## Flow PHP
Flow is the most advanced PHP ETL (Extract, Transform, Load) framework.
```php
read(from_parquet(__DIR__ . '/orders_flow.parquet'))
->select('created_at', 'total_price', 'discount')
->withEntry('created_at', ref('created_at')->cast('date')->dateFormat('Y/m'))
->withEntry('revenue', ref('total_price')->minus(ref('discount')))
->select('created_at', 'revenue')
->groupBy('created_at')
->aggregate(sum(ref('revenue')))
->sortBy(ref('created_at')->desc())
->withEntry('daily_revenue', ref('revenue_sum')->round(lit(2))->numberFormat(lit(2)))
->drop('revenue_sum')
->write(to_output(truncate: false))
->withEntry('created_at', ref('created_at')->toDate('Y/m'))
->saveMode(overwrite())
->write(to_parquet(__DIR__ . '/daily_revenue.parquet'))
->run();
```
```console
$ php daily_revenue.php
