FM2JSON is a PHP script that outputs a JSON string of the query results from the XML results obtained from a Filemaker Pro Server (Advanced) v12+ Custom Web Publishing (CWP).

Background: Versions of FMP Server allowed for XSLT processing via the Web Publishing Engine in FileMaker Server Advanced, but Filemaker has removed that function as of v.12. I have a few applications that were using Six Fried Rice's fm2json XSLT Filemaker to JSON Converter, but didn't want to rewrite my apps to use Filemaker's XML results.

You just need to edit the HOST_PORT variable definition to where your Filemaker Server is hosting CWP.

Follow the parameters used for XML querying in the Filemaker Pro 12 Custom Web Publishing Manual

The JSON object returned has the basic structure as below. Note that this is using Filemaker XML Grammar fmresultset. See Six Fried Rice's fm2json for more information about the JSON object generated. It's generally the same, with the exception of the error code.
