Any documentation with common examples?

Hi ! Thanks for the library but It is a madness :/

Any documentation with common examples?

I am trying to get the Symbol of a ERC-20 like this:

$contract->at($contractAddress)->getData('symbol');

The return: 95d89b41 (the result would be Uni 2.6)

I am trying to convert from Utils::toString, utf_encode, utf_decode, pack.... nothing works

Thanks.

This code solved it:

$contract->at($contractAddress)->call('symbol', function ($err, $result) {
  if ($err !== null) { return; } 
  echo 'The symbol: ' .  $result[0];
});

Any way to getPastEvents with this library?

Thanks
