Need help with array()

OK, so i have this class:

PHP Code:


		
			
<?php

class Lang extends Db {

    var $lang = array();

    var $chosen_lang;

    var $lang_dir;

    var $img_dir;

    

    function setLang ($chosen_lang) {

        $this->lang_dir = $_SERVER['DOCUMENT_ROOT'].'/lang/'.$this->chosen_lang.'/';

        $this->img_dir = $_SERVER['DOCUMENT_ROOT'].'/gl_imgs/'.$this->chosen_lang.'/';

        $this->chosen_lang = $chosen_lang;

        

        unset($chosen_lang);

    }

    

    public function loadLang ($file){

        if( file_exists( $_SERVER['DOCUMENT_ROOT'].'/lang/'.$this->chosen_lang.'/'.$file.'.php' ) ) {

            include( $_SERVER['DOCUMENT_ROOT'].'/lang/'.$this->chosen_lang.'/'.$file.'.php' );

            $this->lang[$file] = array();

                

            foreach ($lang as $k => $v) {

                $this->lang[$file][$k] = $v;

            }

        }

        

        unset($lang, $file, $k, $v);

    }

}

?>

And on the index page of the website i have this:

PHP Code:


		
			
<?php

include($_SERVER['DOCUMENT_ROOT'].'classes/class_Db.php');

include($_SERVER['DOCUMENT_ROOT'].'classes/class_Lang.php');



$lang = new Lang;

$lang->setLang('en-us');

$lang->loadLang('website_account');

$lang->loadLang('website_main-menu');

?>

My question is: why the script won't work if i add the command:

PHP Code:


		
			
$lang->loadLang('website_main-menu');

If i only leave the following, the script works as intended:

PHP Code:


		
			
$lang = new Lang; 

$lang->setLang('en-us'); 

$lang->loadLang('website_account');

After some debugging, i found out that the script executes the first loadLang command on the 'website_account', but when it executes the second loadLang command ('website_main-menu'), it freezes at this line on the class:

PHP Code:


		
			
$this->lang[$file] = array();

Thanks in advance!

I am guessing is a mixture of document_root and unsetting the $chosen_lang. There is ambiguity in which one you are unsetting since the class's property is named the same and can be access the same. document_root sometimes doesn't work right, that has been my experience, instead I use dirname(__FILE__) for that.
And using var to set class properties is deprecated, you can use public, private, or protected. you can leave it just like that e.g. $lang=array(); and it will default to public.

I am guessing the problem is that it can't include the right file or maybe that file has something that is causing the freezing in this line include( $_SERVER['DOCUMENT_ROOT'].'/lang/'.$this->chosen_lang.'/'.$file.'.php' );

Oh, yes yes... i found the bug. Thanks a lot, :P.

The problem was that the included file was like this:

PHP Code:


		
			
<?php
$lang = array(
    'home' => 'Home'
    'contact' => 'Contact'
    'aboutus' => 'About Us'
    'games' => 'Games'
    'movies' => 'Movies'
    'tv' => 'TV'
    'music' => 'Music'
);
?>

The problem was that i forgot to separate the indexes with the comma, that was why one file was working (had commas) and the other wasn't (no commas). It should look like this:

PHP Code:


		
			
<?php
$lang = array(
    'home' => 'Home',
    'contact' => 'Contact',
    'aboutus' => 'About Us',
    'games' => 'Games',
    'movies' => 'Movies',
    'tv' => 'TV',
    'music' => 'Music'
);
?>

Thanks, :D!

BTW, i'll take a look at those problems you mentioned... ^^

Great that you find the problem, good thing it wasn't the constructing the lang path. I didn't mean to look like big problems, it is just a have a pet peeve with ambiguities in codes
