note 60822 added to function.array-filter

I have written a function that will filter an array by the frequency of element value in the array. This may be useful to some people. ///////////////////////////////////////////////////////////////// // Filter an array by value freguebcy // Input: $array // cut-off: $frequency (>=1) // result option option: 1=$frequency and higher // 0=$frequency only // -1=$frequency and lower ///////////////////////////////////////////////////////////////// function filter_array($array, $frequency = 2, $include = 1){ $freg = array_count_values($array); if($frequency<1){ print "** frequency cut-off should be >= 1! **\n"; return false; } foreach($freg as $k => $v){ if($include == 0){ if($frequency != $v){ $freg[$k] = 0; } }elseif($include > 0){ if($frequency > $v){ $freg[$k] = 0; } }else{ if($frequency < $v){ $freg[$k] = 0; } } } $filtered = array_filter($freg); $values = array_keys($filtered); return array_intersect($array,$values); } ---- Server IP: 12.160.245.96Probable Submitter: 67.133.232.202 ---- Manual Page -- http://www.php.net/manual/en/function.array-filter.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+60822 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+60822&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+60822&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+60822&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+60822&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+60822&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+60822&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+60822&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+60822&report=yes Search -- http://master.php.net/manage/user-notes.php
