note 85947 added to function.in-array

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... ---- Server IP: 64.71.164.2 Probable Submitter: 131.107.0.102 ---- Manual Page -- http://www.php.net/manual/en/function.in-array.php Edit -- https://master.php.net/note/edit/85947 Del: integrated -- https://master.php.net/note/delete/85947/integrated Del: useless -- https://master.php.net/note/delete/85947/useless Del: bad code -- https://master.php.net/note/delete/85947/bad+code Del: spam -- https://master.php.net/note/delete/85947/spam Del: non-english -- https://master.php.net/note/delete/85947/non-english Del: in docs -- https://master.php.net/note/delete/85947/in+docs Del: other reasons-- https://master.php.net/note/delete/85947 Reject -- https://master.php.net/note/reject/85947 Search -- https://master.php.net/manage/user-notes.php
