Question

我想在数组中的数组内打印字符串，所以看起来更像是这样：

鲍勃：球，蝙蝠，汽车

丹尼尔：蝙蝠，熊，车

而不是这样：

鲍勃：排列（ [0] =＆gt;球 [1] =＆gt;蝙蝠 [2] =＆gt;汽车）

丹尼尔：排列（ [0] =＆gt;蝙蝠 [1] =＆gt;熊 [2] =＆gt;汽车）

<html>
<head>
<?php
$b;

$school=array(
"14"=>array("name"=>"Bob","toy"=>array("ball","bat","car")),
"23"=>array("name"=>"Daniel","toy"=>array("bat","bear","car")),
"31"=>array("name"=>"Tom","toy"=>array("bicycle","ball")),
"44"=>array("name"=>"Tim","toy"=>array("train","puzzle","ball","stick")),
"53"=>array("name"=>"Barbara","toy"=>array("bear", "car"))
);


foreach($school as $b)
{
echo $b["name"];
echo '<pre>';
print_r ($b["toy"]);
echo '</pre>';
}
?>
</head>
</html>

我尝试了很多东西，但我总是得到'字符串转换'错误。

Answer 1

你必须从数组中创建字符串，以便使用implode()并将其显示为如下的字符串。

foreach($school as $b)
{
    echo "$b[name] : ".implode(',',$b["toy"]);
}

Answer 2

将print_r ($b["toy"]);替换为：

echo implode(', ', $b["toy"] );

PHP：打印在数组中以数组形式写入的字符串
