Mime part numbering

[bill]

IMAP_FETCHBODY requires the "part number" to fetch.
Can anyone point me at how the part numbers are derrived.

for example, here is the formatted parts array from a message:
Parts:
array(2) {
[0]=object(stdClas s)(12) {
["type"]=int(0)
["encoding"]=int(0)
["ifsubtype"]=int(1)
["subtype"]=string(5) "PLAIN"
["ifdescript ion"]=int(0)
["ifid"]=int(0)
["lines"]=int(1)
["bytes"]=int(38)
["ifdisposit ion"]=int(0)
["ifdparamet ers"]=int(0)
["ifparamete rs"]=int(1)
["parameters "]=array(2) {
[0]=object(stdClas s)(2) {
["attribute"]=string(7) "CHARSET"
["value"]=string(10) "ISO-8859-1" }
[1]=object(stdClas s)(2) {
["attribute"]=string(6) "FORMAT"
["value"]=string(6) "flowed" } } }
[1]=object(stdClas s)(15) {
["type"]=int(2)
["encoding"]=int(0)
["ifsubtype"]=int(1)
["subtype"]=string(6) "RFC822"
["ifdescript ion"]=int(0)
["ifid"]=int(0)
["lines"]=int(34)
["bytes"]=int(1609)
["ifdisposit ion"]=int(1)
["dispositio n"]=string(6) "INLINE"
["ifdparamet ers"]=int(1)
["dparameter s"]=array(1) {
[0]=object(stdClas s)(2) {
["attribute"]=string(8) "FILENAME"
["value"]=string(21) "TEST OF HTML MAIL.eml" } }
["ifparamete rs"]=int(1)
["parameters "]=array(1) {
[0]=object(stdClas s)(2) {
["attribute"]=string(4) "NAME"
["value"]=string(21) "TEST OF HTML MAIL.eml" } }
["parts"]=array(1) {
[0]=object(stdClas s)(12) {
["type"]=int(0)
["encoding"]=int(0)
["ifsubtype"]=int(1)
["subtype"]=string(5) "PLAIN"
["ifdescript ion"]=int(0)
["ifid"]=int(0)
["lines"]=int(10)
["bytes"]=int(251)
["ifdisposit ion"]=int(0)
["ifdparamet ers"]=int(0)
["ifparamete rs"]=int(1)
["parameters "]=array(2) {
[0]== object(stdClass )(2) {
["attribute"]= string(7) "CHARSET"
["value"]= string(10) "ISO-8859-1" }
[1]= object(stdClass )(2) {
["attribute"]= string(6) "FORMAT"
["value"]= string(6) "flowed" } } } } } } ["value"]=>
string(6) "flowed" } } } } } }

so is there a way of predicting what parts would be the body text ?
