* Given a user-defined PHP function, create a PHP 'wrapper' function that can

||
|
|
* be exposed as xmlrpc method from an xmlrpc_server object and called from remote
|
||
|
|
* clients.
|
||
|
|
*
|
||
|
|
* Since php is a typeless language, to infer types of input and output parameters,
|
||
|
|
* it relies on parsing the javadoc-style comment block associated with the given
|
||
|
|
* function. Usage of xmlrpc native types (such as datetime.dateTime.iso8601 and base64)
|
||
|
|
* in the @param tag is also allowed, if you need the php function to receive/send
|
||
|
|
* data in that particular format (note that base64 enncoding/decoding is transparently
|
||
|
|
* carried out by the lib, while datetime vals are passed around as strings)
|
||
|
|
*
|
||
|
|
* Known limitations:
|
||
|
|
* - requires PHP 5.0.3 +
|
||
|
|
* - only works for user-defined functions, not for PHP internal functions
|
||
|
|
* (reflection does not support retrieving number/type of params for those)
|
||
|
|
* - functions returning php objects will generate special xmlrpc responses:
|
||
|
|
* when the xmlrpc decoding of those responses is carried out by this same lib, using
|
||
|
|
* the appropriate param in php_xmlrpc_decode, the php objects will be rebuilt.
|
||
|
|
* In short: php objects can be serialized, too (except for their resource members),
|
||
|
|
* using this function.
|
||
|
|
* Other libs might choke on the very same xml that will be generated in this case
|
||
|
|
* (i.e. it has a nonstandard attribute on struct element tags)
|
||
|
|
* - usage of javadoc @param tags using param names in a different order from the
|
||
|
|
* function prototype is not considered valid (to be fixed?)
|
||
|
|
*
|
||
|
|
* Note that since rel. 2.0RC3 the preferred method to have the server call 'standard'
|
||
|
|
* php functions (ie. functions not expecting a single xmlrpcmsg obj as parameter)
|
||
|
|
* is by making use of the functions_parameters_type class member.
|
||
|
|
*
|
||
|
|
* @param string $funcname the name of the PHP user function to be exposed as xmlrpc method; array($obj, 'methodname') might be ok too, in the future...
|
||
|
|
* @return false on error, or an array containing the name of the new php function,
|
||
|
|
* its signature and docs, to be used in the server dispatch map
|
||
|
|
*
|
||
|
|
* @todo decide how to deal with params passed by ref: bomb out or allow?
|
||
|
|
* @todo finish using javadoc info to build method sig if all params are named but out of order
|
||
|
|
* @done switch to some automagic object encoding scheme
|
||
|
|
* @todo add a check for params of 'resource' type
|
||
|
|
* @todo add some trigger_errors when returning false?
|
||
|
|
* @todo what to do when the PHP function returns NULL? we are currently returning bogus responses!!!

* Given an xmlrpc client and a method name, register a php wrapper function

||
|
|
* params and results. The generated php function will return an xmlrpcresp
|
||

|
* oject for failed xmlrpc calls
|
||
|
|
*
|
||
|
|
* Known limitations:
|
||
|
|
* - server must support system.methodsignature for the wanted xmlrpc method
|
||
|
|
* - for methods that expose many signatures, only one can be picked (we
|
||
|
|
* could in priciple check if signatures differ only by number of params
|
||
|
|
* and not by type, but it would be more complication than we can spare time)
|
||
|
|
* - nested xmlrpc params: the caller of the generated php function has to
|
||
|
|
* encode on its own the params passed to the php function if these are structs
|
||
|
|
* or arrays whose (sub)members include values of type datetime or base64
|
||
|
|
*
|
||
|
|
* Notes: the connection properties of the given client will be copied
|
||
|
|
* and reused for the connection used during the call to the generated
|
||
|
|
* php function.
|
||
|
|
* Calling the generated php function 'might' be slow: a new xmlrpc client
|
||
|
|
* is created on every invocation and an xmlrpc-connection opened+closed.
|
||
|
|
* An extra 'debug' param is appended to param list of xmlrpc method, useful
|
||
|
|
* for debugging purposes.
