I get these errors for different DLLs which I try to install as PHP module. Do you have any clues how can I install it on Windows?

I've already installed some modules for example MONGO and it worked but I'm struggling with phalcon

Answer 1

When you are using a pre-compiled PHP extension for windows you must match the API numbers (PHP version), thread safety on or off (ZTS or NTS), and the version of Visual Studio used for the compile

PHP compiled with build ID=API20121212,NTS,VC9

This information tells you that the zend server version of PHP you're using was compiled with VC9, has thread safety off (NTS) and requires the 20121212 version of PHP's internal APIs

Module compiled with build ID=API20121212,NTS,VC11

This information tells you that the phalcon extension you downloaded was compiled with VC11 - but the API and thread safety settings are the same as the current PHP install. Because one of the three things doesn't match, however, the extension won't load correctly.

Unfortunately phalcon does not provide pre-compiled versions of the extension for PHP 5.5, NTS, built with VC9 so you'll either need to build your own or ask the maintainers to add that version

Or use something other than Zend Server for your PHP
