How can you ensure that multiple error messages are stored in the variable $message when multiple conditions are met?

When multiple conditions are met and you want to store multiple error messages in the variable $message, you can concatenate the error messages using the dot (.) operator in PHP. This way, each error message will be appended to the existing $message variable. 

$message = '';

if ($condition1) {
    $message .= 'Error message 1. ';
}

if ($condition2) {
    $message .= 'Error message 2. ';
}

if ($condition3) {
    $message .= 'Error message 3. ';
}

echo $message;
