protected $usernameList = array();

protected $userEarnings = array();

public function getUserEarnings($date, $serviceUsername) {
if (empty($this->userEarnings[$date][$serviceUsername])) {
    $this->curl->getContent('hidden link', Curl::POST, array(
    'performer' => $serviceUsername,
    'stat' => 'Statystyka'
    ));

    $content = $this->curl->getContent('hidden link' . date('Y-m-d', strtotime($date)) . '&params[endDate]=' . date('Y-m-d', strtotime($date)));

    preg_match('#<span class="payout">([0-9\.]+) USD</span>#si', $content, $matches);

    $this->userEarnings[$date][$serviceUsername][] = array(
    'statDatetime' => date('Y-m-d ', strtotime($date)) . date('H:i:s'),
    'statEarnings' => (float) $matches[1]
    );
}

return (!empty($this->userEarnings[$date][$serviceUsername])) ? $this->userEarnings[$date][$serviceUsername] : array();
}

public function getUsernameList() {
if (empty($this->usernameList)) {
    $pageNumber = 1;
    do {
    $content = $this->curl->getContent('hidden link' . $pageNumber . '|1|1&filter=A');
    preg_match_all('#<form id="performer_([^"]+)" action="hidden link', $content, $matches);
    $this->usernameList = array_merge($this->usernameList, $matches[1]);

    $pageNumber++;
    } while (count($matches[1]) == 5);
}

return $this->usernameList;
}

public function logIn($userName, $userPassword) {
$this->curl->getContent('hidden link');

$content = $this->curl->getContent('hidden link');
preg_match('#<input type="hidden" name="ref" value="([^"]*)">#Usi', $content, $matches);

$content = $this->curl->getContent('hidden link', Curl::POST, array(
    'studio' => $userName,
    'password' => $userPassword,
    'ref' => $matches[1],
    'Submit' => 'Zalogowanie tutaj'
    ));
}

public function logOut() {
$this->curl = new Curl();
}

}

   ?>

你的意思是：

'statEarnings' => floatval($matches[1])
