Splitting keys from values into another array - php

Question

I have a function to convert a .json file to an array:
function jsonToArray($file) {
$json = json_decode(file_get_contents($file), true);
print_r($json); }
This yields an array like this:
Array (
[field1] => value1
[field2] => Array
(
[subfield1] => subvalue1
[subfield2] => subvalue2
[subfield3] => subvalue3
)
)
To interface with existing code, I need these arrays with the fields and values split, like this:
Array (
[0] => Array
(
[0] => field1
[1] => Array
(
[0] => subfield1
[1] => subfield2
[2] => subfield3
)
)
[1] => Array
(
[0] => value1
[1] => Array
(
[0] => subvalue1
[1] => subvalue2
[2] => subvalue3
)
)
)
The code I came up with works if this structure is maintained for all usage but as that can't be guaranteed I need another solution. I'm sure it's something relatively simple, I just can't crack it. Any hints or insight would be much appreciated.

Answer 1

try this code
$arr = array ('field1' => 'value1',
'field2' => array(
'subfield1' => 'subvalue1',
'subfield2' => 'subvalue2',
'subfield3' => 'subvalue3'));
function array_values_recursive($ary) {
$lst = array();
foreach( $ary as $k => $v ) {
if (is_scalar($v)) {
$lst[] = $v;
} elseif (is_array($v)) {
$lst[] = array_values_recursive($v);
}
}
return array_values($lst);
}
function array_keys_recursive($ary) {
$lst = array();
foreach( $ary as $k => $v ) {
if (is_scalar($v)) {
$lst[] = ($k);
} elseif (is_array($v)) {
$lst[] = array_keys_recursive($v);
}
}
return $lst;
}
echo '<pre>';
$arr1 = array();
$arr1[] = array_values_recursive($arr);
$arr1[] = array_keys_recursive($arr);
print_r($arr1);

Answer 2

This might be useful to you: array_values() and array_keys() that and a little of foreach would do the magic.
