How to get a array variable value?

$lang['profil_basic_med开发者_StackOverflow中文版eni'] = array( 
    1 => 'Bekâr',
    2 => 'Evli',
    3 => 'Nişanlı',
    4 => 'İlişkide',
    5 => 'Ayrılmış',
    6 => 'Boşanmış'
    );
 $lang['profil_basic_sac'] = array( 
    1 => 'Normal',
    2 => 'Kısa',
    3 => 'Orta',
    4 => 'Uzun',
    5 => 'Fönlü',
    6 => 'Saçsız (Dazlak)',
    7 => 'Karışık/Dağınık',
    8 => 'Her Zaman Bol Jöleli :)'
    );

function sGetVAL($item,$valno) {
  $sonuc = $lang[$item][$valno];
  return $sonuc;
} 

$tempVAL1 = sGetVAL('profil_basic_medeni','3'); // return null
//or
$tempVAL2 = sGetVAL('profil_basic_sac','7'); // return null

$tempVAL1 or $tempVAL2 always return null. why ? how to fix function sGetVAL ???

Because you're using literal indexes like numeric indexes? Because the array $lang is not visible in function?

try this:

$tempVAL1 = sGetVAL('profil_basic_medeni',3); // return null
//or
$tempVAL2 = sGetVAL('profil_basic_sac',7); // return null

and this:

function sGetVAL($item,$valno) {
   global $lang;
   $sonuc = $lang[$item][$valno];
   return $sonuc;
}

your array is global, but your function uses a local version of it (which is different and uninitialized).

either write global $lang first in your function, or use $GLOBALS['lang'] to access the array.

---

$lang is a global variable, that is not visible to sGetVal. Functions can usually only see variables that they define themselves (and Superglobals like $_POST and $_GET).

You could use

function sGetVAL($item,$valno) {
  global $lang;
  $sonuc = $lang[$item][$valno];
  return $sonuc;
}

but it would be better to do without global variables altogether.

The sGetVal function can't see the array $lang as you haven't used the global keyword to bring it into scope. Read here.
