PHP 對 MongoDB 操作

給一個例子，一目瞭然：

<pre name="code" class="html"><?php//$text = "hello the world";//echo $text;// connect//$dburl = '172.29.34.183';//$port= '27017';  $m = new Mongo('172.29.34.183:27017');// select a database$db = $m->ImageList;// select a collection (analogous to a relational database's table)$collection = $db->Tags;// add a record//$obj = array( "title" => "Calvin and Hobbes", "author" => "Bill Watterson" );//$collection->insert($obj);// add another record, with a different "shape"//$obj = array( "title" => "XKCD", "online" => true );//$collection->insert($obj);// find everything in the collection$cursor = $collection->find();$facer = '';$imageurl = '';$imagetags = '';$locationname = '';$locationtag = '';$categary = '';$time = '';$count = 0;foreach ($cursor as $post) {        //$facer[$count]= $post['faceresult'];    $imageurl[$count] = $post['url'];//$http = $post['url'];//print_r($post['url']);    $imagetags[$count] = $post['imagetags'];    $locationname[$count] = $post['locationname'];    $locationtag[$count] = $post['locationtag'];    $categary[$count] = $post['categary'];    $time[$count] = $post['time'];$count = $count+1;}//$imageurl = explode(" ", $imageurl); $no = 90; $random = mt_rand(1, $no); $image = $imageurl[$random]; //$face = $facer[$random];$locname = $locationname[$random];$loctag = $locationtag[$random];$cat = $categary[$random];$imagetime = $time[$random];$imgtag = $imagetags[$random];//輸出結果 echo '<center><img src=" '.$image.'
