sc9 supports what PHP version?

[capecode]

In one of my apps, everything worked fine under SC9 development environment. But when I deployed it under PHP 7.2.x, I keep getting error “cannot use string offset as an array”

In another app, I keep getting “Array to String Conversion Error” under PHP 7.2.x but works fine under PHP 7.0.x and SC9 development environment.

Any suggestions?

I guess I have to stick with PHP 7.0 then.
