PHP 7 compatibility

Hi @danbrady,

Actually when developing Booster, we use test server with PHP v7.1.9, so there should be no real issues. However I will check it with compatibility checker plugin. What plugin did you use, is it this one – https://www.ads-software.com/plugins/php-compatibility-checker/ ?

Best regards,
Tom

Yes, that’s the plugin I used. I think it actually just gave an ‘unknown’, because the process cancelled checking the booster plugin becuase of its size

Good to know you are already using PHP 7.1.9 for testing

Thanks

Hi @danbrady,

Thanks for the info. I’ve just run compatibility check for PHP v7.2, and there were some issues, however all of them are coming from an external library we are using – TCPDF. It is loaded only if you are using Booster’s “PDF Invoicing” module. Other than that there were no issues detected in plugin itself. We are going to update TCPDF to newest version soon, so hopefully plugin will fully pass PHP v7.2 check then.

Best regards,
Tom

Hi Tom, thanks for checking and for your detailed response.

We don’t use the PDF invoicing module, though we do use TCPDF on other projects, but it’s good that you’re upgrading it soon

PHP 7.1 is our goal at the moment (as I suspect too many other plugins won’t work with 7.2), but 7.2 will be a priority soon.

Hi danbrandy and thank you for this super plugin!

Same topic, my PHP checker is from my hosting SiteGround.
They reports these errors for upgrade to PHP 7.1:

What do you think? May I ignore them?

Hi @telengo,

Thanks.

All this comes from external libraries we use, and both libraries are loaded/used only in Booster’s “PDF Invoicing” module. We have latest versions of both libraries included. Our development server, which we use for Booster development, has PHP v7.1 installed and there are no issues (nothing in log or on frontend). So to sum up – there should be no issues transferring your site to PHP v7.1.

Hope that helps.

P.S. If you like Booster, please leave us a rating.

Best regards,
Tom
