Help with big array

Question

I'm trying to access some words from a string, using an array, here's the array:

$array_lugares = array(
    array(
        "barra" => array(
            /*SENTIDO BARRA*/
            "Sao conrado" => array("-22.999743", "-43.270694"),
            "Elevado do Joa" => array("-22.999429", "-43.27317")
        ),
        "zona sul"=>array(
            /*SENTIDO ZONA SUL:*/
            "passarela da barra" => array("-23.008346", "-43.303708"),
            "barra grill" => array("-23,010576", "-43,302028"),
            "lagoa barra" => array("-22,997348", "-43,263200")
        ),
        "recreio" => array(
            /*SENTIDO RECREIO:*/
            "passarela da barra" => array("-23.008283", "-43.303634"),
            "rio mar" => array("22.999958", "-43.402648"),
            "ribalta" => array("-22,999753", "-43,409211")
        )
    )
);

when I do:

foreach ($array_lugares[0]['zona sul'] as $lugar) {
    echo $lugar;
    echo "</br>";
}

the output is:

Array
Array
Array

how can I make it so it shows:

barra
zona sul 
recreio

in the output, is it possible?

Answer 1

 foreach($array_lugares[0] as $k => $lugar){
   echo $k;
   echo "</br>";
 }

Answer 2

That is because you have a multidimensional array, you can loop through $lugar; also, and it will give you the correct output

Update:

foreach($array_lugares[0]['zona sul'] as $lugar){
   foreach ($lugar as $value) {
     // further inside the array

   }

 echo "</br>"; 

} 

but i think you should revisit the code you have and see if this is really the way you want to work with your data
