php embedded

I am developing an embedded linux platform that will use apache + php.... I need a minimal version of PHP. Just for a test, I can compile with --disable-all and get a much smaller libphp5 (about 2.3M after stripping...) All I need php to do is to a) generate web pages (of course), b) handle a submitted form and write the results to a file or pipe, c) read a file or pipe and pre-fill a form based on data it reads. I also need i18n support for Asian, Arabic, Western European, and Slavic languages. I am not really sure if PHP builds libphp5.so with any other dependencies, but ideally I want no dependencies... I would appreciate any suggestions for building a minimal libphp.... Thanks, --Yan
