Old schooled but hope this works

$str = explode("\n", $str);

foreach($str as $val){   
    if(!empty($val)){        
       $result[] = $val; 
    }    
}

$final = implode("\n", $result); //if you want line break use "<br>"
echo $final;

if you want line break use '
' instead of "\n" when implode. when you use "\n" you can see the new line in viewsource – ASR Jun 10 '16 at 04:34
Or is this you want? `$final = implode("

", $result);` – ASR Jun 10 '16 at 04:37
