Removing Require_once

[#2Will]

The instructions given here:

http://framework.zend.com/manual/en/performance.classloading.html#performance.classloading.striprequires.sed

Don't work in terminal on OSX.   Does anyone have an alternative ?

Is it possible to make a production ready version of the framework available? one with the require_once statements removed. I know there is a bit of a discussion on here about it not mattering quite so much with php5.2+, but even so, it's one of the 1st instructions in the performance  chapter.

The documentation assumes GNU versions of find and sed, and should probably note that.  The equivalent BSD command (which will of course work on Mac OS X) is:

% cd path/to/ZendFramework/library

% find . -name '*.php' | grep -v './Loader/Autoloader.php' | \

xargs sed -E -i~ 's/(require_once)/\/\/ \1/g'

I've tested this and it works.  It might be good to add this to the documentation.

You'll need to delete all the backup versions of the files afterward with this command, BTW.  I don't think BSD sed will permit in-place editing using stdin.

The complete command is therefore:

% cd path/to/ZendFramework/library

% find . -name '*.php' | grep -v './Loader/Autoloader.php' | \

xargs sed -E -i~ 's/(require_once)/\/\/ \1/g'

% find . -name '*.php~' | xargs rm -f

Thanks! I got that working after a bit of fiddling with spaces etc. It made almost no difference to the page load time, even when applied to my extra application libraries, Doctrine etc. - its taking 600ms to proccess everything.(roughly, varies quite a bit - 1st load of a page a bit slower, posibly due to doctrine query caching kicking in on subsequant loads - who knows?)

XDebug should know.

Just a clarification: those recommendations were made based on testing
with PHP 5.2 series versions. Even with the realpath cache in PHP 5.2,
you get better performance after stripping require_once calls. However,
the most benefit comes from stripping them *and* using an opcode cache.
Without the opcode cache, the benefits, while measurable, are still
negligible.

Shouldn't this script be part of the ZF package?
