php Class ‘MongoClient’ NOT Found

[qq_25091119]

windows下为php7.0.4安装目前官方版本对应的最新的php_mongodb.dll扩展，该扩展版本为1.1.6，支持最高版本MongoDB3.2，支持php7.0,；在phpinfo中可以看到MongoDB扩展，如图
但是在没有使用命名空间的情况下，new MongoClient();出现如下错误
Fatal error: Uncaught Error: Class 'MongoClient' not found in E:\.......... 这是为什么？？请问

版本支持如下图（注意mongodb1.1那一行）
1、扩展对MOngoDB版本的支持


2、扩展对php版本的支持

找到原因了，是因为旧版的php_mongo.dll才是使用MongoClient类来实现连接，新版的php_mongodb.dll是使用 MongoDB\Driver\Manager来连接的；注意该类命名空间不能省略。 这是旧版的参考文档 http://php.net/manual/zh/book.mongo.php 这是新版的参考文档 http://php.net/manual/zh/book.mongodb.php 下面是新版的使用方法：

	$con    = new MongoDB\Driver\Manager('mongodb://127.0.0.1:27017');
	$query  = new MongoDB\Driver\Query([]);
	$cursor = $con->executeQuery('databaseName.collectionName',$query);
	$it     = new IteratorIterator($cursor);
	$it->rewind();
	while ($doc=$it->current()) {
		print_r($doc);
		$it->next();
		echo '<br/>';
	}

没用过，不好说 不过你怎么知道就一定有 MongoClient 类呢？ 你至少需要 print_r(get_extension_funcs('mongodb')); 看一下该扩展中提供了那些函数 print_r(get_declared_classes()); 看一下预定义类中是否有你需要（或相似）的类名

php.net的官方文档是这么用的new MongoClient() 我也不清楚是否有这类，是不是我没有安装对应的VC？ vc14的下载地址是什么，怎么在网上找不到

我不是让你看一下吗？ 手边的事情就那么难？

上面是修改那个文档

非常感谢楼主，原来新版不一样了。现在网上查到的资料几乎都是用的旧方法。看来还是得看官方文档才对！
