how to use php with ini files

Question

My php Code here

 <?php
    function String($word){


            $lang = parse_ini_file("../pard_language/en/language.ini");

        $key = array_search($word, $lang); 
        if(isset($key)){
        echo $key;

        }
        }


     echo String("PARD_INSTALL");
    ?>

my language.ini file is this

PARD_INSTALL = Install
PARD_USER_AGGREMENT = User Aggrement
PARD_AGREE = Agree
PARD_HOST_NAME = Host Name
PARD_DATA_BASE = Data Base
PARD_DATA_BASE_USER =  Data Base User
PARD_DATA_BASE_USER_PASS_WORD =  Data Base User Password
PARD_CONNECT = Connect
PARD_RESET = Reset
PARD_ADMIN_USER_NAME =  Admin User Name
PARD_ADMIN_USER_PASS_WORD =  Admin User Password
PARD_LOGIN = Login

This my above code is not working.I want to keep a ini file which contain language contain and need to get the word value using above php function.This codes not give any output.please help me to solve this ?

Answer 1

You are searching for values not getting the key, parse_ini_file would return an array of all elements so with $lang[$word] you should get the values you want ...

function String($word) {
    $lang = parse_ini_file("../pard_language/en/language.ini");
    return isset($lang[$word]) ? $lang[$word] : null ;
}

Now that is still a BAD Approach why ?

• You have to call parse_ini_file every time you want a which loads the files every time
• String is a bad name for a function
• echo was called twice .. 1. In the function and outside the function insted of using return

Here is what i would use :

$ini = new ArrayINI("../pard_language/en/language.ini");
echo $ini("PARD_INSTALL");
// or
echo $ini['PARD_INSTALL'];

Because i also extended IteratorAggregate i can loop all the values

foreach ( $ini as $k => $value ) {
    var_dump($k . " = " . $value);
}

Class Used

class ArrayINI implements ArrayAccess, IteratorAggregate {
    private $lang;

    public function __construct($ini) {
        $this->lang = parse_ini_file($ini);
    }

    function __invoke($offset) {
        return $this->offsetGet($offset);
    }

    public function getIterator() {
        return new ArrayIterator($this->lang);
    }

    public function offsetSet($offset, $value) {
        if (is_null($offset)) {
            $this->lang[] = $value;
        } else {
            $this->lang[$offset] = $value;
        }
    }

    public function offsetExists($offset) {
        return isset($this->lang[$offset]);
    }

    public function offsetUnset($offset) {
        unset($this->lang[$offset]);
    }

    public function offsetGet($offset) {
        return isset($this->lang[$offset]) ? $this->lang[$offset] : null;
    }
}
