Big red warning message into PrestaShop when not using the right PHP version

[matks]

Is your feature request related to a problem?

I just saw 2 bug reports about very, very weird behaviors ... the people reporting them said "I upgraded to 1.7.6.7 and now this page does [weird behavior]". Obviously I could not reproduce the bugs.

Finally the main reason behind this very weird bug was they were not using the right PHP version.

Describe the solution you'd like

In order not to waste users time and PrestaShop team time, I suggest that, on Back Office pages, when we detect that user PHP version is not supported, we display a BIG RED MESSAGE telling this to user.

This will help users troubleshoot issues faster 😄

The message would say You are using a PHP version that is not supported and this can affect your store. Please check PHP requirements and change for the suitable PHP version. in Admin.Notifications.Warning. - edited by @LouiseBonnard on September 11th, following @Julievrz's wording suggestion.

It should be displayed only on the dashboard. Here is the design mockup:

Here are the specifications: PrestaShop/prestashop-specs#173

Ping @PrestaShop/prestashop-product-team
Here's a great improvement suggested by @matks.
Do you think it could be implemented ?

Thanks!

Nice idea, thanks @matks! I suggest displaying it every time a user goes to his store, so at each connection, on the first page displayed. A popup like a modal might be more effective since it requires an action from the user to either Upgrade (redirecting to https://www.php.net/downloads?) or Close the window. @TristanLDD, @prestascott, what do you recommend?

For the warning message, I propose You are using a PHP version that is no longer supported and this can affect your store. Please upgrade to PHP %s version. in Admin.Notifications.Warning. And what about What do you think, @matks and @Julievrz?

You're considering they are using only and outdated version. What about recent versions of PHP that are not already supported?

[LouiseBonnard]

We could think about a wording that would apply to both cases then.

What do you think of this sentence: " You are using a PHP version that is not supported and this can affect your store. Please check PHP requirements and change for the suitable PHP version."
