没有用过web3.php。但是你可以把下面的tokenAddress换成你说的dom。fromAddress为转出地址（该实例中为钱包地址）receiver为转入地址

```
const sendERC20Transaction = async (receiver, amount) => {
    var Tx     = require('ethereumjs-tx')
    const Web3 = require('web3')
    const web3 = new Web3('https://mainnet.infura.io/v3/your-project-id')
    web3.eth.accounts.wallet.add('privateKey of fromwallet');
    var contractAbi =[];
    var tokenAddress = '0xdAC17F958D2ee523a2206206994597C13D831ec7'//Tether token(USDT)
    var fromAddress = '0x3df...'
    var tokenInst = new web3.eth.Contract(contractAbi,tokenAddress);
    tokenInst.methods.transfer(receiver, amounts).send({from: fromAddress, gas: 100000},function (error, result){ //get callback from function which is your transaction key
        if(!error){
            console.log(result);
            handleSuccessTrue();
        } else{
            console.log(error);
            web3.eth.getBalance(fromAddress, (err,bal) => { alert('Your account has ' + web3.utils.fromWei(bal, 'ether') + ', Insufficient funds for gas * price + value on your wallet')});
            handleSuccessFalse();
        }
    });
//Finally, you can check if usdt tranaction success through this code.
tokenInst.methods.balanceOf(receiver).call().then(console.log)
.catch(console.error);
```
