Iam familiar with ROR development. But recently started working in php zend framework. Is their a way to see the development logs live in the terminal(in linux) same as ROR as.

RAILS_ENV=development

rails s

But In Zend the its terminal command

php -S 0.0.0.0:8080 public public/index

produce logs in production environment.How to get them development like to monitor the code more specifically.
In documentation it has it like:

if ($_SERVER['APPLICATION_ENV'] == 'development') { error_reporting(E_ALL); ini_set("display_errors", 1); }

But show error message in terminal as:

PHP Notice: Undefined index: APPLICATION_ENV in /var/www/html/skeleton/public/index.php on line 7

that's bit wearied please suggest a way out thanks.

which version of zend framework you are using? – Gautam Rai
Difficult to to tell what you're asking here, but at a guess you're maybe looking for this -> stackoverflow.com/questions/18098006/… – Crisp
zend version 2.4.13 – user8112782
What you see in the terminal window are the web server logs (which will include errors). Zend Framework does not do any additional logging by default. – Tim Fountain

The problem

The documentation assumes that you’re using Apache:

Optionally, when using Apache, you can use the APPLICATION_ENV setting in your VirtualHost to let PHP output all its errors to the browser. This can be useful during the development of your application.

Source: the manual.

First solution: define APPLICATION_ENV

As discussed in another question, you should be able to run your development server with defined APPLICATION_ENV using the following command:

APPLICATION_ENV=development php -S 0.0.0.0:8080 public public/index

Second solution: use Apache

You may simply setup an Apache VirtualHost as said in the manual. Put the following in your VirtualHost config:

<VirtualHost *:80>
    ServerName zf2-tutorial.localhost
    DocumentRoot /path/to/zf2-tutorial/public
    SetEnv APPLICATION_ENV "development"
    <Directory /path/to/zf2-tutorial/public>
        DirectoryIndex index.php
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>

And update your hosts:

127.0.0.1 zf2-tutorial.localhost localhost

Refer to the manual in case of problems.

Third solution: use zf-development-mode

I won’t guide you through installation of this package (here are some instructions), but I’ll present two solutions for checking (in your code) whether development mode is enabled.

First method: check if config/development.config.php exists

After enabling development mode, contents of config/development.config.php.dist should be copied to config/development.config.php. In your code, use the following to check if you’re in development mode:

if (file_exists('config/development.config.php')) {
    // in default skeleton application. You may have to play with
    // __DIR__ if you’ve modified your public/index.php
}

Second method: inject application config

Let’s assume that you want to check if development mode is enabled in a controller/service or other thing that can be created by a factory implementing zend-servicemanager’s FactoryInterface. Below I present example application config, factory and service:

config/development.config.php.dist

<?php

return [
    'development' => true
];

Application\Service\Factory\ExampleServiceFactory

public function __invoke(ContainerInterface $container, $requestedName, array $options = null)
{
    return new ExampleService($container->get('Config'));
}

Application\Service\ExampleService

<?php

// imports, namespace…

class ExampleService
{
    protected $dev;

    public function __construct(array $config)
    {
        $this->dev = isset($config['development']) && $config['development'] === true;
    }

    public function doSomething()
    {
        if ($this->dev) {
            // …
        }
    }
}
