INI file to multidimensional array in PHP

Question

I have the next INI file:

a.b.c = 1
a.b.d.e = 2

I am parsing this file using parse_ini_file. And it returns:

array(
    \'a

It's actually quite simple, you only need to change the format of the array you already have by exploding it's key:

$ini_preparsed = array(
    'a.b.c' => 1,
    'a.b.d.e' => 2
);


$ini = array();
foreach($ini_preparsed as $key => $value)
{
    $p = &$ini;
    foreach(explode('.', $key) as $k)
        $p = &$p[$k];
    $p = $value;
}
unset($p);

print_r($ini);

Output:

Array
(
    [a] => Array
        (
            [b] => Array
                (
                    [c] => 1
                    [d] => Array
                        (
                            [e] => 2
                        )

                )

        )

)
