İki benzer fonksiyonu tek bir sayfada gösterme (yardım)

Merhaba
Elimde birbirine benzeyen 2 kod yapısı var.
1.si
http://nitoz.com/bot/rub.php
<?php

function siteConnect($site)
{

$ch = curl_init();
$hc = "YahooSeeker-Testing/v3.9 (compatible; Mozilla 4.0; MSIE 5.5; Yahoo! Search - Web Search)";
curl_setopt($ch, CURLOPT_REFERER, 'http://www.google.com');
curl_setopt($ch, CURLOPT_URL, $site);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_USERAGENT, $hc);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$site = curl_exec($ch);
curl_close($ch);


// Veriyi parçalama işlemi
preg_match_all('@<span class="arial_26 inlineblock pid-2186-last" id="last_last" dir="ltr">(.*?)</span>@si',$site,$ruble);




echo "Usd TO Ruble: ".$ruble[1][0]."<br />";


}

$giris = siteConnect('https://tr.investing.com/currencies/usd-rub');

?>
2.si
http://nitoz.com/bot/al.php
<?php

function siteConnect($site)
{

$ch = curl_init();
$hc = "YahooSeeker-Testing/v3.9 (compatible; Mozilla 4.0; MSIE 5.5; Yahoo! Search - Web Search)";
curl_setopt($ch, CURLOPT_REFERER, 'http://www.google.com');
curl_setopt($ch, CURLOPT_URL, $site);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_USERAGENT, $hc);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$site = curl_exec($ch);
curl_close($ch);


// Veriyi parçalama işlemi
preg_match_all('@<span class="arial_26 inlineblock pid-49768-last" id="last_last" dir="ltr">(.*?)</span>@si',$site,$ruble);




echo "Aliminyum: ".$ruble[1][0]."<br />";


}

$giris = siteConnect('https://tr.investing.com/commodities/aluminum-historical-data');

?>
Bunları tek tek açtığımda sonuçları veriyor ancak tek bir sayfada göstermek istediğimde php hatası veriyor.
İnculude once ile sadece bir değeri veriyor.


http://nitoz.com/bot/pat.php
<?php
include_once "rub.php";
include_once "al.php";
?>

<?php

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$site = curl_exec($ch);
curl_close($ch);


// Veriyi parçalama işlemi
preg_match_all('@<span class="arial_26 inlineblock pid-'.$id.'-last" id="last_last" dir="ltr">(.*?)</span>@si',$site,$data);
return $data[1][0];

}

$ruble = siteConnect('https://tr.investing.com/currencies/usd-rub',2186);
$Aliminyum = siteConnect('https://tr.investing.com/commodities/aluminum-historical-data',49768);

echo "Usd TO Ruble: ".$ruble."<br />";
