Example of loading ABI or resolve constructor aren't able to add functions, and events #314

Please post an example of loading $abi or resolve constructor problem.

I can load $abi but $contract->constructor functions, and events doesn't exist so I got the error below when I try to do estimateGas->('functionName', [params]).

exception: "InvalidArgumentException"
file: "/api/vendor/web3p/web3.php/src/Contract.php"
line: 719
message: "Please make sure the method exists."

code

$abi = file_get_contents(base_path('abi/contracts/SupportTicketV0.sol/SupportTicketV0.json'));
$contract = new Contract('http://localhost:8545', $abi);

$contract->at('0x9fE46736679d2D9a65F0992F2272dE9f3c7fa6e0')
            ->estimateGas(
                'mint',
                [
                    '0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266',
                ],
                [
                    $fromWalletAddress,
                    $toWalletAddress,
                    $quantity,
                    $tokenURIs,
                ],

Also I checked getFunctions and returned empty array like return $contract->getFunctions();.

I guess $abi must be formatted before loading but I'm not sure how format it. $abi is just generated from yarn hardhat compile.

Thank you.
