In this article, we are going to concentrate on coding techniques, and use Xdebug to measure the performance of different scriptlets. We ran the codes several times and took the average execution time to create our benchmark.

The fastest is probably

echo "Hello ", "World";

if you have to echo two seperate strings/variables, as this avoids having to concatenate the strings. However, the difference is probably unnoticeable for any reasonable sized application.

But remember

Premature optimization is the root of all evil - Donald Knuth

However, it is nice to know the echo-comma syntax and use it where possible.

If you are running on Apache, you can use eAccelerator, which will cache the compiled and optimized bytecode produced by the PHP parser, effectively removing the parsing step after the first hit to each script. On my blog's Wordpress install, this halves (!) the loading time of each page.

If you are trying to optimize the actual running time of your script, you will have to follow the standard wisdom: profile your code, find the bottlenecks, optimize them somehow, and repeat until the script is as fast as you need it to be.
