Re: Google optimizing PHP Par kinqpinz.infoLe [2009-06-26] à 22:54:14
Présentation : This is a quick script I wrote to test the points made in this Google developer video regarding fast(er|est) code execution in PHP. Turns out it's right on point. The short of the text and video is that you should use echo with the comma notation for printing strings (to avoid memory intensive string concatenating routines) and single quotes for strings. When PHP encounters double quotes it wants to first find and populate variables within that string, then move on to printing it, whereas single quotes move right along. Since I'm working on my OOP, here's an easy bench class that uses, in the alleged (now proven) slow test, double quotes with nested variables, and single quotes with echo and comma notation for appending variables in the fast test. If you wish to try it out, do it from the command line by making this code executable in a file that will accept its first argument, $argv[1], as the main loop amount. In short tests, the optimized PHP runs at double the speed. As the time lengthens, the gap is not so great but still quite tangible. Note the comments in the code's header to see my results on an old yet good laptop. [See link for code.]
