You can turn the contents of the file into a regular expression that matches any of the strings.

$ex_cont = file("ben.txt", FILE_IGNORE_NEW_LINES);
$isbanned = false;
$regex = '/^!sa (' . implode('|', array_map('preg_quote', $ex_cont)) . ')/';
if (preg_match($regex, $message)) {
    $isbanned = true;
    sendMessage($chatId, "<b>Number Banned!</b>");
}
