Doctor: allow_url_fopen and curl_multi_exec()

[joho1968]

Describe the issue

Under Doctor > PHP, you may want to check for the PHP setting allow_url_fopen, and show a warning if it's disabled.

Also under Doctor > PHP, you may want to check if curl_multi_exec() exists. We lock down our environments quite a bit by disabling a number of functions. Currently it throws and exception if I go to System > Plugins. The exception is

Exception Error: "Call to undefined function Symfony\Component\HttpClient\Response\curl_multi_exec()" at CurlResponse.php line 284

You may also want to change the word Doctor to Health or Health check.

The documentation / installation instructions should probably mention these two.

Thanks for sharing.
Can you share where allow_url_fopen is used?

Sorry, my bad. I had that in the note text, but apparently did not copy it 🙄

If allow_url_fopen is disabled, this appears in the log:

[2024-04-04 14:55:48] [php] WARNING: Warning: file_get_contents(https://api.github.com/repos/kimai/kimai/releases): Failed to open stream: no suitable wrapper could be found {"exception":"[object] (ErrorException(code: 0): Warning: file_get_contents(https://api.github.com/repos/kimai/kimai/releases): Failed to open stream: no suitable wrapper could be found at /kimai/src/Utils/ReleaseVersion.php:43)"} []

Okay, so allow_url_fopen is used to find the latest Kimai version and the curl method to fetch the plugins.

Gracias 😄

Why not simply write a function that checks if curl_multi_exec is available, if so use that, if not, check if allow_url_fopen is true/on, and if so, use that; and if none of them are available, display a warning on the "Health" (Doctor) screen ... 🤔

I cannot write custom code for every possible environment combination.
It is documented that curl is required. You decided to disable it anyway....

I am catching Throwables / RuntimeExceptions in the next release, so you will see the default error once every 24 hours:

Should be enough. Thanks for the report!
