restore PHP 5.3 compatibility

[remicollet]

As, from composer.json, 5.3 is still supported...

Duh. Thanks!

Does Fedora actually still need 5.3 compatibility?
Otherwise I'll consider migrating to 7.3...

[remicollet]

Fedora only provides PHP 7.2+ ;)

BTW, I still maintain this package in EPEL, which is important for us, as used to build our autoloaders (we don't use composer), and EPEL-6 still have 5.3 by default (EPEL-7 have 5.4...)

EPEL-6 will be EOL in Nov 2020, and EPEL-7 in June 2024 (EPEL-8 should exists in a few weeks / months)

But feel free to raise minimal PHP dependency if it make sense for you
(I a critical issue really hurt us, I will still be able to backport the needed fix)

Perhaps you can keep this commit in master, without releasing a new version, to see if some other users come ti cry. Could give you a good idea of how this package is used.

Good idea.

I guess most people these days use composer's autoloader dump or box to generate phars but I somehow like my approach better ;)
