(PHP) values of an array - recursion - php

Question

After hours going around in circles I gave up and ask for help.
I have an array which looks like:
[field01] => Array
(
[name] => test01
[prefix] => C01
)
[field02] => Array
(
[url] => http://www.url.com
[user] => a_user
[password] => a_password
)
[filed03] => Array
(
[0] => Array
(
[id] => 1
[Type] => standard
[Name] => name
)
[1] => Array
(
[id] => 5
[Type] => standard
[Name] => name
)
)
Now I want to go through that array and get the following output as a return from a recursive function:
Array (
[0] = "The values of field01: name, prefix - test01, C01"
[1] = "The values of field02: url, user, password - http://www.url.com, a_user, a_password"
[2] = "The values of field03: id, Type, Name - 1, standard, name"
[3] = "The values of field03: id, Type, Name - 5, standard, name"
)
I have tried it with a recursive function but stuck with field03 to save the name.
Any help for that?
UPDTAE:
here is the array, so you don't have to write it:
$data['field01']['name'] = "field01";
$data['field01']['prefix'] = "C01";
$data['field02']['url'] = "http://www.url.com";
$data['field02']['user'] = "a_user";
$data['field02']['password'] = "a_password";
$data['field03'][0]['List_id'] = 1;
$data['field03'][0]['Type'] = "standard";
$data['field03'][0]['Name'] = "name";
$data['field03'][1]['List_id'] = 5;
$data['field03'][1]['Type'] = "standard";
$data['field03'][1]['Name'] = "name";
Thanks in advance!

<?php
$data['field01']['name'] = "field01";
$data['field01']['prefix'] = "C01";
$data['field02']['url'] = "http://www.url.com";
$data['field02']['user'] = "a_user";
$data['field02']['password'] = "a_password";
$data['field03'][0]['List_id'] = 1;
$data['field03'][0]['Type'] = "standard";
$data['field03'][0]['Name'] = "name";
$data['field03'][1]['List_id'] = 5;
$data['field03'][1]['Type'] = "standard";
$data['field03'][1]['Name'] = "name";
$text = '';
foreach ($data as $k => $fields) {
if (isset($fields[0])) {
foreach ($fields as $field) {
$text .= 'The values of ' . $k . ': ' . traverse($field) . "\n";
}
} else {
$text .= 'The values of ' . $k . ': ' . traverse($fields) . "\n";
}
}
echo $text;
function traverse($fields) {
$keys = array_keys($fields);
$values = array_values($fields);
return implode(', ', $keys) . ' - ' . implode(', ', $values);
}
?>

This assumes if there is an array of arrays, it is all arrays. In other words, you aren't mixing strings with arrays.
$resultArray = array();
function process($inputArray, $fieldName) {
$result = array();
$keys = array_keys($inputArray);
if (!is_array($inputArray[0])) {
$result[] = "The value of $fieldName: ".implode($keys,', '). ' - '. implode($inputArray, ', ');
} else {
foreach($inputArray as $arr) {
$result = array_merge($result, process($arr, $fieldName));
}
}
return $result;
}
foreach($data as $k=>$v) {
$processed = process($v, $k);
$resultArray = array_merge($resultArray, $processed);
}
print_r($resultArray);
