note 92214 added to class.splfixedarray

Note, that this is considerably faster and should be used when the size of the array is known. Here are some very basic bench marks: <?php for($size = 1000; $size < 50000000; $size *= 2) { echo PHP_EOL . "Testing size: $size" . PHP_EOL; for($s = microtime(true), $container = Array(), $i = 0; $i < $size; $i++) $container[$i] = NULL; echo "Array(): " . (microtime(true) - $s) . PHP_EOL; for($s = microtime(true), $container = new SplFixedArray($size), $i = 0; $i < $size; $i++) $container[$i] = NULL; echo "SplArray(): " . (microtime(true) - $s) . PHP_EOL; } // OUTPUT Testing size: 1000 Array(): 0.00046396255493164 SplArray(): 0.00023293495178223 Testing size: 2000 Array(): 0.00057101249694824 SplArray(): 0.0003058910369873 Testing size: 4000 Array(): 0.0015869140625 SplArray(): 0.00086307525634766 Testing size: 8000 Array(): 0.0024251937866211 SplArray(): 0.00211501121521 Testing size: 16000 Array(): 0.0057680606842041 SplArray(): 0.0041120052337646 Testing size: 32000 Array(): 0.011334896087646 SplArray(): 0.007631778717041 Testing size: 64000 Array(): 0.021990060806274 SplArray(): 0.013560056686401 Testing size: 128000 Array(): 0.053267002105713 SplArray(): 0.030976057052612 Testing size: 256000 Array(): 0.10280108451843 SplArray(): 0.056283950805664 Testing size: 512000 Array(): 0.20657992362976 SplArray(): 0.11510300636292 Testing size: 1024000 Array(): 0.4138810634613 SplArray(): 0.21826505661011 Testing size: 2048000 Array(): 0.85640096664429 SplArray(): 0.46247816085815 Testing size: 4096000 Array(): 1.7242450714111 SplArray(): 0.95304894447327 Testing size: 8192000 Array(): 3.448086977005 SplArray(): 1.96746301651 ---- Server IP: 208.69.120.35 Probable Submitter: 64.202.160.65 ---- Manual Page -- http://www.php.net/manual/en/class.splfixedarray.php Edit -- https://master.php.net/note/edit/92214 Del: integrated -- https://master.php.net/note/delete/92214/integrated Del: useless -- https://master.php.net/note/delete/92214/useless Del: bad code -- https://master.php.net/note/delete/92214/bad+code Del: spam -- https://master.php.net/note/delete/92214/spam Del: non-english -- https://master.php.net/note/delete/92214/non-english Del: in docs -- https://master.php.net/note/delete/92214/in+docs Del: other reasons-- https://master.php.net/note/delete/92214 Reject -- https://master.php.net/note/reject/92214 Search -- https://master.php.net/manage/user-notes.php
