What is SFTP

SFTP, Secure File Transfer Protocol, is more applicable these days where cyber security is at its peak. Whenever possible, one has to use SFTP as the communications are encrypted.

Most of tools that are used for FTP like filezilla allows using SFTP with minor adjustment. SFTP has to be supported by the server that is providing the FTP server and usually uses different port than that of the FTP.

SFTP is pretty much like FTP as far the connection and usage is concerned. It has just another layer of security to make it more secure while uploading and downloading the file.

Basic server address, username, password and port are still necessary to connect and interact with SFTP server.

fos user bundle security validation

A login authentication would be handled by securitybundle in symfony.

But how about if you need to validate or authenticate username and password from controller?

Here is what you can do

        
        public function authenticatememberAction($user, $password)
        {
           $valid = false;

           $user_manager = $this->get('fos_user.user_manager');
           $factory = $this->get('security.encoder_factory');

           $user = $user_manager->findUserByUsername($user);//get the user first
           if (!empty($user)) {
              $encoder = $factory->getEncoder($user); //then the encoder
              $valid = ($encoder->isPasswordValid($user->getPassword(),$password,$user->getSalt())) ? true : false;
           }

           return new JsonResponse(['valid'=>$valid]);
        }

The above snippet will validate if the provided username password combination is correct or not.

how to deploy symfony application to the production server

Deploy Symfony application to production – setting it live

This is a continuation of deploying symfony application to the server part one

Deploy Symfony application to production part two

4. Installing composer dependencies

Be in your symfony app first

cd /apps/symfony-app

The run the installer here

composer install --no-dev --optimize-autoloader

Under most circumstances, this will run without any problem. If there are any problems, composer will log them for you so follow those and solve those. And this will create a vendor folder in the folder you run composer. Continue reading how to deploy symfony application to the production server

Deploying Symfony on Production Server

Time to ship your symfony app to production? Here are some flight checks. Lets assume your symfony app is in folder symfony-app

1. Don’t put Symfony app in the public accessible folder on your server

If your servers public facing folder is, say, /var/www/html, then don’t put the whole symfony folder there.

Choose another deeper and non-public facing folder. Let say /apps/symfony-app. I will list how you would put the public facing folders later.
For this to happen run this command on your server

mkdir /apps

2. Pushing your code to production server

You can use FTP client like filezilla or cyberduck and put your code in /apps
If you are using git, then you can clone your app like this

cd /apps
git clone https://username@bitbucket.org/username/symfony-app.git symfony-app

test

Run single phpunit test

Well, we all love php unit tests :). There are times we would like to run one/single test from test suite that has failed so that we can fix or look at it thoroughly. PHPUnit has a way to do it.
The problem, when you are your php unit suite as

phpunit -c /testFolder..

All you php tests would run.
The solution for this is:
Let’s assume you have this particular php unit test in one of your test files

public function testPhpIsAwesomeOrNot(){
}

All you have to do is to add the <b>group annotation</b> above the function of your php unit test

/**
 * @group awesome
 */
public function testPhpIsAwesomeOrNot(){}

and run your PHPUnit single test wiht –group annotation

phpunit -c /testfolder --group awesome

The above would run single PHPUnit test from the test suite.

composer install-update killed on vagrant machine

These are also other stuffs going on:
composer update or composer install takes forever and the command line responds as killed

Specially this might happen on ordinary symfony application.Screen Shot 2016-04-10 at 8.16.40 PM

This is mostly, very very likely, related to memory issue.

Solution 1: perform your composer update or install on the host machine if possible.

This might not be possible in some scenarios if there are dependencies that rely on installed packages.

But, if that is not the problem, have on the host and the files would be sync’d anyway.Screen Shot 2016-04-10 at 8.07.07 PM

Solution 2: increase the memory on the provision file you have. I am using puphpet so, for that all you would have to do would be

cd /path/to/puphpet/
vim comfig.yml

then search for memory which by default be 512 and increase it at least to 1024 or better 2048 and that should solve the problem

Tip

To see the how much memory you have on your vagrant machine, ssh into your machine and

vagrant ssh
free -h

the free command would tell you how much memory you have and how is used.

install composer and make it globally accessible

Unless you have been living under rocks, you have heard about composer already. It is a dependency manager and more than that actually. If your PHP app is using a lot of dependencies, then it is time to consult composer.

Here I will put some notes on how to install it and make it available globally so that you can use it from any directory.

First thing first, go and grab the phar file from composer download page

It would be a single phar file and u can use that as it is:

composer.phar install

Of course you would need the composer.json file for the above to work where you would list the dependencies.

But, this would require you to call the phar from where you downloaded and that might not be handy

cd /to/composer/phar/file
sudo mv composer.phar /usr/local/bin/composer

Now, you can call composer from any directory and rock from there
get more @ get composer
That is how you install composer on linux/mac computer and make it globally accessible with in

Who is calling php script browser or cron

Identifying who calls php script

Php script can called from different places or clients. Do you Want to know which client, browser or command line, is calling your php script?
Wanted to handle differently when the script is called from command line
Then use php_sapi_name

Yeah, this sapi thing – Server API is a bit bad boy. You might want to check a manual value comparison before deploying it your server as the sapi return type might be different for different settings say b/n command line script and webserver.

Also having additional check with $_SERVER and $_ENV variables is also a good one for better guarantee. Like some parameters of the $_SERVER would only be set when called from web server like ‘REQUEST_METHOD’

if (!empty($_SERVER['REQUEST_METHOD'])) {
    echo "hey baby web server, calling you from browser X - wssup";
} else {
    echo "umm.. are you cron? manual? who the heck???";
}

Also using the sapi name

$sapi_id = php_sapi_name();
if (stristr($sapi_id, 'cli')) {
    echo "hello command line interface";
}

Since the above would be a bit more conditional it would be advised if used along with existence of like $_SERVER[‘REQEST_METHOD’]

Using the above snippet, you can tell from which the php script is called from and you can say hello to browser or cron.
