Steps To Reproduce:

php artisan serve for any laravel project. Would appreciate any guidance on providing further information to pinpoint the issue.
It is worth noting that I'm using the PHP_CLI_SERVER_WORKERS=6 environment variable. The problem seems to disappear without it.

Found the commit e7ac9b1

Seems that the culprit is getDateFromLine(). Can you dump $line and $matches? It may be a problem with how WSL returns the server date. Which Ubuntu version, btw?

[TheRealMkadmi]

I'll report back as soon as it happens again
I'm on Ubuntu 22.04

Hi there,

Thanks for reporting but it looks like this is a question which can be asked on a support channel. Please only use this issue tracker for reporting bugs with the library itself. If you have a question on how to use functionality provided by this repo you can try one of the following channels:

However, this issue will not be locked and everyone is still free to discuss solutions to your problem!

Thanks.

This is not a support question or a question on how to use the framework.
This is clearly an issue within the a core part of the framework that could be addressed with a patch. Hereby needs an issue on the bug tracker.

@DarkGhostHunter

Here's what dd($time, $format, $lastErrors); gives at line Creator.php:675:

^ "488"
^ "D M d H:i:s Y"
^ array:4 [
  "warning_count" => 0
  "warnings" => []
  "error_count" => 2
  "errors" => array:2 [
    0 => "A textual day could not be found"
    3 => "Not enough data available to satisfy format"
  ]
]

ServeCommand.php:239
$line evaluates to: [516] [Sat Sep 17 20:09:40 2022] 127.0.0.1:55020 Accepted
Seems like it's trying to parse the [516] as a date instead of the content of the second bracket

Here's the output of the PHP built in web server on my machine:

[596] [Sat Sep 17 20:20:54 2022] 127.0.0.1:55530 Closing
[595] [Sat Sep 17 20:20:54 2022] 127.0.0.1:55531 Accepted

the preg_match('/^\[([^\]]+)\]/', $line, $matches); outputs just [596] in $matches . Seems that's our problem.

@driesvints can we reopen this?

Seems like a PR was sent in so let's see how that goes.
