note 115211 added to function.max

Sometimes you could need to get the max from an array which looks like this: <?php $arrTest = array( array( "day" => 1, "b" => 10 ), array( "day" => 2, "b" => 43 ), array( "day" => 3, "b" => 2 ), array( "day" => 4, "b" => -3 ), array( "day" => 5, "b" => 4 ), array( "day" => 6, "b" => -5 ) ); ?> all max functions i see around don't provide a way to get the max value of the values in (example) key "b" <?php function maxValueInArray($array, $keyToSearch) { $currentMax = NULL; foreach($array as $arr) { foreach($arr as $key => $value) { if ($key == $keyToSearch && ($value >= $currentMax)) { $currentMax = $value; } } } return $currentMax; } // array key $value = maxValueInArray($arrTest, "b"); ?> output: 43 ---- Server IP: 81.88.49.41 Probable Submitter: 79.36.16.126 ---- Manual Page -- http://php.net/manual/en/function.max.php Edit -- https://master.php.net/note/edit/115211 Del: integrated -- https://master.php.net/note/delete/115211/integrated Del: useless -- https://master.php.net/note/delete/115211/useless Del: bad code -- https://master.php.net/note/delete/115211/bad+code Del: spam -- https://master.php.net/note/delete/115211/spam Del: non-english -- https://master.php.net/note/delete/115211/non-english Del: in docs -- https://master.php.net/note/delete/115211/in+docs Del: other reasons-- https://master.php.net/note/delete/115211 Reject -- https://master.php.net/note/reject/115211 Search -- https://master.php.net/manage/user-notes.php
