c - Can't load custom PHP module -

it compiles dll w/o problems. it's not being recognized loaded when use extension_loaded function in php or in phpinfo list. put dll extensions folder add it's entry php.ini. think problem may in code.

am missing or doing wrong?

zend_function(myfunction)  {      char var1 = null;     char var2 = null;     char var3 = null;     char var4 = null;     char var5 = null;     char var6 = null;     int var7;     double *var8;      if (zend_parse_parameters(zend_num_args() tsrmls_cc, "ssssssla", &var1, &var2,                                 &var3, &var4, &var5, &var6, &var7, &var8) == failure) {         return_null();     }      cfunction(&var1,&var2,&var3,&var4,&var5, &var6, var7, var8);      return_true; }  zend_function_entry myextension_functions[] = {     zend_fe(myfunction, null)     {null,null,null} };   php_minit_function(myextension) {     return success; }  php_mshutdown_function(myextension) {     return success; }  php_minfo_function(myextension) {     php_info_print_table_start();     php_info_print_table_header(2, "myextension v1.0", "");     php_info_print_table_row(2, "php extension", "enabled");     php_info_print_table_end(); }      zend_module_entry myextension_module_entry = { #if zend_module_api_no >= 20010901     standard_module_header, #endif     "myextension",      myextension_functions,     null,     null,     null,     null,     php_minfo(myextension),     "1.0",     standard_module_properties };      zend_get_module(myextension) 

the best way view extension loading errors run php.exe command line. showed me error messages of

warning: php startup: myextension: unable initialize module module compiled module api=20121212 php    compiled module api=20090626 these options need match  in unknown on line 0 

so found #define zend_module_api_no in zend_modules.h , changed 20121212 20090626.

then complained with:

warning: php startup: myextension: unable initialize module module compiled build id=api20090626,nts,vc10 php    compiled build id=api20090626,nts,vc9 these options need match  in unknown on line 0 

so found #define php_compiler_id in config.w32.h , changed "vc10" "vc9".

after loaded module. able call function came tradition 500 error. suspect has vc9/vc10 incompatibility.

the moral of story tried use extension compiled vc10 when php using compiled vc9. leads sorts of errors. appropriate thing compile php src vc10.
