php variables inside functions vs outside [duplicate]

Question

Possible Duplicate:
php function variable scope

is there any reason i can't push these variables in the function? if i do this

//function scraping_for_text_2
for($i=0; $i<$l; $i++) { 
echo "$contents[$i]";
echo "$fnamearray[$i].torrent";
}

it echoes back the correct vaules

but when i have an function like this

function scraping_for_text_2($iUrl,$iText)

$curl = curl_init();

curl_setopt($curl, CURLOPT_URL, $uploadurl);
curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($curl, CURLOPT_VERBOSE, 1);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($curl, CURLOPT_COOKIEFILE, 'cookies.txt');
curl_setopt($curl, CURLOPT_POST, true);
 curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE); 
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
$curlresult = curl_exec($curl);
curl_close ($curl);
                      $data = array( 

"description" => "testing",
"torrent" => "@$fnamearray[$i]",
"submit" => "Upload"
);

i get this Notice: Undefined variable: fnamearray Notice: Undefined variable: i in

pass them as arguments into your function! you can also access them via the globals or $GLOBALS but i wouldn't recommend it. — mpen

It is called scope. It is good. You can abuse it with things like global's but should not. — ficuscr

You might want to learn basic concepts such as variable scoping before getting too involved in any programming language.

In this case, your variables simply aren't defined inside the function.
