note 96133 added to function.stats-stat-percentile

Has anyone come across a 'feature' of the function where by an array passed in is automatically sorted, and you lose any keys defined within the array? This happens if the array is a copy or the array is passed in via another function. If $tmpArray contains the following information: Array ( [51] => 150 [52] => 178 [53] => 116 [54] => 109 [61] => 45 [62] => 29 [63] => 26 [64] => 42 [71] => 32 [72] => 100 [73] => 120 [74] => 122 [81] => 54 [82] => 64 [83] => 51 [84] => 42 [91] => 46 [92] => 67 ) And you run the code below: list($percent05, $percent95) = percentiles($tmpArray); print "<pre>"; print_r($tmpArray); print "</pre>"; function percentiles($newArray) { $percent05 = stats_stat_percentile($newArray, 0.05); $percent95 = stats_stat_percentile($newArray, 0.95); return(array($percent05, $percent95)); } The outputted array is now: Array ( [0] => 26 [1] => 29 [2] => 32 [3] => 42 [4] => 42 [5] => 45 [6] => 46 [7] => 51 [8] => 54 [9] => 64 [10] => 67 [11] => 100 [12] => 109 [13] => 116 [14] => 120 [15] => 122 [16] => 150 [17] => 178 ) ---- Server IP: 78.110.173.36 Probable Submitter: 194.106.220.19 ---- Manual Page -- http://www.php.net/manual/en/function.stats-stat-percentile.php Edit -- https://master.php.net/note/edit/96133 Del: integrated -- https://master.php.net/note/delete/96133/integrated Del: useless -- https://master.php.net/note/delete/96133/useless Del: bad code -- https://master.php.net/note/delete/96133/bad+code Del: spam -- https://master.php.net/note/delete/96133/spam Del: non-english -- https://master.php.net/note/delete/96133/non-english Del: in docs -- https://master.php.net/note/delete/96133/in+docs Del: other reasons-- https://master.php.net/note/delete/96133 Reject -- https://master.php.net/note/reject/96133 Search -- https://master.php.net/manage/user-notes.php
