We should check if $content is an array before checking the isset. Not sure that PHP will not complain about this.
In this case is not strictly required, but I suggest always to use the === strict comparison.

isset wont generate a notice in that case if the index does not exist. Also, it's applicable not only to arrays, the function checks that the variable is set. So, not sure we should use is_array here, which may be more expensive and redundant.
As for the strict comparison, absolutely makes sense, thank you.

Comment on code readability:
Since you use getFileContent twice (line 81 and 95), why not to put the result in a variable?

Agree, the mentioned approach improves the readability, thanks.

Please use type hints in method signatures both for parameters and return types. Looks like only return type applies to this specific case

Sure, I always go this way for a new classes. I had doubts about methods within a scope of existing classes with no type hints/strict types.

@rogyar , you are right if it was public because of possible plugins on it not matching the signature, but with a private method is definitely safe.

@ishakhsuvarov absolutely. I'm going to do that as well as adjust packingslips/credit memo generation. Just wanted to make sure that we go the right way. Thank you. |

LGTM, just check tests. |

Finally, handled the failing tests :) |

Hi @phoenix128, thank you for the review. |

Hi @rogyar. Thank you for your contribution. Please, consider to port this solution to 2.3 release line. |
Description
Upon invoice/packingslip/credit memo printing the system generates a PDF file directly in the
vardirectory. I see no reason for keeping these files since they are not accessible publicly via web (sharing purpose). There's no "reuse" purpose as well since on every print action a new file with a new filename is being generated.This PR provides a logic for removing a PDF file once it's generated.
Currently, it's implemented only within a scope of the invoice printing. Once we agree on the solution, I will adjust other places with PDF generation.
Fixed Issues (if relevant)
