foreach($data as $key => $value){ 
    if($value["city"] != ""){ 
     if($count[$value["city"]] == ""){ $count[$value["city"]] = 1; } 
     else{ $count[$value["city"]]++; } 
    } 
} 

foreach($count as $key => $value){ 
    echo "There are ".$value." users from ".$key."<br>"; 
} 

echo "<br><br>"; 

foreach($data as $key => $value){ 
    foreach($value as $key => $value){ 
    if(($value != "")&&($key != "hobbies")&&($key != "skills")){ 
     echo $key." : ".$value."<br>"; 
    } 
    if(($key == "hobbies")||($key == "skills")){ 
     echo $key.":<br>"; 
     foreach($value as $kk => $vv){ 
      if($vv != ""){ 
       echo "-".$vv."<br>"; 
      } 
     } 
    } 
    } 
    echo "<hr>";
