Use quite parameter parsing:
if (zend_parse_parameters_ex(ZEND_PARSE_PARAMS_QUIET, ZEND_NUM_ARGS()
TSRMLS_CC, "lll", &m, &d, &y) != SUCCESS &&
zend_parse_parameters_ex(ZEND_PARSE_PARAMS_QUIET, ZEND_NUM_ARGS()
TSRMLS_CC, "llllll", &m, &d, &y, &h, &min, &s) != SUCCESS &&
zend_parse_parameters_ex(ZEND_PARSE_PARAMS_QUIET, ZEND_NUM_ARGS()
TSRMLS_CC, "llllll", &m, &d, &y, &h, &min, &s, &ms) != SUCCESS) {
php_error(E_WARNING, "Could not parse parameters");
}
Disadvantage is that you will not get the nicely formatted error
message and have to do it yourself.

Will let you check that there are 3, 6 and 7 parameters.

Hi.
From what I understand about the argument list for
zend_parse_parameters(), you separate optional parameters from
mandatory ones using pipe (|).
e.g.
if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "lll|llll", &m,
&d, &y, &h, &n, &s, &ms) == FAILURE) {
In the above example, this says that there are 3 mandatory parameters
and upto 4 optional parameters.
The prototype for this looks like ...
proto bool myExampleDateFunc(int month, int day, int year, [int hour
[, int min [, int sec [,int msec]]]])
Is there a way to make the prototype ...
proto bool myExampleDateFunc(int month, int day, int year, [int hour,
int min, int sec[, int msec]])
So, making this function accept 3 or 6 or 7 parameters only.
I'm guessing not, but I'm guessing. I think this has to be checked
using ...
switch (ZEND_NUM_ARGS()) {
after parsing the parameters and generate an error for
ZEND_NUM_ARGS = 4 or 5.

Richard.
