php artisan serve can't bind to any port

[vitorsemeano]

• Laravel Version: 8.0.1
• PHP Version: 7.4.10
• OS: Windows 10
• Database Driver & Version: no database needed

Description:

After upgrading to laravel 8, and running the command php artisan serve, it responds with an error recursively, like so:

This behavior does not happen if i change php version to 7.4.5 or switch to laravel 7.x.

Steps To Reproduce:

1. have a laravel project started up with version 8.x
2. make sure you have the most recent stable php version installed (at time of writing 7.4.10)
3. run php artisan serve
4. see that the command can't bind itself to any port

As additional note, i debugged the generated command (running php artisan serve), and copy paste it directly in the command line and it worked, without returning any error.

If you need any more info, just ask.

Thanks

We don't use windows ourselves so feel free to send in a PR which fixes this on Windows.

Can't reproduce this. Might be something on your machine interfering.

Hi, thanks for your feedback.

I managed to resolve this issue. Not quite sure what as the cause, but it was related with something not right in php.ini.

So what i did was use the standard php.ini-development (that comes with a pre built php), and add whats missing in the file and should work. In any doubt try only renaming php.ini-development to php.ini without modifying its contents.

The one line I needed to change in my php.ini to fix this problem was
variables_order = "EGPCS"
to
variables_order = "GPCS"

Something to do with the Env variable. No ideia how this affects the core functionality of php built in server to this degree.

It's in the 8^ laravel upgrade. Because the server if one run it directly works fine:

php -S 127.0.0.1:8000  -t public/ server.php

and in Laravel 7 artisan serve works without problems (windows 10, php 7.4.6).

For me, it was silly mistake. I have installed php in new machine but php.ini was missing. So, I have created php.ini file from php.ini-production file and then php artisan serve command worked fine as expected.

php.ini was missing .Check whether your composer has installed.

After upgrading php7 to php8 for XAMPP,I receive this error.re-creating php.ini from php.ini-production works for me.

Hi guys, I created a merge request #40819 to fix the issue. Could you try it out to see if it's working?

[omniaSayed]

The one line I needed to change in my php.ini to fix this problem was variables_order = "EGPCS" to variables_order = "GPCS"

Thanks！This is a very good

[dhurbamis]

Yes, it was php.ini

change below
variables_order = "EGPCS"
to
variables_order = "GPCS"

[MiN6JI]

variables_order = "EGPCS"

to

variables_order = "GPCS" 

If you are using laravel herd and facing same issue and can't find the php.ini just right click the herd icon from the taskbar and open the configuration files you will see all your php version folders, click onto the one of the folder as per your configuration of php and search for php.ini and make the above changes.

In case anyone using PVM on windows comes here looking: I installed a new version of PHP using PVM, but it didn't come with a php.ini file. That was causing the issue. To fix it, I just had to add a php.ini file.

[scrucher]

if you're using windows open your powershell and type
php --ini
that comand will provide the path to your php.ini file, then go to your laravel app click on vendor => laravel => sail => runtime then choose which php version instaed on your machine copy the php.ini file and post it to the initial php.ini file that will be able to solve the issue on windows OS

For windows PowerShell,

This worked for me in 2024 with php version 8.3.11
