python - Serializing form data - picke or XML? -


i trying save form data, , wondering if should use python's native pickle, or sort of xml serializer. wanted use django's serializers these seem geared @ working wit models, not regular python dictionaries/objects.

the object want serialize composed entirely of strings (and possibly integers) , this:

data = { 'var1': "foo", 'var2': "bar", 'var3': ['bar', 'foo', 'moo', 'fish'], 'var4': 42 }

and want save because need able render html page based on these values @ point in future.

should go ahead saving pickled object - or should save xml? don't see advantages of using xml, since not planning access outside of django. making wrong decision?

few notes:

  • this not want save in session or cache, because want keep history of these forms indefinitely
  • the format/layout of forms subject change making db schema hold information impractical.

what json ? it's lightweight, readable, portable, , serialization/deserialization dead simple basic types (strings, ints, dicts, lists).

i try hard possible stick normalized db schemas, few occasions storing serialzed stuff "less worse" solution, go json, @ least can use data programming languages.

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
