How can call_user_func_array() impact parameter passing in mysqli_stmt_bind_param()?

When using call_user_func_array() with mysqli_stmt_bind_param(), the issue arises because mysqli_stmt_bind_param() expects its parameters to be passed by reference, while call_user_func_array() passes parameters by value. To solve this issue, you can use the splat operator (...) to unpack the array of parameters and pass them by reference to mysqli_stmt_bind_param(). 

// Assuming $stmt is a mysqli_stmt object and $params is an array of parameters
$types = ''; 
$bindParams = [];
foreach ($params as $param) {
    $types .= 's'; // Assuming all parameters are strings, adjust accordingly
    $bindParams[] = &$param;
}

// Prepend types to the bindParams array
array_unshift($bindParams, $types);

// Call mysqli_stmt_bind_param() using call_user_func_array() with parameters passed by reference
call_user_func_array([$stmt, 'bind_param'], $bindParams);
