array-merge

问题 I'm building an image gallery and want to throw some promo banners in at random points to promote certain offers to users. Given the following two arrays have been filtered from a database query: Media images array: Array ( [0] => Array ( [insertDate] => 2014-11-10 11:22:58 [keyword] => standard [mediaClass] => image [mediaURL] => http://image1.jpg [promoURL] => ) [2] => Array ( [insertDate] => 2014-11-10 11:23:18 [keyword] => standard [mediaClass] => image [mediaURL] => http://image3.jpg

问题 I have a $nr variable that as the number of arrays with the same name that i created in a previous function, something like this: $var = 'sorteios_'.$nr; $$var = array($sorteio_id); I have it in a While function so it was created something like 3 arrays with the names: $sorteios_1 , $sorteios_2 , $sorteios_3 And i want to add them inside an array_merge, so i have to use the $nr that says how many arrays with the same name were created. $nr = 3; i want that the final result looks something

问题 I have two multi-dimensional arrays: First array Pizzas: 0 => array:2 [▼ "pizza_id" => 11 "pizza_name" => "Hawaï" ] 1 => array:2 [▼ "pizza_id" => 12 "pizza_name" => "Tonno" ] 2 => array:2 [▼ "pizza_id" => 13 "pizza_name" => "Surprise" ] Second array Ingredients: 0 => array:4 [▼ "pizza_id" => 11 "ingredient_one" => "Ananas" "ingredient_two" => "Onion" "ingredient_three" => "Ham" ] 1 => array:4 [▼ "pizza_id" => 12 "ingredient_one" => "Tuna" "ingredient_two" => "Onion" "ingredient_three" => null

问题 Using PHP I need to merge 2 arrays (of equal length into one associative array) here is an excerpt from my current data set: [1] => Array ( [0] => C28 [1] => C29 ) [2] => Array ( [0] => 1AB010050093 [1] => 1AB008140029 ) both elements [1] and [2] are actually a lot longer than just 2 sub-elements (like I said, this is an excerpt). The deal is that "C28" in the first array corresponds to "1AB010050093" in the second array, and so on... The result I need is to create a new associative array

问题 I recently found a bug in my application caused by unexpected behaviour of array_merge_recursive . Let's take a look at this simple example: $array1 = [ 1 => [ 1 => 100, 2 => 200, ], 2 => [ 3 => 1000, ], 3 => [ 1 => 500 ] ]; $array2 = [ 3 => [ 1 => 500 ] ]; array_merge_recursive($array1, $array2); //returns: array:4 [ 0 => //... I expected to get an array with 3 elements: keys 1, 2, and 3. However, the function returns an array with keys 0, 1, 2 and 3. So 4 elements, while I expected only 3.

问题 What would be the best way to merge arrays nested in an array that shares at least an element ? Here's an example: some_method([[1, 2], [2, 3], [4, 5]]) #=> [[1, 2, 3], [4, 5]] some_method([[1, 2], [2, 3], [3, 4], [5,6]]) #=> [[1, 2, 3, 4], [5, 6]] 回答1: This would work: def some_method(arrays) h = Hash.new { |h, k| h[k] = [] } arrays.each do |array| tmp = h.values_at(*array).push(array).inject(:|) tmp.each { |k| h[k] = tmp } end h.values | h.values end Examples: some_method([[1, 2], [2, 3],

问题 I need to merge a new array of alternative information into the loop if they have the alternative information in their profile. Here's my loop: foreach ($doctor->getVars() as $k => $v) { $data['doctor_'. $k] = $v; } foreach ($patient->get_data() as $k=>$v) { if (is_string($v) || is_numeric($v)) $data["patient_" . $k] = strtoupper($v); } Here's the $data var_dump: Array ( [employee] => person [date] => 05/08/2013 [datetime] => 05/08/2013 9:41:15 AM [department] => stuff [employee_ext] => 7457

问题 I just saw this code while studying the wordpress source code (PHP), You can see they mergre/turn all get and post values into 1 request array. Now as I know it, $_GET and $_POST are already available by calling $_REQUEST WITHOUT using the array_merge() function, so any ideas why they would do this? $_REQUEST = array_merge($_GET, $_POST); 回答1: That is because the default $_REQUEST is a merger of $_GET , $_POST AND $_COOKIE . Also, the order in which the variables of these superglobals are

问题 Very frustrating moment and could not figure out and finally decided to move and ask to Geeks about solution. Okay, Here is the problem. I have below array and need to convert it by replacing repeating records from array and merge is as shown below.

问题 Actually i have two arrays as given below $array1=array('0'=>'abc','1'=>'xyz'); $array2=array('0'=>'pqr','1'=>'mno'); I want to two arrays first created with key[0] and second with key[1]. means should look like as follow $a1=array('0'=>'abc','1'=>'pqr'); $a2=array('0'=>'xyz','1'=>'mno'); The result must be $a1 = array ( '0' => $array1[0], '1' => $array2[0] ); $a2 = array ( '0' => $array1[1], '1' => $array2[1] ); 回答1: You try this code <?php $array1=array('0'=>'abc','1'=>'xyz'); $array2=array
