如何在PHP中调用和打印“多维数组函数”？

Question

我创建了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？这是针对在Apache2，MariaDB 10，PHP 7中运行的新的后端Web脚本编写的。这次，我尝试添加isset函数，但效果不佳。<?php//function Multidimentional Arrayfunction 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;?>我希望输出是“ Laptop”，15000、100，Baik，但实际输出为none。

Answer 1

我无法完全理解您的问题。但是根据我的理解，您需要这样的输出"Laptop",15000, 100, Baik

<?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'];

?>

Answer 2

您可以用来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);
