it fixes the issue The class system in Smalltalk is an interesting one to study. In Smalltalk, everything is an object and every object has a class. This doesn't imply that the hierarchy goes to infinity. If I remember correctly, it goes something like:
5 -> Integer -> Integer class -> Metaclass -> Metaclass class -> Metaclass -> ... (it loops)

Wordpress SQL Select Multiple Meta Values / Meta Keys / Custom Fields

I wish did fix the issue. I am trying to modify a wordpress / MySQL function to display a little more information. I'm currently running the following query that selects the post, joins the 'postmeta' and gets the info where the meta_key = _liked , The SQL will look very ugly.
code :
// Your Meta key names
    $metas = array(
        '_liked', '_another1'

    foreach ($metas as $i=>$meta_key) {
        $meta_fields[] = 'm' . $i . '.meta_value as ' . $meta_key;
        $meta_joins[] = ' left join ' . $wpdb->postmeta . ' as m' . $i . ' on m' . $i . '.post_id=' . $wpdb->posts . '.ID and m' . $i . '.meta_key="' . $meta_key . '"';
    $request = "SELECT ID, post_title, " .  join(',', $meta_fields) . " FROM $wpdb->posts ";
    $request .=  join(' ', $meta_joins);
    $request .= " WHERE post_status='publish' AND post_type='post'";
    $request .= " LIMIT $numberOf";

PHP meta generating code inside the <head> section of my website does not add new lines between each meta tag

Does that help Well, actually the cause is simply that you do not specify any linebreaks. You have to output linebreaks as well if you want them to be generated, just like with every other conent.
I usually use this syntax, since it does not make the code unreadable:
code :
if((is_home() && $currentpage == 1) || (is_single() && $title != 'Online' && $title != 'Cam') || (is_category() && $robots == 'y')){
        echo '<meta name="robots" content="index,follow"/>'."\n";   
    } else {
        echo '<meta name="robots" content="noindex,follow"/>'."\n";
    if(get_option('enable_wmt') == 'y'){
        echo '<meta name="google-site-verification" content="'.get_option('wmt').'"/>'."\n";
    if (is_home() && $currentpage == 1){
        echo '<link rel="alternate" type="application/rss+xml" title="RSS 2.0" href="'.$site_current.'/feed/"/>'."\n";
