zend engine api 120020429

[Erik]

Which PHP version has Zend Engine API 20020429 ?
Installing the Zend Server/Debugger gives an error, complaining it is
confronted with a ZE API that is too new (20021010). It needs
20020429...

I have PHP 4.3.4 installed, but apparently need to down-grade

or maybe I need a newer Zend Server...
