Are there any best practices for handling multiple user inputs in PHP to avoid the need for a status variable?

When handling multiple user inputs in PHP, it's common to use a status variable to keep track of the validation or processing status for each input. However, a more efficient approach is to use an associative array to store the status for each input field. This way, you can easily check the status of each input without cluttering your code with multiple status variables. 

// Using an associative array to store status for multiple user inputs
$input_status = [];

// Validate input fields
if(isset($_POST['username'])) {
    // Validate username
    if(/* Username validation condition */) {
        $input_status['username'] = 'valid';
    } else {
        $input_status['username'] = 'invalid';
    }
}

if(isset($_POST['email'])) {
    // Validate email
    if(/* Email validation condition */) {
        $input_status['email'] = 'valid';
    } else {
        $input_status['email'] = 'invalid';
    }
}

// Check status for each input field
if($input_status['username'] == 'valid') {
    // Process username
}

if($input_status['email'] == 'valid') {
    // Process email
}
