NOTE: This only affects CREATION time, NOT access time. It does NOT create a true indexed array (which is what I was hoping for) but is still associative like all PHP arrays. The class requires a numeric key because it builds the array with a set number of items but still operates under the hood associatively. (or this is my assumption, as I performed benchmarks comparing 100,000 reads on a standard array and an SplFixedArray: Results were the same, while a true indexed array SHOULD in theory be faster than an associative) The only performance gain is that you are not building the array piece by piece; Rather, the entire array is built at once and you can then fill it's values by numeric indexes... Therefor it is only reducing the creation overhead. This is only useful in a situation when you know the size your array will be, for example filling it with items from a database query. ---- Server IP: 69.147.83.197 Probable Submitter: 76.167.60.11 ---- Manual Page -- http://www.php.net/manual/en/class.splfixedarray.php Edit -- https://master.php.net/note/edit/95125 Del: integrated -- https://master.php.net/note/delete/95125/integrated Del: useless -- https://master.php.net/note/delete/95125/useless Del: bad code -- https://master.php.net/note/delete/95125/bad+code Del: spam -- https://master.php.net/note/delete/95125/spam Del: non-english -- https://master.php.net/note/delete/95125/non-english Del: in docs -- https://master.php.net/note/delete/95125/in+docs Del: other reasons-- https://master.php.net/note/delete/95125 Reject -- https://master.php.net/note/reject/95125 Search -- https://master.php.net/manage/user-notes.php
