Question

I would like to make use of somehting like [parse_ini_file][1].

Lets say for instance I have a boot.ini file that I will load for further procedure:

Answer 1

Well, you need to postprocess the parse_ini_file result array then.

$ini_array = parse_ini_file("bootstrap.ini");

$ini = new stdclass;
foreach ($ini_array as $key=>$value) {
    $c = $ini;
    foreach (explode(".", $key) as $key) {
        if (!isset($c->$key)) {
            $c->$key = new stdclass;
        }
        $prev = $c;
        $c = $c->$key;
    }
    $prev->$key = $value;
}

Update Hackety-Hack. Now using an extra $prev to unset the last object level again. (A for loop to detect the last $key would have worked better).

If you want to use the array syntax and the object syntax, then replace the new stdclass with new ArrayObject(array(), 2);.

Answer 2

I got an elegant solution for you. This implementation allows inheritance and vectors using dots as our collegue "zerkms" showed us before. In truth, I took his solution and improved it. Thus the solution be like Zend Parser :) I tested it and works. But, as we know, is impossible test all possibilities. Then, I hope attent people detect troubles and propose corrections.

Here goes the code (as a function):

function parse($filename) {

        $ini_array = parse_ini_file ( $filename, true );

        if (! $ini_array)
            throw new Exception ( 'Error on parsing ini file!', - 1 );

        $ini = new stdClass ();

        //Parse section...
        foreach ( $ini_array as $namespace => $prop ) {

            $section = $namespace;
            $ext = explode ( ':', $namespace );

            if (count ( $ext ) == 2) {

                $section = trim ( $ext [0] );
                $extend = trim ( $ext [1] );

                if (! isset ( $ini->$extend ))
                    throw new Exception ( 'Parent section doesn\'t exists!', - 1 );

                $ini->$section = clone $ini->$extend;

            } else
                $ini->$section = new stdClass ();

            foreach ( $prop as $key => $value ) {

                $arr = explode ( '.', $key );
                $n = count ( $arr ) - 1;

                if ($n) {
                    $aux = $ini->$section;
                    for($i = 0; $i < $n; ++ $i) {

                        if(!isset($aux->$arr [$i]))
                            $aux->$arr [$i] = new stdClass ();

                        $aux = $aux->$arr [$i];
                    }
                    $aux->$arr [$n] = $value;
                } else
                    $ini->$section->$key = $value;

            }

        }

        return $ini;

}

And here goes an example of .ini file:

[environment]
env_name = production
x.y = 3

[oi : environment]
z = 5

$ini_array = parse_ini_file("sample.ini");

$ini = new stdclass;
foreach ($ini_array as $key => $value) {
    $last = substr(strrchr($key, '.'), 1);
    if (!$last) $last = $key;

    $node = $ini;

    foreach (explode('.', $key) as $key2) {
        if (!isset($node->$key2)) {
            $node->$key2 = new stdclass;
        }

        if ($key2 == $last) {
            $node->$key2 = $value;
        } else {
            $node = $node->$key2;
        }
    }

}

var_dump($ini->db->host1->type);
