sort by key



a nice way to do sorting of a key on a multidimensional array without having to know what keys you have in the array first: "bob","age"=>,"colour"=>"red"), array("name"=>"greg","age"=>,"colour"=>"blue"), array("name"=>"andy","age"=>,"colour"=>"purple")); var_dump($people); example. sort an associative array in ascending order, according to the key: "","ben"=>"","joe"=>""); ksort($age); ?> run example »  return an object sorted by it's key var sortobjectbykey = function(obj){ var keys = []; var sorted_obj = {}; for(var key in obj){ if(obj.hasownproperty(key)){ keys.push(key); } } sort keys keys.sort(); create new array based on sorted keys jquery.each(keys, function(i, key){ sorted_obj[key] = obj[key]; }); return sorted_obj; };.

aller à key functions starting with python ., both list.sort() and sorted() added a key parameter to specify a function to be called on each list element prior to making comparisons. for example, here's a caseinsensitive string comparison: >>> sorted("this is a test string from andrew".split(), key=str.lower) ['a',  sort_by_key performs a keyvalue sort. that is, sort_by_key sorts the elements in [keys_first, keys_last) and [values_first, values_first (keys_last keys_first)) into ascending key order, meaning that if i and j are any two valid iterators in [keys_first, keys_last) such that i precedes j , and p and q are iterators in [values_first,  it can hold numbers, it can hold letters, it can be sorted, sliced and chunked. speaking of sorting, when sorting an array the straight forward sorting functions are only for sorting by the keys or by the values. what about when you have an array of arrays and want to sort be a specific key in the array?
