Came here due to Youtube's algorithm, stayed for the content. Even for stuff I thought I had a good grasp on, there are always valuable gems inside every video that make me go "What? You can do this?"! I can't thank you enough for the good work and awesome way of presenting the material. Keep up the excellent work Gio! Please don't stop. We need more! Thanks again!

Great lesson again. I like that you teach as much about the php language, as oop design concepts and how to setup a working dev environment and use populair packages. A great start for anyone that wants to step into modern code practices.
Thanks, Gio. Learning a lot from you.

best php tutorial I've seen ever.

Awesome, watching your course i improved not only my php skills specifically, but coding overall. I see a lot of improvements in my JS code after watching your course to this point. Thank you 👍👍👍

Wow. This is all new to me. I followed and practiced as well. It's great to see how some of these things work. Thanks Gio. I'm fired up to move on.

Bro, I need help really bad. (1) You installed MailHog using docker and some of us are not using docker (2) at timestamp 8:35, your video is not showing the use classes and when tried to import the class, my script imports classes which i assume to be correct (3) The is view for "users/register" which is not mentioned in the video. To resolve (1) I setup my email account in my own shared vps host but do not where to include the user password.

Yeah ok but how to implement this mailer to a HTML <form> website? You start here 2:46 with a PHP document. Where is this from and what to do with this PHP document?

[stephen.cabreros]

w0w we simply swap mailer to our custom mailer as an example of implementing an interface or implementation, splendid

[devanii]

Very nice! Do you leave the dsn in production empty? Or to null

[expresscoding]

Hello sir, I've a question, you removed this line of code: $mailer = new Mailer($transport); from UserController while refactoring at near the end of the lesson, but it still works, how is that possible, please explain it sir.

[DigitaSkills]

I am a little lost how can we access the config variable without using this keyword and since when is this function is available

[liym-ntairaylangdji]

composer : The term 'composer' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path
is correct and try again. that is what happen when trying composer composer require symfony/mailer 😟😟

[AlexDolon]

Hey Gio, I try to send emails using mailhog but I get this error "Uncaught Connection could not be established with host "mailhog:1025": stream_socket_client(): php_network_getaddresses: getaddrinfo for mailhog failed: Temporary failure in name resolution in Please what could be the solution?

[lairotuT-Tutorial]

This lesson will keep me busy for a while :-) Great great stuff Gio!

First of possibly many questions:
in the Symfony package @ I can see inside the constructor:
$this->headers = $headers ? clone $headers : new Headers();

You mentioned cloning in some lessons before but I am not really understanding why in case of an Email we should clone this object instead of just passing it through?
$this->headers = $headers ? $headers : new Headers();

At least I would (if really needed, clone the headers object one layer above and in addition would get rid of the nullable Headers... that makes no sense imo as we create the object if it is not existing ergo: We will obviously always need it.
public function __construct(
private Headers $headers,
private ?AbstractPart $body = null,
) {}

Would you agree?
