InvalidArgumentException: The locale option does not look like a valid locale

[madeincosmos]

This error is only triggered when intl fails to load:

InvalidArgumentException: The locale option does not look like a valid locale: LC_CTYPE=en_US.UTF-8;LC_NUMERIC=C;LC_TIME=C;LC_COLLATE=C;LC_MONETARY=C;LC_MESSAGES=C;LC_PAPER=C;LC_NAME=C;LC_ADDRESS=C;LC_TELEPHONE=C;LC_MEASUREMENT=C;LC_IDENTIFICATION=C. For more option install the intl extension. 

The regex here expects locale in format such as en_US.UTF-8 instead of what's given:

https://github.com/rlanvin/php-rrule/blob/master/src/RRule.php#L2084

According to setlocale specs, all these extra parameters will normally be returned for setLocale(LC_ALL, 0), which is called here:

https://github.com/rlanvin/php-rrule/blob/master/src/RRule.php#L2193

To only get en_US.UTF-8 we'll want to use LC_CTYPE instead:

https://www.php.net/manual/en/function.setlocale.php#106811

Applying this change on my test site solved the problem for me.

Hi @madeincosmos @rlanvin

Have same issue with:

The locale option does not look like a valid locale: C.UTF-8. For more option install the intl extension.

In order to fix this is mandatory to install intl?

Hi @FROXZ, no it's not - I believe the reason you're seeing this error is that "C" as a locale is simply not supported (since it doesn't correspond to any language file).

Hi @rlanvin thank you for reply.

Seems this works without chaning php/server locale:

$rrule->humanReadable([
	'use_intl' => false,
	'locale' => 'en',
]);

P.S. Thank you for amazing library.
