php spark serve Uncaught Error: Call to undefined function CodeIgniter\CLI\mb_strpos()

I'm new to PHP and trying to open the CodeIgniter 4 welcome page by using localhost (I don't have any server programs like XAMPP since it's a company computer and PHP works fine with its built-in server.)

When I try to run the command: php spark serve on the terminal, it gives an error like this:

Uncaught Error: Call to undefined function CodeIgniter\CLI\mb_strpos() in C:\Users\50290536\Desktop\php-test\system\CLI\CLI.php:776

I enabled the necessary extensions in the php.ini file and the file: php_mbstring.dll is available in the directory php/ext.

I also tried to run the command: php spark to see if spark works fine but in that case, I got the following error:

The framework needs the following extension(s) installed and loaded: curl, intl, mbstring at SYSTEMPATH\Codeigniter.php:224

All these extensions are enabled in the php.ini file and their respective .dll files are available in the directory php/ext.

Details:

PHP version: v8.2

CodeIgniter 4 framework version: v4.2.10

Currently enabled PHP modules after running the command: php -m

In my case the extension_dir directive in php.ini was relative path. If you change it to absolute it should works. For example:

extension_dir = "c:\php\ext"

Alternatively, you can try with these values: "./ext" or ".\ext" or "ext". Make sure you uncomment the directive. (Just delete the semicolon from the beginning)

It is a known bug on some machine/version.

As you said your OS is Windows, you may check if it resolves the problem. I think if the php -m command lists the mbstring extension, then it will fix your original problem, and the CodeIgniter spark will works fine.

Make sure you edit the right php configuration file. You can find the location of your php with the which php or where php commands.

And yes, you can just simply move the php.ini-development to php.ini, it should work.
