What best practices should be followed when working with stored procedures in PHP and MySQL?

When working with stored procedures in PHP and MySQL, it is important to properly handle input parameters to prevent SQL injection attacks. One best practice is to use prepared statements with bound parameters to securely pass user input to the stored procedure. Additionally, always validate and sanitize user input before passing it to the stored procedure to ensure data integrity. 

// Example of using prepared statements with bound parameters to call a stored procedure in MySQL

// Establish a connection to the database
$mysqli = new mysqli("localhost", "username", "password", "database");

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

// Prepare the stored procedure call with placeholders for input parameters
$stmt = $mysqli->prepare("CALL stored_procedure_name(?, ?)");

// Bind parameters to the placeholders
$stmt->bind_param("ss", $param1, $param2);

// Set the input parameters
$param1 = "input_value_1";
$param2 = "input_value_2";

// Execute the stored procedure
$stmt->execute();

// Close the statement and connection
$stmt->close();
$mysqli->close();
