array-merge

问题 I have two arrays of arrays that have an id key, and I'd like to merge the data together based on that array's key and key value. The data would look something like: $color = [ ['id' => 1, 'color' => 'red'], ['id' => 2, 'color' => 'green'], ['id' => 3, 'color' => 'blue'], ]; $size = [ ['id' => 1, 'size' => 'SM'], ['id' => 2, 'size' => 'XL'], ['id' => 3, 'size' => 'MD'], ['id' => 4, 'size' => 'LG'], ]; $combined = [ ['id' => 1, 'color' => 'red', 'size' => 'SM'], ['id' => 2, 'color' => 'green',

问题 I've been having a little trouble trying to flatten arrays in a specific way. Here is a print_r view of the array I want to flatten: Array ( [1] => Array ( [8] => 1 [9] => 2 [10] => Array ( [15] => Array ( [22] => 1 ) [21] => 2 ) [11] => Array ( [16] => Array ( [23] => 1 ) ) ) [2] => Array ( [12] => 1 ) [3] => Array ( [13] => 1 ) [4] => Array ( [14] => 1 ) [5] => 5 [6] => 6 [7] => 7 ) What I'm attempting to create is an array which keeps the above indexes, but the value is equal to it's

问题 I have 3 arrays for storing posts,comments, and likes. These are the JSON strings: //comments JSON (stores user and comment points) $comments='[ { "user": "5", "points": "12" }, { "user": "2", "points": "1" }, { "user": "3", "points": "1" } ]'; //likes(stores user and likes point) $likes='[ { "user": "1", "points": 7 }, { "user": "4", "points": 4 }, { "user": "3", "points": 1 } ]'; //posts (stores user and post points) $posts='[ { "user": "1", "points": "6" }, { "user": "3", "points": "2" },

问题 for example I have a dictionary: dictA={"nest1":{"01feb":[1,2,3,4,5],"02feb":[1,7,8,9,10]}, "nest2":{"01feb":[1,2,3,4,5],"02feb":[6,4,8,10,10]}} the list inside has the same length. I need to merge nest1 and nest2 as one dictionary, and the result should be like this: dictA={"nest":{"01feb":[2,4,6,8,10],"02feb":[7,11,16,19,20]}} 回答1: Plese find the below code for your query. dictA={"nest1":{"01feb":[1,2,3,4,5],"02feb":[1,7,8,9,10]}, "nest2":{"01feb":[1,2,3,4,5],"02feb":[6,4,8,10,10]}} result

问题 I'm trying to merge data from a Wordpress feed with Google Analytics API data to create a table of Wordpress post information including each post's page views. I think I can match on the post url to accomplish this but I am not sure how to do this. I've spent a bit of time to get the data from the two sources to look like this: print_r($analytics); returns: Array ( [0] => Array ( [url] => blog-post-url-121 [pageViews] => 34326 ) [1] => Array ( [url] => blog-post-url-245 [pageViews] => 14642 )

问题 So consider an array with my 3 favorite fruits: $array1 = array("Apple", "Banana","Raspberry") I want to merge it with their own beautiful and natural color $array2 = array("Green ", "Yellow ","Red ") So that the results would look like ([0] => Green Apple [1] => Yellow Banane [2] => Red Raspberry) I need something to be scalable (2 to 6 keys, always the same between arrays) What I tried and results array_combine($array2,$array1) Result: Array ( [Green ] => Apple [Yellow ] => Banana [Red ] =>

问题 I got the following array: $arr = array(6 => 'Somedata', 7 => 'Somedata1', 8 => 'Somedata2'); The problem is that, when I use array_merge( (array) "Select the data", $arr); , it does change the array keys into: Array ( [0] => Not specified [1] => Somedata [2] => Somedata1 [3] => Somedata2 ) Is that possible to skip the array_merge key preversion so the output would look like this? Array ( [0] => Not specified [6] => Somedata [7] => Somedata1 [8] => Somedata2 ) 回答1: Use the + operator to

问题 I'd like to merge two arrays with each other: $filtered = array(1 => 'a', 3 => 'c'); $changed = array(2 => 'b*', 3 => 'c*'); Whereas the merge should include all elements of $filtered and all those elements of $changed that have a corresponding key in $filtered : $merged = array(1 => 'a', 3 => 'c*'); array_merge($filtered, $changed) would add the additional keys of $changed into $filtered as well. So it does not really fit. I know that I can use $keys = array_intersect_key($filtered, $changed
