multidimensional-array

问题 I use this class method to return a nested/ multi-dimensional array, public function fetch_all_stmt($sql,$types = null,$params = null) { # create a prepared statement $stmt = parent::prepare($sql); if($stmt) { if($types&&$params) { $bind_names[] = $types; for ($i=0; $i<count($params);$i++) { $bind_name = 'bind' . $i; $$bind_name = $params[$i]; $bind_names[] = &$$bind_name; } $return = call_user_func_array(array($stmt,'bind_param'),$bind_names); } # execute query $stmt->execute(); # these

问题 This should be a failry simple question for a more experienced programmer. Im working on a basic "pickem app" which allows users to predict who lets users vote on who they believe will win a sports game. Simple enough. I wrote the following function to display statistics for each match. I.E the function returns how many votes each team received. Doing a print_r() on the function it works perfectly and returns the correct results. The results are returned in the form of a multidimensional

问题 I have a sub procedure that does the following: Looks For Duplicates in an array using the Dictionary object If a duplicate is found in the array, then provide a running count of that duplicate. The following is an example of what my sub returns: The Sub Works exactly as intended, so I translated it into a function, in order to use it in part of a program I am working on, but I cannot get my function to return results correctly. Below is my Sub that works: Sub GetRuningCounts() Dim dict As

问题 TL:DR Using PowerShell I want to split a string of text first by the new line character (\n), store it into an array, then split those array entries with a comma into a two-dimensional array. I am having trouble accessing (or possibly creating) any information in the second dimension. INFO: I have the following string (stored as $services ): SUPER-PC,Microsoft Office ClickToRun Service,ClickToRunSvc,C:\Program Files\Microsoft Office 15\ClientX64\OfficeClickToRun.exe /service,Auto SUPER-PC

问题 I have a CSV file with thousands of numbers underneath each other. Let's simplify by using this: 4 7 1 9 3 3 8 6 2 What I want is to output an array with 3 numbers per key (imploded by a comma): array ( [0] => 4,7,1 [1] => 9,3,3 [2] => 8,6,2 ) I've managed to get to this, reading the CSV: $path = "data.csv"; $row = 1; if (($handle = fopen($path, "r")) !== FALSE) { while (($data = fgetcsv($handle, 1000, "\r\n")) !== FALSE) { $cell = 0; $table[$row][$cell] = $data[0]; $cell++; } fclose($handle)

问题 I have the following problem in python: I have several numpy 2d-arrays where all have same number of columns ,but different number of rows.I want to index all these 2d-array in a unique numpy 3d-array where the first index keeps into account each 2d-array. For example : let's suppose I got two 2d-arrays like this : [[1,2,3][4,5,6][7,8,9]] (3X3 array) [[11,12,13][14,15,16]] (2X3 array) I want to get a numpy 3d-array name,for example, c where : c[0] has shape (3,3), c[1] (2,3) and so on...So I

问题 $stack = array(1,2,3,4,5,6,7,8,1,2,3,4,5,6,7,8); $myarr = array(array(),array()); $order = 4; $i = 1; $j = 1; foreach($stack as $value){ $myarr[$i][$j] = $value; if($j % $order == 0){ $j = 1; $i++; }else{ $j++; } } echo $myarr[1][2]; for ($i = 1; $i <= $order; $i++){ for($j = 1; $j <= $order; $j++){ echo $myarr[$i][$j]; echo " "; if($j % $order == 0){ echo "<br/>"; } } } *I want to convert one dimensional array to two dimensional with the existing element in php. Seems some problem while

问题 I have a multidimensional object array like this. var categories = [{ text: "engine", children: [1,2,3, { text: "piston", children: [4,5,6] }] }, { text: "tire", children: [7,8,9] }]; Everytime the index of the categories array equals an array there must be a dropdown menu with the contents of the array in it and it can be endless. If the index of the array is not equal to an array it should just be an a tag. I am trying to achieve something like this: https://www.w3schools.com/bootstrap

问题 I've got the following issue: I wrote a search function which results are being saved into an array. As i handle the response of that function with the jquery form plugin, i created an additional array which is filled with all of the arrays created by the search. Then, i want to parse that multi-array to my jQuery script as a JSON object. So far so good, but how do i make the multi-array accessable to the script? (Like multiarray.array1.property) Here is my code so far: [HTML / JS] <!DOCTYPE

问题 Let's say I have an array like this : 9 1 2 0 1 5 2 5 7 1 6 3 4 3 2 7 I want to be able to create a loop that goes through the array vertically and horizontally to see if there's any duplicates. For example, it will first check 9 1 7 4 to see if there's a dups. Then 1 5 1 3 and so on. After that, it'll do 9 1 2 0 (which will tell me there's a dup), then 1 5 2 5 7, etc etc. How can I do that? 回答1: While possible, a nested loops solution may not be the more straightforward way of solving it.
