Php 在数组项之间切换

我正在编写一个与外部API接口的应用程序。我们有五个API客户端（为了处理更多的请求——这是API T&C允许的），它们存储在一个数组中。我们还有另一个对象数组，我们使用

foreach

对其执行操作

例如：

$clients = array(
    array(
        "key" => "somekey",
        "secret" => "somesecret"
    ),
    array(
        "key" => "somekey",
        "secret" => "somesecret"
    ),
    array(
        "key" => "somekey",
        "secret" => "somesecret"
    )
);

接下来，我们将处理一组对象：

$objects = array(
    array(
        "info" => "someinfo",
        "url" => "someurl",
        "id" => 1234,
        "more" => "more"
    ),
    array(
        "info" => "someinfo",
        "url" => "someurl",
        "id" => 1234,
        "more" => "more"
    ),
    array(
        "info" => "someinfo",
        "url" => "someurl",
        "id" => 1234,
        "more" => "more"
    )
);

因此，要使用一个API密钥处理它们，我们将执行以下操作：

foreach($objects as $object){
     $class->setAPIKey($clients[0]);
     $result = $class->process($object);
}

为了使用多个键处理它们，我们尝试了以下方法：

$key = 0;
foreach($objects as $object){
    $class->setAPIKey($clients[$key]);
    $result = $class->process($object);
    if($key + 1 == sizeof($clients)){
        $key = 0;
    } else {
        $key++;
    }
}

---

这是可行的，但似乎有点低效。有没有更快/更小的方法来做同样的事情？

您可以这样尝试：

foreach($objects as $key => $object){
     $class->setAPIKey($clients[$key]);
     $result = $class->process($object);
}
