Can any one tell me how to edit this part of the FF mimetypes.rdf to make it open php files from local computer?



<RDFescription RDF:about="urn:mimetype:text/x-php"
NC:fileExtensions="php"
NC:description=""
NC:value="text/x-php"
NC:editable="true">
<NC:handlerProp RDF:resource="urn:mimetype:handler:text/x-php"/>
</RDFescription>

this is in reference to this thread:
