Note: going down from PHP 7.4 to min 7.2 is OK. But in practice, I think that the test code has has PHP 7.3 and/or 7.4 parameter and return type declarations etc added to it. So the test code might not actually run with PHP 7.2.

I don't want to go down, i just took the composer.json from the edge branch and modified it.

I am surprised. master gets merged into edge every few weeks, so composer.json should get updated in edge. If that is not happening, then I might make a PR to the edge branch to apply the PHP 7.4 change.

@ishank011 @labkode this should be merged to master to prevent collisions with the vendor folders from php deps and golang deps.
