associative-array

问题 I have 2 tables set up something like below, what MySQL querys do I need to use to return assoc arrays of each entry along with it's associated fields? I've tried various JOINs but they all return a result for every item in the second table. Ultimately I want a parent array with one child array for each item in the first table. Each child array would contain the name from table A along with all the fields that belong to it from table B where B.entryID = A.ID. A ID |Name |Created 1 Jeff 2013

问题 Is there a possibility to create sth. like an associative array like in PHP? I don't plan to create a game with some player-data, but I could easily explain this way what I want: player["Name"] = "PName"; player["Custom"]["Gender"] = "Female"; player["Custom"]["Style"] = "S1"; player["Custom"]["Face"]["Main"] = "FM1"; player["Custom"]["Face"]["Eyes"] = "FE1"; player["Custom"]["Height"] = "180"; Also the length has to be dynamic , I don't how many keys there will be: player["key1"]["key2"]

问题 I have the following array of associative arrays. $result = array( (int) 0 => array( 'name' => 'Luke', 'id_number' => '1111', 'address' => '1544addr', 'time_here' => '2014-04-12 13:07:08' ), (int) 1 => array( 'name' => 'Sam', 'id_number' => '2222', 'address' => '1584addr', 'time_here' => '2014-04-12 14:15:26' I want to remove selected elements from this array such that it will look like this; array( (int) 0 => array( 'name' => 'Luke', 'id_number' => '1111' ), (int) 1 => array( 'name' => 'Sam'

问题 The title of this question is self-explanatory. I've heard I can mimic this using http_build_query, but I'd rather use a function that's meant for this. Input example: $assoc = array( "fruit" => "banana", "berry" => "blurberry", "vegetable" => "lettice" ); Desired output (I get this with http_build_query): string(46) "fruit=banana,berry=blurberry,vegetable=lettice" output from reversal wanted is the same as input - that's my current problem. 回答1: Implode with serialize($array); Explode with

问题 Suppose I have an associative array: $array = array( "key1" => "value", "key2" => "value2"); And I wanted to make the keys all uppercase. How would I do than in a generalized way (meaning I could apply a user defined function to apply to the key names)? 回答1: You can use the array_change_key_case function of php <?php $input_array = array("FirSt" => 1, "SecOnd" => 4); print_r(array_change_key_case($input_array, CASE_UPPER)); ?> 回答2: Amazingly, there's an array_change_key_case function. 回答3:

问题 I am trying to search a multi-dimensional associative array and change a value after searching. Here is what my array looks like $arr=Array ( [0] => Array ( [1] => Array ( [keyword] => 2014 [count] => 97 [percent] => 4.91 ))) So what I am trying to do is to search for keyword and if found then increase the count on that particular index where keyword was found. So I am trying to do something like: if(in_array("2014", $arr)) { //then add 100 to count that is 100+97 } So what will be the best

问题 I am using Bash 4.3 on linux. I have this simple YAML-esque data file: products: product1: name: "Product one" price: 100 product2: name: "Product two" price: 200 myList: - one - two And I need a shell function that, taking the above YAML file as input, can generate and then execute the below Bash code: unset products product1 product2 # declare the associative arrays declare -A product1 declare -A product2 # define the data product1=( [name]="Product 1" [price]=100 ) product2=( [name]=

问题 I'm trying to access a nested associative array: $data = array('1'=>'value1','2'=>'value2','3'=>array('one','two')) The value of the key '3' is an array. Since I need to cycle my values, I extracted the keys of given array: $keys = array_keys($data); and used to get the associated value with: foreach(range(1, 10) as $val): echo "key: ".$keys[$val]; echo "value: ".$data[$keys[$val]]; endforeach; Now I would like to access the values related to '3'. Using $data[$keys[$val]] won't work cause I

问题 I need to add the values of an associative array to another one. $a = array(4=>2,5=>5); $b = arrray(array(0=>0,1=>4,2=>10,3=>1000),array()...); What I'm expecting to get is a third array ($c) like the one below where the content of $b follows the content of $a: $c = array(array(4=>2,5=>5,0=>0,1=>4,2=>10,3=>1000),array(4=>2,5=>5....)); This is what I've written (not working): $c = array(); foreach ($possible_opp_action as $sub) { $c[] = array_push($to_merge,array_values($sub)); } 回答1: $a =

问题 I have a particular array of objects in js that represent columns of a table. My object is: var columns = { "image": { "show": false, "orderable": true, "value": 0, "displayOrder":2 }, "name": { "show": true, "orderable": true, "value": 1, "displayOrder":0 }, "company": { "show": false, "orderable": false, "value": 2, "displayOrder":1 } } I have to order the object by "displayOrder", but using a function like columns.sort(function(a, b) { return parseFloat(a.displayOrder) - parseFloat(b
