(PHP) values of an array - recursion

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!

• Dave: Post some of the code you've attempted.
• Talisin: Hi Dave. I've tried a lot of ways on paper and as code. I can post you one but I guess it will confuse more as it helps. And Ivan already post a possible code. :) Thanks

<?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);
