Question

我已将一些数据插入数据库，结果是数组，因此我需要将结果转换为字符串

这是我的结果

array(2) { 
   [0]=> array(1) {
          ["file_name"]=> string(38) "3848765-wallpaper-images-download1.jpg" 
       } 
   [1]=> array(1) { 
          ["file_name"]=> string(43) "6941202-smile-desktop-background-103791.jpg" 
       } 
}

我想要

3848765-wallpaper-images-download1.jpg,6941202-smile-desktop-background-103791.jpg

任何转换方式？提前谢谢!!!!!

Answer 1

试试这个有效

$data = [
    ["file_name" => "3848765-wallpaper-images-download1.jpg"], 
    ['file_name' => "6941202-smile-desktop-background-103791.jpg"]
];
echo implode(', ', array_column($data, 'file_name'));

Answer 2

没有转换器。你需要使用循环（例如foreach）并自己创建字符串。

<?php

$data = [
    ["file_name" => "3848765-wallpaper-images-download1.jpg"], 
    ['file_name' => "6941202-smile-desktop-background-103791.jpg"]
];

$output = [];
foreach ($data as $row) {
    $output[] = $row['file_name'];
}

echo implode(',', $output); // 3848765-wallpaper-images-download1.jpg,6941202-smile-desktop-background-103791.jpg
