note 90371 added to class.arrayobject

According to my benchmarks, doing foreach() on an ArrayObject is significantly slower than doing so on a vanilla array(). However, inserting keys and retrieving them is almost the same speed. So, if performance is important, consider not using ArrayObject or descendant classes when you're iterating over its values a lot. These are my timing results, using PEAR::Benchmark: ArrayObject fill 0.01441502571106 ArrayObject read_key 0.018320083618164 ArrayObject read_foreach 2.1559031009674 array() fill 0.012364864349365 array() read_key 0.013092041015625 array() read_foreach 0.011217832565308 In all cases, 'fill()' inserts 10000 numbers at string keys, 'read_key()' reads all of those values by referencing the keys, and 'read_foreach()' does the same by walking through the array(object) with foreach(). As you can see, filling or reading from an ArrayObject by key is only 10% to 15% slower, but doing a foreach() is 200 times as costly. I am not sure what the cause of this may be. ---- Server IP: 83.137.20.135 Probable Submitter: 87.209.185.236 ---- Manual Page -- http://www.php.net/manual/en/class.arrayobject.php Edit -- https://master.php.net/note/edit/90371 Del: integrated -- https://master.php.net/note/delete/90371/integrated Del: useless -- https://master.php.net/note/delete/90371/useless Del: bad code -- https://master.php.net/note/delete/90371/bad+code Del: spam -- https://master.php.net/note/delete/90371/spam Del: non-english -- https://master.php.net/note/delete/90371/non-english Del: in docs -- https://master.php.net/note/delete/90371/in+docs Del: other reasons-- https://master.php.net/note/delete/90371 Reject -- https://master.php.net/note/reject/90371 Search -- https://master.php.net/manage/user-notes.php
