PHP Echo a multidimensional array

I have a multidimensional array that when i use print_r looks like this:

Array ( 

[car] => Array (   
           [72] => Camry 
           [62] => Lexus 
           [55] => honda 
           [44] => toyota 
                )

[Job] => Array (   
           [70] => Bookstore
           [73] => Cafe 
               ) 

[City] => Array (  
           [68] => Wisconsin
           [63] => Chicago 
           [47] => New York City 
           [46] => Los Angeles 
                ) 
 )

This is a Parent/Child Multidimensional array. There can be any number of parents, and any number of children.

How do I echo out a multidimensional array so that it looks like this

Car
    Camry 
    Lexus 
    honda 
    toyota

Job
    Bookstore
    Cafe

City
    Wisconsin
    Chicago
    New York City
    Los Angeles

My attempt at printing a multidimensional array out:

function RecursiveWrite($array) {
                      foreach ($array as $vals) {
                          echo $vals['parent'] . "\n";
                          RecursiveWrite($vals['child']);
                      }
                  }     
RecursiveWrite($categories); // $categories is the name of the array

This doesn't print out any output when I run the code. Any suggestions?

the below code shows as you want:

 <?php
$arrayToPrint = Array (
        'car' => Array (   
        '72' => 'Camry', 
        '62' => 'Lexus', 
        '55' => 'honda', 
        '44' => 'toyota'
        ),
        'Job' => Array (   
        '70' => 'Bookstore',
        '73' => 'Cafe' 
        ) ,
        'City' => Array (  
        '68' => 'Wisconsin',
        '63' => 'Chicago' ,
        '47' => 'New York City', 
        '46' => 'Los Angeles'
        ) 
    ) ;
    echo "output in print_r( ):<pre>";
    print_r($arrayToPrint);
    echo "</pre>";
    echo "output in echo:<br/>";
    foreach($arrayToPrint as $arrayKey=> $arrayValue1) {
        echo '<pre>';
        echo $arrayKey;
            foreach($arrayValue1 as $leafNodeValue) {
                echo '<pre>    '.$leafNodeValue.'</pre>';
            }
        echo '</pre>';
    }
    ?>

Create a recursive function:

Semi-psuedo:

function dumpArr (arr){
  foreach element in arr {
    if element is array/object{
      dumpArr(element)
    }else{
      echo element
    }
  }
}

then, you can use CSS to adjust the padding, margin, etc

Considering that the tab and return symbols depends on whatever you want an HTML or FILE output here it is the code:

$tab = "\t"; // tab
$return = "\r"; // return

foreach ($array as $key => $a) {
    echo $key.$return;
    foreach ($a as $value) {
        echo $tab.$value.$return;
    }
}
