Hello All, I am a beginner to PHP. I tried the following link "http://www.devarticles.com/c/a/Cplusplus/Developing-Custom-PHP-Extensions-Part-1/2/" to build a extension called php_devarticles.dll. I was successfully able to build it through Visual Studio 6.0 The hello_world.c which was a part of dll building looked like this -- /* include standard header */ /* you will need to include this in all of your php extension projects*/ #include "php.h" /* All the functions that will be exported (available) must be declared */ ZEND_FUNCTION(hello_world); PHP_MINFO_FUNCTION(devarticlesmod); /* Just a basic int to be used as a counter*/ int i; /* function list so that the Zend engine will know what’s here */ zend_function_entry devarticlesmod_functions[] = { ZEND_FE(hello_world, NULL) {NULL, NULL, NULL} }; /* module information */ zend_module_entry devarticlesmod_module_entry = { STANDARD_MODULE_HEADER, "DevArticles", devarticlesmod_functions, NULL, NULL, NULL, NULL, PHP_MINFO(devarticlesmod), NO_VERSION_YET, STANDARD_MODULE_PROPERTIES }; #if COMPILE_DL_DEVARTICLES_MOD ZEND_GET_MODULE(devarticlesmod) #endif PHP_MINFO_FUNCTION(devarticlesmod) { php_info_print_table_start(); php_info_print_table_row(2, "DevArticles Extension", "All Systems Go"); php_info_print_table_end(); } ZEND_FUNCTION(hello_world) { for(i=0;i<5;i++) { zend_printf("Hello World<br>"); } } When I build it and add to the ext directory where other dlls are present , and in php.ini I include extension=php_devarticlesmod.dll and also uncomment (just an example) extension=php_ldap.dll But during the IIS start-up i get the following error. [14-May-2009 20:49:04] PHP Warning: PHP Startup: Invalid library (maybe not a PHP library) 'php_devarticlesmod.dll' in Unknown on line 0 Please can anybody help me to tell wats wrong in this. just add more information: <? echo phpinfo(); echo sqrt(9); ?> works but php_devarticles.dll has a function called hello_world() -- <? hello_world(); ?> Does not work
