Site Crashed U_ILLEGAL_ARGUMENT_ERROR in IntlDateFormatter

[Georgecy]

Thanks guys. I added in PHP.ini the following date.timezone = Europe/Athens and also I cleaned installed Zencart 2.0 tested with PHP 8.11 and PHP 8.3. The problem is the same. When I go to PHP 8.0 the installation works. The logs of ZC 2.0 are listed below. No patch was added in ZenCart 2.0.

Well, you really need to help us more by giving infos about your settings, like what system you are on, what is your actual locale setting in php.ini, lang.english.php or whatever language file you use?
Did you add some code to set timezone in Zen Cart?...
With information I have now, here is what I can see:

Your problem is not related to this thread original post that was a bug in a specific PHP version you do not used.
The problem disappears when using PHP 8.0 or lower because in these cases Zen Cart do not use IntlDateFormatter.
IntlDateFormatter crashes PHP because it is given bad information/settings.
Probably not the solution but in php.ini, you should have

date.timezone = "Europe/Athens" 

rather than

date.timezone = Europe/Athens 

.

When timezone or other necessary setting is not define in the code, IntlDateFormatter uses PHP's one (good or bad) and if PHP's locale/timezone is not set, PHP will try to use system setting with more or less success depending on system.

Thanks a lot for the reply.
I am using Abyss webserver on MacOs 10.12. I can use PHP 7.4, 8.1, 8.2 and 8.3.
In Php.ini I use date.timezone = "Europe/Athens". I tested also Europe/Nicosia and Asia/Nicosia

I do clean installation from the original code zencart-1.5.8a-patched-2024-04-05. I copied the actual folder in htdocs and run the ZC_Install. The database is clean and populated by the demo products. When Installation is finished the ZC-install requests removal of ZC_Install and gives links to both front end and the admin of the store. Both links show a blank page with the log as shown below. If I go to PHP 8 then all works.

I added all the variations of the @setlocale(LC_TIME, ['en_US', 'en_US.UTF-8', 'en-US']); in both Admin/configure and configure without success. I used also @setlocale(LC_TIME, ['el_GR', 'el_GR.utf8', 'el_GR']); I have set on the computer also Greece as region. I am actually in Cyprus.
In the lang.english.php I used also the original US setting and variations as this one $locales = ['el_GR', 'el_GR.utf8', 'en', 'el.Greece'];

It takes me less than 5 minutes to make a new installation either 1.5.8 or 2.0 just give me some recommendations and I will test them and let you know of the results.

Thanks a lot

Thanks a lot for the reply.
I am using Abyss webserver on MacOS 10.12 with a selection of PHP from 7.4-8.1-8.2-8.3.
In PHP.ini I tested date.timezone = "Europe/Athens" and date.timezone = "Europe/Nicosia"

I do clean installation from the zencart-1.5.8a-patched-2024-04-05 using ZC_Install. After installation is complete the links to both Front end and admin show a blank page. i added in both configures the @setlocale(LC_TIME, ['el_GR', 'el_GR.utf8', 'el_GR']); also as Dr Byte gave it also localised.
In lang.English.php I used the default and also the localised $locales = ['el_GR', 'el_GR.utf8', 'en', 'el.Greece'];

In all cases I get a log error as shown below. If I use php 8 then everything works.

I can set up a new installation in a few minutes. I you have any recomendation I can test it and let you know the results.

Thanks a lot.

Try creating a small .php file in the site's root to determine which timezone-identifiers are available to you. See this (https://www.php.net/manual/en/dateti...dentifiers.php) php.net documentation of the way to do this.

Instead of looping through only the first 5 identifiers as in that example, use foreach to list them all. It could easily be that your webhost's PHP installations don't include either Europe/Athens or Europe/Nicosia.

[pilou2]

I just want to add you should check that PHP 'intl' extension is installed, just to be sure. Without it, IntlDateFormatter won't work.
Test lat9 proposed should give us important information.

