Let's migrate a Symfony 2.8 LTS application to Symfony 3 LTS

Handle deprecations

First of all, ensure you don't have any deprecated!

The Symfony documentation explains it well, but let's sum up:

• install the phpunit bridge ($ composer require --dev symfony/phpunit-bridge)
• also check all your pages using web profiler and be ensure there is no deprecation error handled
• found errors and need help about how to fix it ? I did a sort of guide.

# Hello, and welcome to makefile basics.
#
# You will learn why `make` is so great, and why, despite its "weird" syntax,
# it is actually a highly expressive, efficient, and powerful way to build
# programs.
#
# Once you're done here, go to
# http://www.gnu.org/software/make/manual/make.html
# to learn SOOOO much more.

In order to generate and log a warning message about a deprecated Symfony feature, use the trigger_error() function as follows:

trigger_error('The enctype method of the form helper was removed. You should use the new method start instead.', E_USER_DEPRECATED);

Please, be as explicit as possible in the deprecation message and always explain the alternative way to use that feature, property, method or class.

{% import 'macro.html.twig' as macro %}

{{ attribute(macro, 'type_1', 'Foobar') }} {# <p>Type One Foobar</p> #}
{{ attribute(macro, 'type_2', 'Barfoo') }} {# <p>Type Two Barfoo</p> #}

Screencapture and animated gifs

I say "animated gif" but in reality I think it's irresponsible to be serving "real" GIF files to people now. You should be serving gfy's, gifv's, webm, mp4s, whatever. They're a fraction of the filesize making it easier for you to deliver high fidelity, full color animation very quickly, especially on bad mobile connections. (But I suppose if you're just doing this for small audiences (like bug reporting), then LICEcap is a good solution).

Capturing (Easy)

1. Launch quicktime player
2. do Screen recording
