96 | * Given a user-defined PHP function, create a PHP 'wrapper' function that can | ||
97 | * be exposed as xmlrpc method from an xmlrpc_server object and called from remote | ||
98 | * clients (as well as its corresponding signature info). | ||
99 | * | ||
100 | * Since php is a typeless language, to infer types of input and output parameters, | ||
101 | * it relies on parsing the javadoc-style comment block associated with the given | ||
102 | * function. Usage of xmlrpc native types (such as datetime.dateTime.iso8601 and base64) | ||
103 | * in the @param tag is also allowed, if you need the php function to receive/send | ||
104 | * data in that particular format (note that base64 encoding/decoding is transparently | ||
105 | * carried out by the lib, while datetime vals are passed around as strings) | ||
106 | * | ||
107 | * Known limitations: | ||
108 | * - requires PHP 5.0.3 + | ||
109 | * - only works for user-defined functions, not for PHP internal functions | ||
110 | * (reflection does not support retrieving number/type of params for those) | ||
111 | * - functions returning php objects will generate special xmlrpc responses: | ||
112 | * when the xmlrpc decoding of those responses is carried out by this same lib, using | ||
113 | * the appropriate param in php_xmlrpc_decode, the php objects will be rebuilt. | ||
114 | * In short: php objects can be serialized, too (except for their resource members), | ||
115 | * using this function. | ||
116 | * Other libs might choke on the very same xml that will be generated in this case | ||
117 | * (i.e. it has a nonstandard attribute on struct element tags) | ||
118 | * - usage of javadoc @param tags using param names in a different order from the | ||
119 | * function prototype is not considered valid (to be fixed?) | ||
120 | * | ||
121 | * Note that since rel. 2.0RC3 the preferred method to have the server call 'standard' | ||
122 | * php functions (ie. functions not expecting a single xmlrpcmsg obj as parameter) | ||
123 | * is by making use of the functions_parameters_type class member. | ||
124 | * | ||
125 | * @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... | ||
126 | * @param string $newfuncname (optional) name for function to be created | ||
127 | * @param array $extra_options (optional) array of options for conversion. valid values include: | ||
128 | * bool return_source when true, php code w. function definition will be returned, not evaluated | ||
129 | * bool encode_php_objs let php objects be sent to server using the 'improved' xmlrpc notation, so server can deserialize them as php objects | ||
130 | * bool decode_php_objs --- WARNING !!! possible security hazard. only use it with trusted servers --- | ||
131 | * bool suppress_warnings remove from produced xml any runtime warnings due to the php function being invoked | ||
132 | * @return false on error, or an array containing the name of the new php function, | ||
133 | * its signature and docs, to be used in the server dispatch map | ||

136 | * @todo finish using javadoc info to build method sig if all params are named but out of order | ||
137 | * @todo add a check for params of 'resource' type | ||
138 | * @todo add some trigger_errors / error_log when returning false? | ||
139 | * @todo what to do when the PHP function returns NULL? we are currently an empty string value... | ||

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

403 | * params and results. The generated php function will return an xmlrpcresp | ||
404 | * oject for failed xmlrpc calls | ||
405 | * | ||
406 | * Known limitations: | ||
407 | * - server must support system.methodsignature for the wanted xmlrpc method | ||
408 | * - for methods that expose many signatures, only one can be picked (we | ||
409 | * could in priciple check if signatures differ only by number of params | ||
410 | * and not by type, but it would be more complication than we can spare time) | ||
411 | * - nested xmlrpc params: the caller of the generated php function has to | ||
412 | * encode on its own the params passed to the php function if these are structs | ||
413 | * or arrays whose (sub)members include values of type datetime or base64 | ||
414 | * | ||
415 | * Notes: the connection properties of the given client will be copied | ||
416 | * and reused for the connection used during the call to the generated | ||
417 | * php function. | ||
418 | * Calling the generated php function 'might' be slow: a new xmlrpc client | ||
419 | * is created on every invocation and an xmlrpc-connection opened+closed. | ||
420 | * An extra 'debug' param is appended to param list of xmlrpc method, useful | ||
421 | * for debugging purposes. | ||
422 | * | ||
423 | * @param xmlrpc_client $client an xmlrpc client set up correctly to communicate with target server | ||
424 | * @param string $methodname the xmlrpc method to be mapped to a php function | ||
425 | * @param array $extra_options array of options that specify conversion details. valid ptions include | ||
426 | * integer signum the index of the method signature to use in mapping (if method exposes many sigs) | ||
427 | * integer timeout timeout (in secs) to be used when executing function/calling remote method | ||
428 | * string protocol 'http' (default), 'http11' or 'https' | ||
429 | * string new_function_name the name of php function to create. If unsepcified, lib will pick an appropriate name | ||
430 | * string return_source if true return php code w. function definition instead fo function name | ||
431 | * bool encode_php_objs let php objects be sent to server using the 'improved' xmlrpc notation, so server can deserialize them as php objects | ||
432 | * bool decode_php_objs --- WARNING !!! possible security hazard. only use it with trusted servers --- | ||
433 | * mixed return_on_fault a php value to be returned when the xmlrpc call fails/returns a fault response (by default the xmlrpcresp object is returned in this case). If a string is used, '%faultCode%' and '%faultString%' tokens will be substituted with actual error values | ||
