just adding tests for php74

maybe it's time to remove support for unsupported PHP versions. But not sure about this.

[kokspflanze]

so we should only support php72- php74 right?
for me its no problem to drop the support for the old php versions

[svycka]

I still use PHP 7.1 on some old projects but maybe its time to update. And if no one is against this then let's do this.

I'm not using this anymore so for me no issue either...

looking at the packages statistics i would say its not a problem. just tag it as 0.5

[svycka]

@kokspflanze can you resolve conflicts and rebase? Or I will do just don't know when maybe next week

[kokspflanze]

@svycka i will do it today in the evening=)

PHP fixer fails. We either need to get a version that run on 74 or move the check to php73 (in travis config)

@basz yep, have to update my local php version to fix it^^
