注意:在第8行数组C:\ xampp \ htdocs \ example \ echo.php中将数组转换为字符串

问题描述

<?php
    $products = array();    
    $products[101] = array(
        "name" => "Logo Shirt, Red",
        "price" => 18,
        "img" => "img/shirts/shirts-101.jpg"
);
    echo $products;
?>

我正在尝试运行此php文件，并且一直在给我这个错误- 注意:第8行数组在C:\ xampp \ htdocs \ example \ echo.php中将数组转换为字符串.

I am trying to run this php file and it keeps giving me this error - Notice: Array to string conversion in C:\xampp\htdocs\example\echo.php on line 8 Array.

我要做的就是回显数组中的每个元素.我也尝试过

All i want to do is echo out each and every element inside the array.I've also tried

<?php
    $products = array();    
    $products[101] = array(
        "name" => "Logo Shirt, Red",
        "price" => 18,
        "img" => "img/shirts/shirts-101.jpg"
    );
    foreach($products as $product){
        echo $product;
    }
?>

好的，如果有多个类似的数组，该怎么办 $产品[101] $ product [102] $ product [103] $ product [104] . . . $ product [n]

okay guys what if there are multiple similar arrays like $product[101] $product[102] $product[103] $product[104] . . . $product[n]

那又是什么?

推荐答案

如果您echo一个数组，它将给您一个错误，或者仅输出"Array".

If you echo an array, it will either give you an error or just output "Array".

在第二个示例中，$products[101]也是也是数组.

In your second example, $products[101] is also an array.

因此您可以执行以下操作:

So you can do this:

foreach($products as $product){
    foreach($product as $key => $val){
        echo "$key: $val";
    }
}

或使用print_r将数据输出为数组:

Or use print_r to output the data in an array:

foreach($products as $product){
    print_r($product);
}
