Issues?

What Isn’t Supported?

“If eval() is the answer, you’re almost certainly asking the wrong question. ” - Rasmus

Other methods of dynamic code generation (writing PHP code on the fly, Smarty, etc. )

$varname = “yellow”; $yellow = “Hello, World!n”; echo $$varname;

Others. . . create_function() preg_replace(‘/. */e’) *_exists($something) + conditional

So, who benefits from HPHP?

• Applications using > 2 servers to serve dynamic content • PHP applications that need source obfuscated • Use for code analysis to improve performance, even w/o HPHP deployment

Who does not benefit from HPHP?

• Sites w/ minimal traffic • Shared hosting • “PHP is rarely the bottleneck” - Rasmus • Most OSS project developers • Apps using PHP 5. 3 • Apps on 32 -bit systems • Windows users

Getting HPHP running is NOT easy!

Some suggestions if you want to use HPHP. . .

• Plan for crashes! • Use nginx in front of HPHP • Refresh your C++ knowledge • Be willing to help port extensions • Create your own build scripts • Use distcc if you can • Pay attention to known issues!

And now. . . the demo!
