to streamline SQL queries

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

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

// Define a stored procedure for retrieving user information
$sql = "CREATE PROCEDURE GetUser(IN userId INT)
        BEGIN
            SELECT * FROM users WHERE id = userId;
        END";

$conn->query($sql);

// Call the stored procedure to retrieve user information
$userId = 1;
$result = $conn->query("CALL GetUser($userId)");

// Process the result
if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        echo "User ID: " . $row["id"] . " - Name: " . $row["name"];
    }
} else {
    echo "No results found";
}

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