This is a temporary location for a hacked-about version of the PHP extension for Spread (originally found on PECL here), mentioned in my article about LAMP and Spread on ONLamp.
You can download the source from here.
This works for me, but I make no guarantee as to its suitability, useability, compileability... or any other 'ability' for that matter.
Note #1: At this point I haven't made any changes to the code since the article.
Note #2: Contributed from Graeme Merrall, the original module can apparently be compiled (at least under OSX) by commenting out the line:
static unsigned char a2_arg_force_ref[] = { 2, BYREF_NONE, BYREF_FORCE };
However, using the module causes a segfault. If anyone using OSX has a positive experience, let me know and I'll post updates here.
Note #3:
Contributed from Christoph Dorn (thanks Christoph!), this package contains the necessary files to get the extension working for Mac OSX users.
