Most likely I'm doing this wayyyyyy too complicated. But I'm in the need of converting multiple arrays to multidimensional array key's. So arrays like this:
Array //$original
(
[0] => 500034
[1] => 500035 //these values need to become
//consecutive keys, in order of array
)
Needs to become:
Array
(
[50034][50035] => array()
)
This needs to be done recursively, as it might also require that it becomes deeper:
Array
(
[50034][50036][50126] => array() //notice that the numbers
//aren't necessarily consecutive, though they are
//in the order of the original array
)
My current code:
$new_array = array();
foreach($original as $k => $v){ //$original from first code
if((gettype($v) === 'string' || gettype($v) === 'integer')
&& !array_key_exists($v, $original)){ //check so as to not have illigal offset types
$new_array =& $original[array_search($v, $original)];
echo 'In loop: <br />';
var_dump($new_array);
echo '<br />';
}
}
echo "After loop <br />";
var_dump($new_array);
echo "</pre><br />";
Gives me:
In loop:
int(500032)
In loop:
int(500033)
After loop
int(500033)
Using this code $new_array =& $original[array_search($v, $original)];
I expected After loop: $new_array[50034][50035] => array()
.
What am I doing wrong? Been at this for hours on end now :(
EDIT to answer "why" I'm trying to do this I'm reconstructing facebook data out of a database. Below is my own personal data that isn't reconstructing properly, which is why I need the above question answered.
[500226] => Array
(
[own_id] =>
[entity] => Work
[name] => Office Products Depot
[500227] => Array
(
[own_id] => 500226
[entity] => Employer
[id] => 635872699779885
)
[id] => 646422765379085
)
[500227] => Array
(
[500228] => Array
(
[own_id] => 500227
[entity] => Position
[id] => 140103209354647
)
[name] => Junior Programmer
)
As you can see, the ID [500227]
is a child of [500226]
, however, because I haven't got the path to the child array, a new array is created. The current parentage only works to the first level.
[own_id]
is a key where the value indicates which other key should be its parent. Which is why the first array ([500226]
) doesn't have a value for [own_id]
.
