Question

I have this array.

$test['color'][0] = "red";
$test['color'][1] = "blue";
$test['color'][2] = "black";
$test['plug'][3] = "US";
$test['plug'][4] = "UK";

我想从上面的数组中实现这个目标。

$test2['color'] = "red,blue,black"; 
$test2['plug'] = "US,UK";

实现这一目标的最佳逻辑是什么。

Answer 1

你可以很好地使用一些逻辑和一些PHP函数：

<?php

    $array['color'][0] = "red";
    $array['color'][1] = "blue";
    $array['color'][2] = "black";
    $array['plug'][3] = "US";
    $array['plug'][4] = "UK";
    $test2=array();
    foreach($array as $key=>$val)
    {
        $test2[$key]=implode(',',$val);
    }

    print_r($test2);
?>

输出：

Array
(
    [color] => red,blue,black
    [plug] => US,UK
)

编辑：第一个答案是错误的，过于复杂。这是一种控制结构解决方案。

Answer 2

$test2['color'] = implode(',', $test['color']);
$test2['plug'] = implode(',', $test['plug']);

print_r($test2);
