Question

我正在创建一个称为多维数组的函数，我想将其打印到浏览器中。我需要在哪里展示？

这是针对新的后端Web脚本的，该脚本在Apache2，MariaDB 10，PHP 7中运行。这一次，我尝试添加isset函数，但效果不佳。

<?php

//function Multidimentional Array
function barang (){

$charles = [["nama_barang"=>"Laptop","harga"=>15000,"Qty"=>100,"Kondisi"=>"Baik"],["nama_barang"=>"Dekstop","harga"=>30000,"Qty"=>30,"Kondisi"=>"Buruk"],
["nama_barang"=>"Smartphone","harga"=>40000,"Qty"=>20,"Kondisi"=>"Baik Sekali"]];


}

//Print the result of Multidimentional Array called from function
$oke = barang();

echo $oke;

?>

我希望输出为“笔记本电脑”，15000、100，Baik，但实际输出为无。

Answer 1

我无法完全理解您的问题。但是据我了解，您需要像这样的"Laptop",15000, 100, Baik

输出

<?php

//function Multidimentional Array
function barang (){

$charles = [["nama_barang"=>"Laptop","harga"=>15000,"Qty"=>100,"Kondisi"=>"Baik"],["nama_barang"=>"Dekstop","harga"=>30000,"Qty"=>30,"Kondisi"=>"Buruk"],
["nama_barang"=>"Smartphone","harga"=>40000,"Qty"=>20,"Kondisi"=>"Baik Sekali"]];

return $charles;
}

//Print the result of Multidimentional Array called from function
echo '"' . barang()[0]['nama_barang'] . '" ,' .
 barang()[0]['harga'] . ' ,' .
 barang()[0]['Qty'] . ' , ' .
 barang()[0]['Kondisi'];

?>

这里是demo

Answer 2

您可以使用array_map在浏览器上打印它们

$charles = 
[["nama_barang"=>"Laptop","harga"=>15000,"Qty"=>100,"Kondisi"=>"Baik"], 
["nama_barang"=>"Dekstop","harga"=>30000,"Qty"=>30,"Kondisi"=>"Buruk"],
["nama_barang"=>"Smartphone","harga"=>40000,"Qty"=>20,"Kondisi"=>"Baik Sekali"]];

$res = array_map(function($v){
    return implode(',',$v); //echo implode(',',$v)
}, $charles);

echo '<pre>';
print_r($res);

如何在PHP中调用和打印“多维数组函数”？
