Steps of Mongodb with PHP Connectivity.

Mongodb with PHP Connectivity

Make a Connection and Select a Database

<?php

  // connect to mongodb

  $m = new MongoClient();

  echo "Connection to database successfully";

  // select a database

  $db = $m->examplesdb;

  echo "Database examplesdb selected";

?>

Create a Collection

<?php

  // connect to mongodb

  $m = new MongoClient();

  echo "Connection to database successfully";

  // select a database

  $db = $m->examplesdb;

  echo "Database examplesdb selected";

  $collection = $db->createCollection("examplescol");

  echo "Collection created succsessfully";

?>

Insert a Document

<?php

  // connect to mongodb

  $m = new MongoClient();

  echo "Connection to database successfully";

  // select a database

  $db = $m->examplesdb;

  echo "Database examplesdb selected";

  $collection = $db->examplescol;

  echo "Collection selected succsessfully";

  $document = array(

  "title" => "MongoDB",

  "description" => "database",

  "likes" => 100,

  "url" => "http://www.data-flair.training/mongodb/",

  "by" => "data flair"

 );

$collection->insert($document);

echo "Document inserted successfully";

?>

Find All Documents

<?php

  // connect to mongodb

  $m = new MongoClient();

  echo "Connection to database successfully";

  // select a database

  $db = $m->examplesdb;

  echo "Database examplesdb selected";

  $collection = $db->examplescol;

  echo "Collection selected succsessfully";

  $cursor = $collection->find();

  // iterate cursor to display title of documents

  foreach ($cursor as $document) {

  echo $document["name"] . "\n";

 }

?>

Update a Document

<?php

   // connect to mongodb

   $m = new MongoClient();

   echo "Connection to database successfully";

   // select a database

   $db = $m->examplesdb;

   echo "Database examplesdb selected";

   $collection = $db->examplescol;

   echo "Collection selected succsessfully";

   // now update the document

   $collection->update(array("name"=>"MongoDB"),

   array('$set'=>array("name"=>"MongoDB Tutorial")));

   echo "Document updated successfully";

   // now display the updated document

   $cursor = $collection->find();

   // iterate cursor to display title of documents

   echo "Updated document";

   foreach ($cursor as $document) {

   echo $document["name"] . "\n";

 }

?>

Delete a Document

<?php

   // connect to mongodb

   $m = new MongoClient();

   echo "Connection to database successfully";

   // select a database

   $db = $m->examplesdb;

   echo "Database examplesdb selected";

   $collection = $db->examplescol;

   echo "Collection selected succsessfully";

   // now remove the document

   $collection->remove(array("name"=>"MongoDB Tutorial"),false);

   echo "Documents deleted successfully";

   // now display the available documents

   $cursor = $collection->find();

   // iterate cursor to display title of documents

   echo "Updated document";

   foreach ($cursor as $document) {

   echo $document["name"] . "\n";

 }
