PHP 7.12 "A non-numeric value encountered"

[exodus4d]

[23-Feb-2017 18:42:16 UTC] A non-numeric value encountered 
[23-Feb-2017 18:42:16 UTC] [I:/webpages/pathfinder/app/lib/base.php:2159] Base->error() 
[23-Feb-2017 18:42:16 UTC] [I:/webpages/pathfinder/app/lib/base.php:1122] Base->{closure}()

And here is how to fix it (int) cast is required: https://github.com/bcosca/fatfree/blob/master/lib/base.php#L1119

header('Expires: '.gmdate('r',$time+(int)$secs));

And here is why this happens: dompdf/dompdf#1272

that means you are calling expire with an empty string instead of a number?

[exodus4d]

I don´t call the expire() function from anywhere in my code :)

I have some Ajax routes like this:

GET|POST /api/@controller/@action               [ajax]  =   Controller\Api\@controller->@action, , 512

I guess the "empty string" before the throttling of 512 is responsible for that. Ill try to set it it explicit to 0 when I´m back home

[exodus4d]

Yeah setting it to 0 fixed it as well.
You can decide whether you want to change/fix this or not.
Feel free to close this issue, if you want.

[KOTRET]

well, although its more of a configuration-issue, this should be fixed with a cast ($secs = (int)$secs;) to make the framework more robust.

Edit: to clearify: a blank " " string is passed, not an empty string