[Georgecy]

Hi Guys,
timezone-identifiers available from @lat instructions are listed at the end. The important for my case is Asia/Nicosia, Europe/Athens, which are available.( Running Joomla 4 system report, on same PHP, it shows also Europe/Nicosia and UTC as default timezone. Joomla has no problem with the PHP 8.1.1).

The actual timezone declared in php.ini is date.timezone = "Europe/Athens"

The Intl extension is also available.
I entered also in php.ini
[intl]
intl.default_locale = el_GR.UTF-8 which it had no effect on the issue.

Attached also screenshot From info.php


Asia/Aden, Asia/Almaty, Asia/Amman, Asia/Anadyr, Asia/Aqtau, Asia/Aqtobe, Asia/Ashgabat, Asia/Atyrau, Asia/Baghdad, Asia/Bahrain, Asia/Baku, Asia/Bangkok, Asia/Barnaul, Asia/Beirut, Asia/Bishkek, Asia/Brunei, Asia/Chita, Asia/Choibalsan, Asia/Colombo, Asia/Damascus, Asia/Dhaka, Asia/Dili, Asia/Dushanbe, Asia/Famagusta, Asia/Gaza, Asia/Hebron, Asia/Ho_Chi_Minh, Asia/Hong_Kong, Asia/Hovd, Asia/Irkutsk, Asia/Jakarta, Asia/Jayapura, Asia/Jerusalem, Asia/Kabul, Asia/Kamchatka, Asia/Karachi, Asia/Kathmandu, Asia/Khandyga, Asia/Kolkata, Asia/Krasnoyarsk, Asia/Kuala_Lumpur, Asia/Kuching, Asia/Kuwait, Asia/Macau, Asia/Magadan, Asia/Makassar, Asia/Manila, Asia/Muscat, Asia/Nicosia, Asia/Novokuznetsk, etc...., Europe/Amsterdam, Europe/Andorra, Europe/Astrakhan, Europe/Athens, Europe/Belgrade, etc....

Hi Cindy,
The patch @setlocale(LC_TIME, ['en_US', 'en_US.UTF-8', 'en-US']); has been applied to both configure files without success. I initially use GB instead of US but at the end I used the exact statement above. I tried also to changed the Time Zone to Europe/Athens but without success.

When going back to PHP 7.4 or 8.0 the blank pages go away and the the store works as expected.

The logs are the shown below

The part that makes your post the most difficult to troubleshoot is that line 90 of that file doesn't look anything like calling datefmt_create like the error message is suggesting. Here's the file from v158a: https://github.com/zencart/zencart/b...p#L87C1-L91C15

So what exactly is on YOUR line 90, and why is it different from released code?

Even in v2.0.0 it doesn't refer to datefmt_create anywhere close to that line: https://github.com/zencart/zencart/b...ses/zcDate.php
(Although given a few enhancements made to the 2.0 version of that file, it "might" be worth temporarily testing the 2.0 version on your 158a site, as an experiment.)

Definitely the error message you're getting about it saying "No such time zone" means that your PHP environment isn't aware of time zone defaults. So that's a PHP configuration problem. Like others have said, installing the 'intl' extension may help, and I see you've tried that with mixed results.

Your comment about Joomla recognizing it fine doesn't really make any difference here: if Joomla's not using the date functions that Zen Cart is calling then Joomla's not triggering your PHP configuration problem, so it's just hidden by non-use.

Zen Cart doesn't do any trickery. It just uses whatever PHP binary is linked to the vhost that you have configured for the domain you're running the site on. So if your Abyss webserver configuration is pointing this domain to use a certain PHP binary, that's what Zen Cart will run with ... and it will expect that PHP's configuration (installed extensions, ini file contents, etc) to be correct. Zen Cart doesn't do anything fancy with it: it just expects a correctly configured PHP.

[B]The file is exactly the same and on line 90 is IntlDateFormatter::NONE


I tested the 2.0 file and gives the same error on line 92

The 'intl' extension was installed all along.

I refer the issue to the source of the PHP and I am waiting for their comments.
