How can I check easily an old app if it has compatibility to PHP 7?
My Phpstorm version is 2018.3
Thank you !
*EDIT: I already used "Run Inspection By Name" / "Deprecated for PHP General"/ with the project setting PHP version 7.3.
Phpstorm showed many deprecated things. The question is now: It is just a hint or do all these things have to be replaced through others or could they stay? Are they just deprecated and also can still be used in PHP 7.3?
