Re: What is "module_number"?

I figured it out ... I used rawsockets_module_entry.module_number, and that seems to work just fine. My extension is now up and running and seems to be functioning properly. :0) Nick Nicholas Williams wrote:

I got it working. Turns out "#if HAVE_RAWSOCKETS" will evaluate to true in php_rawsockets.h but to false in rawsockets.c. Not sure why this is, but when I took "#if HAVE_RAWSOCKETS" out of rawsockets.c (and left it in php_rawsockets.h), it started working. I get the right output from nm now, PHP loads the extension, it prints phpinfo() information as requested ... all in all, it works well. Now, I have another question. There's a little-documented integer called module_number that is implicitly declared inside the PHP_MINIT_FUNCTION. However, module_number does not seem to be available inside a PHP_FUNCTION, and I need it to be. Does anyone know what exactly this variable is and does and how I can have it made available inside a PHP_FUNCTION? Thanks, Nick Nicholas Williams wrote:

You were right, my .so does not have get_module(): $ nm -o rawsockets.so rawsockets.so: 00000000 s __mh_bundle_header

rawsockets.so:          U dyld_stub_binder

However, in my source file rawsockets.c, I have the following: #ifdef COMPILE_DL_RAWSOCKETS ZEND_GET_MODULE(rawsockets) #endif Which is nearly identical to that in the sockets extension, sockets.c: #ifdef COMPILE_DL_SOCKETS ZEND_GET_MODULE(sockets) # ifdef PHP_WIN32 # include "zend_arg_defs.c" # endif #endif And after phpize and configure I can grep the directory and find COMPILE_DL_RAWSOCKETS in about a dozen files. Just to be safe, however, I commented out #ifdef COMPILE_DL_RAWSOCKETS and it nm -o rawsockets.o still doesn't report a get_module() available. *scratches head* N Rasmus Lerdorf wrote:

for Mac OS X Snow Leopard 10.6.2. It compiles without error and says that the extension has been copied to the proper directory. However, if I try to load the extension either with dl('rawsockets.so') or extension=rawsockets.so in the INI file, I get the error "PHP Warning: PHP Startup: Invalid library (maybe not a PHP library) 'rawsockets.so' in Unknown on line 0 phpinfo()". If, per some suggestions I found online, I try to load it with zend_extension=/usr/lib/php5/extensions/rawsockets.so, I get the error "/usr/lib/php5/extensions/rawsockets.so doesn't appear to be a valid Zend extension."

This happens when your .so does not have get_module(). Check it with: nm -o rawsockets.so | grep get_module -Rasmus
