The current(); function would return the first value;

echo current($array);

I think you mean to use the current 'exposed' offset as your functions' arguments:

foreach($frequency as $i) {        
   showphp_AlexVortaro (getphp_AlexVortaro($i));
   showphp_Smartfm(getphp_Smartfm($i));        
}

or:

for($i=0; $i<count($frequencies); $i++) {        
   showphp_AlexVortaro(getphp_AlexVortaro($frequencies[$i]));
   showphp_Smartfm($frequencies[$i]);        
}

$i is the value of your array in the foreach loop. Instead of sending $frequency[$i] you must use '$i'.

If you want to fetch the keys use the following construction:

foreach ($array as $key => $value) 
{
 // Do something
}
