Delivery

Work in your own git and send us a link to your repo.

Restrictions

You should use vanilla PHP without any framework.

The assignment

Given the file "config.txt", with the following content:

---

# Main configuration file
db.host = "10.0.0.55"
db.port = 3306
db.name.internal = "db­01­internal.local" 
db.name.external = "db­01.company.tld"

cache.ttl = 3600

debug.enabled = false
##### NOTE: keep the connection timeout low cache.connection.timeout = 3

Create a function that reads & converts the above file into a multi­dimensional array. The parser should be able to handle unlimited numbers of levels in the config.

The output should yield exactly the following when run through var_dump():

    array(3) { 
        ["db"]=> 
        array(3) {
            ["host"]=> 
            string(9) "10.0.0.55" 
            ["port"]=> 
            int(3306) 
            ["name"]=> 
            array(2) {
            ["internal"]=>
            string(20) 
                "db­01­internal.local" 
            ["external"]=>
                string(17) "db­01.company.tld"                                     
            } 
        }
        ["cache"]=> 
        array(2) {
            ["ttl"]=> 
            int(3600) 
            ["connection"]=> 
            array(1) {
                ["timeout"]=>
                int(3) 
            }
        } 
        ["debug"]=> 
        array(1) {
            ["enabled"]=>
            bool(false) 
        }
    }
