array-merge

问题 I've found a lot of information on joining arrays together using array_merge , but I'm wondering how easy it is to merge multiple arrays in order of their value index, rather than simply joining them together. For example, if we had the following three arrays: $a = array('One','Two','Three','Four'); $b = array(1,2,3,4); $c = array('i','ii','iii','iv'); Could we merge them into?: One,1,i,Two,2,ii,Three,3,iii,Four,4,iv Instead of: One, Two, Three, Four, 1, 2, 3, 4, i, ii, iii, iv 回答1: you can

问题 I am trying to merge an array with an input from a form of a random string of numbers In my form I have <input type="text" name="purchase_order_number" id="purchase_order_number" value="{{ $purchase_order_number }}" /> And in the controller: public function store(CandidateRequest $request) { $candidateInput = Input::get('candidates'); $purchaseOrderNumber = Input::get('purchase_order_number'); foreach ($candidateInput as $candidate) { $data = array_merge($candidate, [$purchaseOrderNumber]);

问题 My goal is to merge 2 different arrays. I have table "a" & "b". Data from table "a" are more prioritar. PROBLEM : if a key from "a" contains an empty value, I would like to take the one from table "b". Here is my code: <?php $a = array('key1'=> "key1 from prioritar", 'my_problem'=> ""); $b = array('key1'=> "key1 from LESS prioritar", 'key2'=>"key2 from LESS prioritar", 'my_problem'=> "I REACHED MY GOAL!"); $merge = array_merge($b, $a); var_dump($merge); Is there a way to do this in one

问题 I'm looking for JQ query that allows me to merge 2 arrays variables (not files) and also take me to overwrite first array with newer value from second array. For example: #!/bin/bash -e firstArrayVariable=' [ { "Key": "A B", "Value": "1 2" }, { "Key": "C D", "Value": "3 4" }, { "Key": "E F", "Value": "5 6" }, { "Key": "G H", "Value": "9 10" } ] ' secondArrayVariable=' [ { "Key": "A B", "Value": "1 2" }, { "Key": "C D", "Value": "3 4" }, { "Key": "G H", "Value": "11 12" }, { "Key": "J K",

问题 How can I merge these two array together? Array ( [0] => Array ( [id] => 5 [cnt] => 14 ) [1] => Array ( [id] => 8 [cnt] => 2 ) ) Array ( [0] => Array ( [id] => 8 [binding] => hardcover ) [1] => Array ( [id] => 5 [binding] => softcover ) ) The expected result is: Array ( [0] => Array ( [id] => 5 [binding] => softcover [cnt] => 14 ) [1] => Array ( [id] => 8 [binding] => hardcover [cnt] => 2 ) ) The merge of these two array should happen on the [id] value and not on any sort of the array. How

问题 I'm trying to prepend an item to the beginning of an associative array. I figured the best way to do this is to use array_merge, but I'm having some odd consequences. I get the id and Name of products from a mysql database, and it gets returned as an associative array, like this (not the actual data coming back, but sample data for this question that represents what the data looks like approximately): $products = array (1 => 'Product 1', 42 => 'Product 42', 100 => 'Product 100'); this is

问题 How can make it so array_merge() overwrites two keys with different values but same key index from two arrays? for example, merging: [0] => 'whatever' with [0] => 'whatever', [1] => 'a', [2] => 'b' should produce [0] => 'whatever', [1] => 'a', [2] => 'b' Basically I want array_merge to bahave the same way it behaves if the arrays have string keys... 回答1: Use the + operator. Compare array_merge to + operator: <?php $a1 = array(0=>"whatever",); $a2 = array(0=>"whatever",1=>"a",2=>"b"); print_r

问题 Suppose we have the following 3 arrays in Julia: 5.0 3.5 6.0 3.6 7.0 3.0 5.0 4.5 6.0 4.7 8.0 3.0 5.0 4.0 6.0 3.2 8.0 4.0 I want to merge the 3 arrays in one array, by common values of the first column, summing the values of the second column. The result must be the following array: 5.0 12 6.0 11.5 7.0 3.0 8.0 7.0 I tried vcat and reduce but I don't get the pretended result. Is there a relatively simple way to code the instructions, avoiding a time-consuming code? Thank you! 回答1: Given the

问题 I have an array mentioned below. $array = array( '0' => array( 'names' => array(0 => 'Apple'), 'group' => 1 ), '1' => array( 'names' => array(0 => 'Mango'), 'group' => 1 ), '2' => array( 'names' => array(0 => 'Grapes'), 'group' => 1 ), '3' => array( 'names' => array(0 => 'Tomato'), 'group' => 2 ), '4' => array( 'names' => array(0 => 'Potato'), 'group' => 2 ) ); I want the result in such a way that the if the value of the array key "group" is same then the values of the key "names" should be

问题 I have array like as follow, Array( [0] => Array( [account] => 251234567890, [price] => 83 ) [1] => Array( [account] => 251234567890, [price] => 27 ) [2] => Array( [account] => 251234564526, [price] => 180 ) [3] => Array( [account] => 251234567890, [price] => 40 ) ) now with i want to merge array with same account and sum of it's particular price . I want output array like this, Array( [251234567890] => Array( [account] => 251234567890, [price] => 150 ) [251234564526] => Array( [account] =>
