关于php操作oss的问题

这是sdk.class.php中的源代码：
**
     * List Object
     * @param string $bucket (Required)
     * @param array $options (Optional)
     * 其中options中的参数如下
     * $options = array(
     *         'max-keys'     => max-keys用于限定此次返回object的最大数，如果不设定，默认为100，max-keys取值不能大于100。
     *         'prefix'    => 限定返回的object key必须以prefix作为前缀。注意使用prefix查询时，返回的key中仍会包含prefix。
     *         'delimiter' => 是一个用于对Object名字进行分组的字符。所有名字包含指定的前缀且第一次出现delimiter字符之间的object作为一组元素
     *         'marker'    => 用户设定结果从marker之后按字母排序的第一个开始返回。
     * )
     * 其中 prefix，marker用来实现分页显示效果，参数的长度必须小于256字节。
     * @throws OSS_Exception
     * @author xiaobing.meng@alibaba-inc.com
     * @since 2011-11-14
     * @return ResponseCore
     */
    public function list_object($bucket, $options = NULL){
        //options
        $this->validate_options($options);

        if(!$options){
            $options = array();
        }

        //bucket
        $this->is_empty($bucket,OSS_BUCKET_IS_NOT_ALLOWED_EMPTY);

        $options[self::OSS_BUCKET] = $bucket;
        $options[self::OSS_METHOD] = self::OSS_HTTP_GET;
        $options[self::OSS_OBJECT] = '/';
        $options[self::OSS_HEADERS] = array(
        self::OSS_DELIMITER => isset($options[self::OSS_DELIMITER])?$options[self::OSS_DELIMITER]:'/',
        self::OSS_PREFIX => isset($options[self::OSS_PREFIX])?$options[self::OSS_PREFIX]:'',
        self::OSS_MAX_KEYS => isset($options[self::OSS_MAX_KEYS])?$options[self::OSS_MAX_KEYS]:self::OSS_MAX_KEYS_VALUE,
        self::OSS_MARKER => isset($options[self::OSS_MARKER])?$options[self::OSS_MARKER]:'',
        );    
        $response = $this->auth ( $options );
        return $response;
    }

这是我调用后得到的结果如图


我只想得到object的名字和创建时间，请问要怎么剥离出来？

人工置顶！

按照api文檔調用就好啦

public function testListObjectToList()
    {
        $oss = $this->oss;
        $bucket = $this->bucket;
        $prefix = '';
        $marker = '';
        $delimiter = '';
        $next_marker = '';
        $maxkeys = 1;
        while (true)
        {
            $options = array(
                'delimiter' => $delimiter,
                'prefix' => $prefix,
                'max-keys' => $maxkeys,
                'marker' => $next_marker,
            );
            $res = $oss->list_object($bucket, $options);
            $this->assertEquals(200, $res->status);

            $body = $res->body;
            $tmp_object_list = OSSUtil::get_object_list_marker_from_xml($body, $next_marker);
            foreach($tmp_object_list as $object)
            {
                #get object meta
                $res = $oss->get_object_meta($bucket, $object);
                $this->assertEquals(200, $res->status);

            }

            if (empty($next_marker))
            {
                break;
            }
        }
}

    public static function get_object_list_marker_from_xml($xml, &$marker)
    {
        $xml = new SimpleXMLElement($xml);
        $is_truncated = $xml->IsTruncated;
        $object_list = array();
        $marker = $xml->NextMarker;
        foreach ( $xml->Contents as $content) {
            array_push($object_list, $content->Key);
        }
        return $object_list;
    }
