PHP操作mongodb: PHP 要操作mongodb需要打模块 官网可以下载:http://pecl.php.net/package/mongo 下载 mongodb设置成用户授权的启动方式 php手册没有些用户授权方式登陆的方法: conn.php ?php $conn = new Mongo(mongodb://user1:123456@localhost:27017/t
PHP操作mongodb:";<br> print_r($val['name']); //取id的话 得"_id"<br> }<br> <br> 例子2:指定值查询<br> $arr = array("name"=>"user1"); //查询nam=user1的<br> $rst = $c1->find($arr);<br> foreach($rst as $val){<br> echo "<pre class="brush:php;toolbar:false">";<br> $fis = $val['_id'];<br> print_r($val);<br> echo "<a href="'user.php?fid=%7B%24fid%7D'"></a>"; //你会发现fid传到user.php的时候变成字符串了,怎么解决?<br> //user.php 根据_id查mongodb对应的数据<br> <?php <br /> include "conn.php";<br> $c1 = $db->c1;<br> $oid= new MongoId($_GET['fid']); 用这个转一下<br> var_dump($oid); //还是Object,不转的话就是string类型<br> <br> $arr = array("_id"=>"$oid");<br> $rst = $c1->find($arr);<br> foreach($rst as $val){<br> echo "<pre class="brush:php;toolbar:false">";<br> print_r($val);<br> }<br> ?><br> }<br> <br> 例子3:增加<br> include "conn.php";<br> $c1 = $db->c1;<br> //db.c1.insert({"name"=>"user3",age:30,"sex"=>"nan"});<br> $arr = array("name"=>"user3","age"=>30,"sex"=>"nan");<br> if($c1->insert($arr))<br> echo '成功';<br> else<br> echo '失败';<br> <br> 例子4:删<br> include "conn.php";<br> $c1 = $db->c1;<br> //db.c1.remove({"name"=>"user2"});<br> $arr = array("name"=>"user2");<br> if($c1->remove($arr))<br> echo '删除成功';<br> else<br> echo '删除失败';<br> <br> 例子4:改<br> include "conn.php";<br> $c1 = $db->c1;<br> //db.c1.update({"name"=>"user2"},{$set:{age:20,sex:"nan"}}); 增加字段<br> $sarr = array("name"=>"user2");<br> $darr = array('$set'=>array('sex'=>'nan','age'=>24));<br> $opts = array('upsert'=>0,'multiple'=>1);<br> if($c1->update($sarr,$darr,$opts)) //php里面的update只能传3个参数<br> echo '更改成功';<br> else<br> echo '更改失败';<br> <br> //关闭<br> $conn->close();<br> ?>
