[PHP-DEV] adding functions to php4 ... From: Jinsoo Hwang (jshwang <email protected>)
Date: 08/11/00

Sorry to bug the list again, but this is my only resort at this moment.
:-)
The trouble is return value from PHP4 is wrong(way-off).
But the called function(pwilcox) in my library(/usr/local/lib/libstat.a)
works just fine by itself.
Could someone tell me what did I do wrong in the following source file.
It is only 70 line program. :-)
Here is my new function source( ext/stat/stat.c ) file
----------<stat.c>-----------------
#include "php.h"
#include "php_ini.h"
#include "php_stat.h"

#if HAVE_STAT
*/
function_entry stat_functions[] = {
        PHP_FE(p_wilcox, NULL)
        {NULL, NULL, NULL}
};
 
zend_module_entry stat_module_entry = {
        "stat",
        stat_functions,
        PHP_MINIT(stat),
        PHP_MSHUTDOWN(stat),
        NULL,
        NULL,
        PHP_MINFO(stat),
        STANDARD_MODULE_PROPERTIES
};
#ifdef COMPILE_DL_STAT
ZEND_GET_MODULE(stat)
#endif
 
PHP_MINIT_FUNCTION(stat)
{
        return SUCCESS;
}
 
PHP_MSHUTDOWN_FUNCTION(stat)
{
        return SUCCESS;
}
 
PHP_MINFO_FUNCTION(stat)
{
        php_info_print_table_start();
        php_info_print_table_header(2, "stat support", "enabled");
        php_info_print_table_end();
 
}

PHP_FUNCTION(p_wilcox)
{
zval **x, **m, **n, **lower_tail, **log_p ;
double a, b, c;
int t, p;
double d ;
 
if (ZEND_NUM_ARGS() != 5 || zend_get_parameters_ex
   (5, &x, &m, &n, &lower_tail, &log_p) == FAILURE) {
   WRONG_PARAM_COUNT;
   }
 
convert_to_double_ex(x);
convert_to_double_ex(m);
convert_to_double_ex(n);
convert_to_long_ex(lower_tail);
convert_to_long_ex(log_p);
 
a = (*x)->value.dval;
b = (*m)->value.dval;
c = (*n)->value.dval;
t = (*lower_tail)->value.lval;
p = (*log_p)->value.lval;
 
d =(double) pwilcox(a,b,c,t,p);
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
printf("ret_pvalue=>%f\n", d);
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
RETURN_DOUBLE((double)d);
^^^^^^^^^^^^^^^^^^^^^^^^^^
}
 
#endif /* HAVE_STAT */
----------------------------------------------

Whenever I try to test my new function(p_wilcox) by calling
> php -f ext/stat/stat.php

THe return value is something like 1121872.
But the pwilcox function itselt works just fine without php4.
There must be something basic I do wrong here but I couldn't find them.
Thnaks in advance.
