What are the potential pitfalls of manually counting and assigning variables in PHP functions, especially when dealing with a large number of parameters?

Manually counting and assigning variables in PHP functions can be error-prone, especially when dealing with a large number of parameters. To avoid mistakes and make the code more maintainable, it's better to use an array or an associative array to pass parameters to the function. This way, you can access the values by their keys instead of relying on the order of parameters. 

function processParameters(array $params) {
    $param1 = $params['param1'] ?? null;
    $param2 = $params['param2'] ?? null;
    $param3 = $params['param3'] ?? null;
    
    // Process the parameters
}

// Usage
$params = [
    'param1' => 'value1',
    'param2' => 'value2',
    'param3' => 'value3'
];

processParameters($params);
