How to 'decode' array?

Question

I have an .ini file. This is what an .ini file looks like:

[something]
a = b
c = d
e = f
g = h

I have the following PHP code:

$ini = parse_ini_file("data.ini", true);
print_r($ini);

The output is:

Array
(
    [something] => Array
        (
            [a] => b
            [c] => d
            [e] => f
            [g] => h
        )

)

Is there a way to 'decode' the array? For example, that the output is this:

a => b
c => d
e => f
g => h

Thanks!

$ini['something']? Looks like parse_ini_file also gives you the sections. — Balázs Édes

The array is "decoded" from the INI file and should be used as-is, as a Map (perhaps with iteration of the key/value pairs). $ini["a"] // => "b". See a tutorial/reference, eg. oreilly.com/catalog/progphp/chapter/ch05.html , php.net/manual/en/language.types.array.php — user2864740

Decode what has just been decoded, thats an interesting question. — Havenard

Like this :

$ini = parse_ini_file("data.ini", true);


foreach ($ini['something'] as $key => $value) {
    echo $key . " => ". $value."<br />";
}

OUTPUT

a => b
c => d
e => f
g => h

That works, but I still see Array ( [something] => Array ( [a] => b [c] => d [e] => f [g] => h ) ). After that I just see a => b etc.

@WilliamDavidEdwards, I can't help but I feel that you simply copy/pasted the code above without actually understanding it. Try to figure out what's going on first and then you can actually get the desired output.

@WilliamDavideEdwards Because $ini is an array containing other arrays. Try print_r($ini['something']) you will understand.

Its same as mentioned in php page

<?php
$fruit = array('a' => 'apple', 'b' => 'banana', 'c' => 'cranberry');

reset($fruit);
while (list($key, $val) = each($fruit)) {
    echo "$key => $val\n";
}
?>

I don't understand how this works with .ini files.

reset(), list() and each(). R.I.P. foreach.
