I think this is going to be the most important part. I’m really inclined to doubt this is a significant number of people.
Is anyone still using PEAR? PHPUnit just deprecated its PEAR install, and I’d much rather use Composer than PEAR for basically anything.
Edit: Let me rephrase: is anyone who is going to upgrade to PHP7 still using PEAR?
Anyone who’s starting a new project is not using PHP4 constructors. Anyone who’s got a legacy project isn’t going to upgrade to PHP7. I really fail to see what the issue is.
I would suggest removing PHP4 constructors isn’t going to cause problems for most developers.
