PHP and MongoDB - php

Question

I am trying to connect to MongoDB via PHP.
mongod --version
db version v3.2.8
Then,
php -i | grep mongo
/etc/php/7.0/cli/conf.d/20-mongodb.ini,
mongodb
mongodb support => enabled
mongodb version => 1.1.8
mongodb stability => stable
libmongoc version => 1.3.5
mongodb.debug => no value => no value
I tried:
sudo pecl install mongodb
which returns
pecl/mongodb is already installed and is the same as the released version 1.1.8
install failed
which (the install failed bit) gets redressed if I try:
sudo pecl uninstall mongodb
and
sudo pecl install mongodb
I have this php file:
<?php
echo "I am here";
$connection = new Mongo('localhost');
$db = $connection->mydb;
$list = $db->listCollections();
foreach ($list as $collection) {
echo "$collection </br>";
}
echo "I am never here";
?>
I cannot see the second echo.
I would appreciate any thoughts.
Thank you.

Answer 1

First, check #sanjay comment and then apply this connection:
$db = new MongoClient('mongodb://localhost', [
'username' => 'root',
'password' => '',
'db' => 'YOUR DB'
]);
Hope it will work for you.

Answer 2

I managed to have it working. Thanks to this post:
After upgrading PHP to version 7, why can't I use the mongodb driver?
and this post:
Using the PHP Library for MongoDB (PHPLIB)
Sorry as it seems pretty odd (to me!) but indeed: MongoClient() has become (verbatim! with the slash!) MongoDB\Client().
Hence, the file I had in my original post becomes:
<?php
require 'vendor/autoload.php';
echo "I am here";
$manager = new MongoDB\Client();
$database = $manager->mydb;
foreach ($database->listCollections() as $databaseInfo) {
var_dump($databaseInfo);
}
echo "I managed to arrive here";
?>
and I can see the contents of mydb as well as the 2 echos. The vendor/autoload.php was generated by
sudo composer require "mongodb/mongodb=^1.0.0"
as I ran it from within the directory of the php file above. Probably not the best idea as I, now, have to resolve how to make the autoload.php (and all it carries with) globally available. But, nonetheless, at least, I managed to arrive somewhere.
I am using: PHP 7.0.8-0ubuntu0.16.04.2 (cli) ( NTS )
under: Ubuntu 16.04.1 LTS
