Installation fails for PHP 8.2 Topic is solved

[DannyBoy60]

Hello everybody,

sorry to swear in church, but I am trying to install Joomla 4/5 on Windows 11 using IIS, on localhost.
This should work, shouldn't it? But it does not.

Versions:
PHP 8.2.10
IIS 10
Joomla 4.3 and 5.0

0. Preconditions
I set read/write rights on whole joomla subtree. I have a working FastCGI extension to IIS. I have other working php web projects on localhost.

1. Web bowser installation.
Installation through web works fine until "last moments", then a red text appears that the installation did not succeed.
I can find no log files. Except for php_errors.log, which says:
"Function utf8_decode() is deprecated"
Ok, but this should not be lethal, should it?

2. Command window installation
php installation/joomla.php install

2.1 First error message:
Deprecated: Creation of dynamic property Joomla\CMS\Installation\Application\CliInstallationApplication::$clientId is deprecated in C:\inetpub\wwwroot\joomla5\installation\src\Application\CliInstallationApplication.php on line 107

2.2 Then the funny thing happens, that after writing the super user account name, an infinite loop appears.
Deprecated: rtrim(): Passing null to parameter #1 ($string) of type string is deprecated in C:\inetpub\wwwroot\joomla5\libraries\vendor\symfony\console\Helper\QuestionHelper.php on line 427

Attaching a screenshot of this loop.

3. My conclusion is that the installation scripts simply does not work for PHP 8.2.
Is there any workaround?

Unless you have an overriding necessity to use IIS I would use Wampserver on win 11 to create a local web server. IIS hasn't really played well with Joomla over the years.

Well thank you sir!

I downloaded XAMPP (WampServer was kind of strange, did not allow me to deselect parts).

Installed it, worked!

Glad it worked for you, Wampserver is capable of changing php and databases on the fly (+FCGI-php) so you can have many sites on wamp with different php and database simultaneously and can change them individually,very useful for DEV work.
