Question

我有2个2d数组（array1和array2），这是2个表，每个表有5列。

我需要通过添加数组2的列来编辑array1，以获得一个包含10列的表的arry

示例：

array1 [1,1,1,1,1]
       [2,2,2,2,2]
       [3,3,3,3,3]

array2 [a,a,a,a,a]
       [b,b,b,b,b]
       [c,c,c,c,c]

new array1 [1,1,1,1,1,a,a,a,a,a]
           [2,2,2,2,2,b,b,b,b,b]
           [3,3,3,3,3,c,c,c,c,c]

您可以迭代并使用Array#splice来连接其他值。

<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);

$mysql_host = "localhost";
$mysql_username = "root";
$mysql_password = "";
$mysql_database = "medvedgrad";

// First we create the connection
$pdo = new PDO("mysql:host=".$mysql_host .";dbname=".$mysql_database .";charset=utf8", $mysql_username, $mysql_password);
$pdo->setAttribute(PDO::ATTR_DEFAULT_FETCH_MODE, PDO::FETCH_ASSOC);
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);  

$data = json_decode(file_get_contents("php://input"));

$zm = $data->zlatni_medvjed;
$ck = $data->crna_kraljica;
$gv = $data->gricka_vjestica;
$dk = $data->dva_klasa;
$fk = $data->fakin;

//Let's do like Jack the ripper, lets divide  into parts :p

$updateparts = array();

$zm = trim($zm);
if($zm != "")
{
    $zmpart = "`zlatni_medvjed`=`zlatni_medvjed`+:zm";
    $updateparts[] = $zmpart;
}

$ck = trim($ck);
if($ck != "")
{ 
    $ckpart = "`crna_kraljica`=`crna_kraljica`+:ck";
    $updateparts[] = $ckpart;
}

$gv = trim($gv);
if($gv != "") 
{
    $gvpart = "`gricka_vjestica`=`gricka_vjestica`+:gv";
    $updateparts[] = $gvpart;
}

$dk = trim($dk);
if($dk != "") 
{
    $dkpart = "`dva_klasa`=`dva_klasa`+:dk";
    $updateparts[] = $dkpart;
}

$fk = trim($fk);
if($fk != "") 
{
    $fkpart = "`fakin`=`fakin`+:fk";
    $updateparts[] = $fkpart;
}

$updatepartstring = implode(",",$updateparts);

$update_query="UPDATE `stanje_piva`
 SET 
$updatepartstring 
WHERE `id`=1";



// Then we prepare, and execute the query
$stmt = $pdo->prepare($update_query);

 $stmt->execute(array("zm" => $zm, "ck" => $ck, "gv" => $gv, "dk" => $dk, "fk" => $fk));

?>

Answer 2

如果两个数组具有相同的长度，那么您可以安全地使用此

var arr1 = [[1,2,3], [4,5,6], [7,8,9]];
var arr2 = [["a","b","c"], ["d","e","f"], ["g","h","i"], ["j", "k","l"]];

var narr = [];
for(var ii = 0, len = Math.min(arr1.length, arr2.length); ii < len; ii++) {
   narr[ii] = arr1[ii].concat(arr2[ii]);
}

这将创建一个新数组，其长度等于两个数组的最小长度 arr1 ＆amp;的 ARR2

结果将是：

[1,2,3,"a","b","c"] [4,5,6,"d","e","f"] [7,8,9,"g","h","i"]

如果您不确定它们的长度是否相同，则可以直接更改为此代码

var arr1 = [[1,2,3], [4,5,6], [7,8,9]]; var arr2 = [["a","b","c"], ["d","e","f"], ["g","h","i"], ["j", "k","l"]]; var narr = []; for(var ii = 0, len = Math.max(arr1.length, arr2.length); ii < len; ii++) { narr[ii] = arr1[ii] ? arr1[ii].concat(arr2[ii]) : arr2[ii]; }

结果将是

[1,2,3,"a","b","c"] [4,5,6,"d","e","f"] [7,8,9,"g","h","i"] ["j","k","l"]

将colum从2d数组添加到另一个2d数组
