PHP 7.0中未定义的函数reg_open_key（）

Question

我尝试访问Windows注册表但显示错误。有什么建议？

我正在使用PHP 7.0。

<?php
    // device instance ID
    $id = "0060E049DF74EC311000711F";


    $keyConst = 'HKEY_LOCAL_MACHINE';
    $key = "SYSTEM\CurrentControlSet\services\USBSTOR\Enum";

    if (!($reg = reg_open_key($keyConst, $key))) {
        throw new Exception("Cannot access registry.");
    }

    $found = false;
    $numDevices = reg_get_value($reg, "Count");
    for ($i = 0; $i < $numDevices; $i++) {
        $value = reg_get_value($reg, $i);
        if (strpos($val, $id) !== false) {
            $found = true;
            break;
        }
    }    
    reg_close_key($reg);

    echo "USB drive dongle ", ($found) ? "found" : "not found";

?>
