Question

Ive the following Code , a function take a list of usernames and put in them in array then execute function called function get_all_friends , Code works fine and no error , my question here how to adjust the code if ive bulk of usernames lets say like 10k ?

Like reading from file include all usernames name and put them in array using

$file_handle = fopen("users.txt")

please advise !

<?PHP
    $user1 = "usernamehere";
    $user2 = "usernamehere";
    $user3 = "usernamehere";
    $u[] = $user1;
    $u[] = $user2;
    $u[] = $user3;

    function get_all_friends($users) 
    {
        $connection = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET, TOKEN_KEY, TOKEN_SECRET);
        $list = array();
        foreach($users as $user)
        {
            $result = $connection->get( 'friends/ids', array(
            "screen_name"=> $user)
            );

            foreach($result->ids as $friend) 
            {
                $list[] = $friend;
            }

        }
        return $list;
    }

    //call the function
    $result = get_all_friends($u);

    foreach($result as $res)
    {
        $query = "INSERT INTO friends (userid, name, grade, flag) VALUES ($res, 'name', 100, 0 ) ";
        mysql_query($query);    
    }

    //to print the databse result
    echo "row<br />";
    $res = mysql_query("SELECT * FROM friends");  
    while ($row = mysql_fetch_assoc($res)) 
    {
        print_r($row);
    }
?>

Something like the following should work (untested):

$filename = "users.txt";
$file_handle = fopen($filename, "r");
$contents = fread($file_handle, filesize($filename));
$usernames = preg_split("/ (,|\\n) /", $contents);
fclose($file_handle);

The usernames must be separated by a comma or a new line.

Although, if you are positive that the usernames will only be separated by a new line OR a comma, this code will be faster:

$filename = "users.txt";
$file_handle = fopen($filename, "r");
$contents = fread($file_handle, filesize($filename));
// new line:
$usernames = explode("\n", $contents);
// or comma:
$usernames = explode(",", $contents);
fclose($handle);

Please choose only one of the $usernames definitions.
