False positive: Call to function file_get_contents() on a separate line has no effect.

Bug report

file_get_contents can be used to product a side-effect. It does not have to care about the returned content. However, even such usages should probably check for error. I'm also not sure if it's a good idea to use file_get_contents like this in the first place. So perhaps the message could simply be reworded.

Expected output

It should not be claimed that it doesn't have any effect.

Similar issues have been fixed recently in phpstan/phpstan-src#698

I guess you can just edit the same files and turn sideEffects on for file_get_contents

If it's your intended usage, just ignore the line.
