我想在数组内的数组内打印字符串，所以它看起来更像这样：

鲍勃：球、球棒、汽车

丹尼尔：蝙蝠、熊、汽车

不像这样：

Bob：数组（[0] => 球 [1] => 球棒 [2] => 汽车）

丹尼尔：数组（ [0] => 蝙蝠 [1] => 熊 [2] => 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“字符串到数组转换”的错误。

您必须从数组中创建字符串，以便使用implode()并将其显示为字符串，如下所示。

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

替换print_r ($b["toy"]);为：

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