Subject:   Issue with MediaWiki Installation: IntlException and Locale Problems in Apache

Hi group,

I'm trying to install MediaWiki on FreeBSD with Apache and PHP 8.1 via 
mod_php, but I keep running into an issue related to the `Intl` 
extension and locale settings. During the MediaWiki installation 
process, I get the following error:

```
IntlException: Constructor failed
```

There are no errors in the Apache log, and I have doublechecked that the 
`Intl` extension is enabled and working in CLI PHP. When I run the same 
code via Apache, it throws an exception.

I created a minimal PHP test case to see if I could reproduce the error 
outside of MediaWiki. Here's the test script:

```
<?php

// Set the locale to test
$locale = 'en_US.UTF-8';

// Check if Intl extension is loaded
if (!extension_loaded('intl')) {
     die("Intl extension is not loaded!\n");
}

// Display the current locale settings
echo "Current locale: " . setlocale(LC_ALL, 0) . "\n";

// Test the Intl NumberFormatter
try {
     $formatter = new NumberFormatter($locale, NumberFormatter::DECIMAL);
     echo "Number formatting test: " . $formatter->format(12345.67) . "\n";
} catch (Exception $e) {
     echo "IntlException: " . $e->getMessage() . "\n";
}
?>

```

Results:

- Command Line PHP:

   ```
   Current locale: C/C.UTF-8/C/C/C/C
   Number formatting test: 12,345.67
   ```

- Apache (via browser):

   ```
   Current locale: C/C.UTF-8/C/C/C/C
   IntlException: Constructor failed
   ```

So the same script works on the same jail on cli but not in Apache with 
mod_php.

What I've Tried

- I have set `LANG` and `LC_ALL` to `en_US.UTF-8` in both the Apache 
environment and PHP’s `php.ini`.
- I verified that the `Intl` extension is loaded in both CLI and Apache 
environments.
- `phpinfo()` reports the correct locale in Apache (`en_US.UTF-8`), but 
the error persists.

I'm really running out of ideas here, I run MediaWiki for years and 
while it's a new jail to upgrade my env, this is not something I've seen 
before.

Note that I tried the same with PHP 8.2, same error.

Any suggestions on how to resolve this would be greatly appreciated.

thanks & regards

Adrian
