note 86963 added to function.min

I have found a very useful trick to help get round the problem of setting a variable to max int when finding a min i.e. $val = 10; $min = 100000; // This is unpleasant and I couldn't find a equivalent to the C++ MAXINT if ($val < $min) { $min = $val; } try this ... $dataSet = Array(7, 8, 9, -1, -100, 0, 1, 2, 3, 5, 6); $min = true; $max = true; foreach ($dataSet as $data ) { echo("data = $data"); $min = min($data, $min); $max = max($data, $max); } echo("min = $min"); echo("max = $max"); $max can be set to anything e.g. "infinity", but the same trick doesn't work with min, however true does work (false doesn't). Not sure why though. The above code even works with a data set like this... $dataSet = Array("0.5", 1, 2, "3", "-1", "5"); but min doesn't like null or negative float e.g. "-1.2" and "" can give some odd results too. ---- Server IP: 92.48.74.199 Probable Submitter: 194.202.59.151 ---- Manual Page -- http://www.php.net/manual/en/function.min.php Edit -- https://master.php.net/note/edit/86963 Del: integrated -- https://master.php.net/note/delete/86963/integrated Del: useless -- https://master.php.net/note/delete/86963/useless Del: bad code -- https://master.php.net/note/delete/86963/bad+code Del: spam -- https://master.php.net/note/delete/86963/spam Del: non-english -- https://master.php.net/note/delete/86963/non-english Del: in docs -- https://master.php.net/note/delete/86963/in+docs Del: other reasons-- https://master.php.net/note/delete/86963 Reject -- https://master.php.net/note/reject/86963 Search -- https://master.php.net/manage/user-notes.php
