The modern concept of ‘web services’ has always existed in one form or another. Originally the protocols were binary and incredibly complex to integrate, but times have changed a lot. However, there are still large swathes of service providers who provide web-based APIs, but only support primitive versions of these- relying on ‘file drops’ and simple callbacks. Worse still, these providers are particularly resistant to changing their ways. This can be a serious bar of entry for more modern development companies who are used to a SOAP/REST based system, stopping them climb the supplier chain.
This short example shows how you can use PHP to integrate with a supplier who insists on using a file drop mechanism – in this case, to get your date-stampped CSV files, prefixed “file-” wrapped up in ZIP file using the format user-DMY, on an FTP site of their choice!
