Note Submitter: alishahnovin at hotmail dot com ---- To: Kureal at kkooporation dot de Are you sure about this? I am aware of the reasoning to use ++i over i++, but I've found that most compilers (I'm not sure about what PHP does...) will interpret ++i, i++, i+=1, i=i+1, all in the same way - ie. in modern compiled languages, these all are interpreted in the same way (except when incrementing before or after can cause a difference) Older languages don't regard them as the same, and thus it can produce different results in performance, but I think that's largely negligible - particularly when it comes down to the algorithm at hand. Big O notation.... And if you're dealing with a 1K dimensional array, you should probably focus your optimizations elsewhere.... like on limiting the dimensions of your array. If you have a 1K dimensional array, of length 100... you should focus on a better way of managing the data so you can optimize any functions performed on the array, such that you're not then iterating through such a massive array. ++i or i++ isn't the only improvement that can be done here...
