Getting Started with MongoDB and PHP

This tutorial provides an introduction to basic database operations using the mongo shell. MongoDB is a document database that provides high performance, high availability, and easy scalability.

MongoDB is a free and open-source cross-platform document-oriented database program with NoSQL database. It stores data in json format. MongoDb is developed by MongoDB Inc in 2007.

How Access MongoDB from PHP

To access MongoDB from PHP you need:

1) The MongoDB server running. The server is the “mongod” file,
not the “mongo” client (note the “d” at the end).
2) The MongoDB PHP driver installed.

Make a connection string & Select a database

To make connection string & select the database in php simply used the below snippets.
Create a config.php file.

<?php
#connect to mongodb
   $m = new MongoClient();
   echo "Connection with database is successful.";
#select a database
   $db = $m->mydb;
   echo "Database mydb selected";
?>

<?php

#connect to mongodb

$m = new MongoClient();

echo "Connection with database is successful.";

#select a database

$db = $m->mydb;

echo "Database mydb selected";

Select all Data

<?php
#include the connect file
required("config.php");
#Select all data
   $all = $collection->find();
   foreach ($all as $document) 
   {
      echo $document["name"] . "\n";
   }

?>

<?php

#include the connect file

required("config.php");

#Select all data

$all = $collection->find();

foreach ($all as $document)

{

echo $document["name"] . "\n";

}

Delete Data

In the part of useful CRUD there is ability to delete the data records. MonogoDB provides a method remove() for this which only takes an array of data attributes as the criteria to removing the data records.

<?php
#include the connect file
   required("config.php");
#Now remove the document
   $collection->remove(array("title"=>"MongoDB Tutorial"),false);
   echo "Documents deleted successfully";
   
#Now display the available data
   $cursor = $collection->find();
#Iterate cursor to display name of data
   echo "Updated document";
   foreach ($cursor as $document) {
      echo $document["name"] . "\n";
   }
?>

<?php

#include the connect file

required("config.php");

#Now remove the document

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

echo "Documents deleted successfully";

#Now display the available data

$cursor = $collection->find();

#Iterate cursor to display name of data

echo "Updated document";

foreach ($cursor as $document) {

echo $document["name"] . "\n";

}

Update the data

In the CRUD operations there is also ability to update the records. In MongoDB have a simple method save() for this which require an array of criteria to know which records would be updated. Bellow is the example fo updating the data records.

<?php
#Update the data
   $collection->update(array("title"=>"MongoDB"), array('$set'=>array("title"=>"MongoDB Tutorial")));
   echo "Document updated successfully";
#Now display the updated data
   $cursor = $collection->find();
#Iiterate cursor to display name of data
   echo "Updated document";
   foreach ($cursor as $document) {
      echo $document["name"] . "\n";
   }
?>

<?php

#Update the data

$collection->update(array("title"=>"MongoDB"), array('$set'=>array("title"=>"MongoDB Tutorial")));

echo "Document updated successfully";

#Now display the updated data

$cursor = $collection->find();

#Iiterate cursor to display name of data

echo "Updated document";

foreach ($cursor as $document) {

echo $document["name"] . "\n";

}
