Hey fellow developers!

Let me start by saying I am pretty new to all of this. Hopefully I am posting in the right board. I am new to the SOAP api, and development on the SFDC platform all together.

I am trying to code (with PHP) a script that clears out certain date fields in a custom SFDC object. The problem is, I don't know what I should be passing to this field to clear it out. I have tried passing "null", "0", "false", "" (blank), and I keep getting the error:

Fatal error: Uncaught SoapFault exception: [soapenv:Client] '' is not a valid value for the type xsd:date in /path/to/soapclient/SforceBaseClient.php:509

 I can't imagine there isn't a way to clear out this field via the API. The field is not marked as required in SFDC. Does anyone have any ideas for me to try?

Thanks in advance!!
