How to translate placeholder?

Question

I don't know how to translate text that I use as placeholder for my comment form. I have a function in my function.php file where is defined how comment form should look like. Here is example of that code:

    $fields =  array(
        'author' => '<p class="comment-form-author">' .
                '<input id="author" name="author" placeholder="Name" type="text" required value="' . esc_attr( $commenter['comment_author'] ) . '" size="30"' . $aria_req . ' />',
        'email'  => '<p class="comment-form-email"> ' .
                '<input id="email" name="email" placeholder="E-mail" type="text" required value="' . esc_attr(  $commenter['comment_author_email'] ) . '" size="30"' . $aria_req . ' /></p>',
        'url'    => '<p class="comment-form-url">' .
                '<input id="url" name="url" placeholder="Website" type="text" value="' . esc_attr( $commenter['comment_author_url'] ) . '" size="30" /></p>',
     );

Can you help me here?

In your code, you are concatenating a string but you are (from a comment) using a function that echos information-- _e(). You can't do that. You are printing the content wherever that array is constructed, which is not what you want.

Use __() instead.
