Php 二维阵列

我们有这些阵列

$cities = array("nagpur","kanpur","delhi","chd","Noida","mumbai","nagpur");
$names = array("munish","imteyaz","ram","shyam","ankit","Rahul","mohan");

现在我想要一个二维数组，其中城市名称作为键，所有对应的名称作为其值

<?php
$cities = array("nagpur","kanpur","nagpur","delhi","kanpur");
$names = array("ankit","atul","aman","amit","manu");
foreach ($cities as $i => $value) {
 echo "\n";

 echo $value;
 $city=$value;
 $k=0;
 foreach ($cities as $ii => $m) {
  If($city==$m)
 {
  echo$names[$ii] ;
  $final[$i][$k]=$names[$ii];


  $arr = array($city => array($k =>$names[$ii] ));
   $k++;
 }

 }
 echo"\n<tr></tr>";
}

我试过的是这个。但它不起作用。帮帮我，你不能指望PHP猜到如何配对它们，现在可以吗

你真正想做的是：

$final=array(
    "nagpur" => array("munish","imteyaz"),
    "kanpur" => array("ram","shyam"),
    etc.
);

然后，如果您还需要单独的数组，您可以构建那些迭代$final的数组，而不是相反

完整代码：

$final=array(
    "nagpur" => array("munish","imteyaz"),
    "kanpur" => array("ram","shyam"),
);

$cities=array();
$names=array();
foreach ($final as $city => $nnn) {
    array_push($cities,$city);
    foreach ($nnn as $nn) {
        array_push($names,$nn);
    }
}

试试这个：

<?php
$cities = array("nagpur","kanpur","nagpur","delhi","kanpur");
$names = array("ankit","atul","aman","amit","manu");

$arr = array();
foreach($cities as $key=>$city) {
    $arr[$city][] = $names[$key];
}
echo "<pre>";
print_r($arr);
?>

让我们知道它是怎么回事。

你怎么知道哪个名字属于一个城市？您能否举例说明结果数组的外观？您可以按照Johannes的建议使用array_combine，但这将创建一个一维数组，因此我不确定您想要什么…比如对于nagpur，值将是munish和mohanthnx：它工作正常。你能帮我再做一件事吗？就像我想按字母顺序对名字排序一样，&$values{sort$values；}应该排序。让我们知道它是否有效。同时，如果你做了你需要的事情，也要考虑给予一个赞成和接受的答案。
