This would have been easier if you'd posted the php code to create the
array, as opposed to the output of print_r. I did this:
<?php
$arr = array(
array(
'name' => 'food',
'children' => array(
array(
'name' => 'meat',
'children' =>
array(
array('name' => "beef", "children" => NULL),
array("name" => "pork", "children" => NULL)
)
),
array(
'name' => 'friut',
'children' =>
array(
array('name' => "pears", "children" => NULL),
array('name' => "apples", "children" => NULL),
array('name' => "oranges", "children" => NULL)
)
),
array(
'name' => 'veg',
'children' =>
array(
array('name' => "parsnips", "children" => NULL),
array('name' => "carrots", "children" => NULL),
array('name' => "tomatoes", "children" => NULL),
)
)
)
)
);
function display_array($arr, $prefix=""){
while(list($k, $v) = each($arr)){
if(is_array($ca = $arr[$k]['children'])){
display_array($ca, $prefix . $arr[$k]['name'] . ":");
} else {
echo $prefix . $arr[$k]['name'] . "\n";
}
}
}
display_array($arr);
?>
