如何以高级方式打印多维数组？

Question

以下是代码

print_r($_POST).'<br><br>';

foreach($_POST as $key => $value){
if(is_array($value))
{
    foreach($value as $key => $value)
    {
    echo "<br><br>".$key." ".$value."<br>";
    }
}
echo "<br>";
}

输出是

数组（[Cake_on_Name] =>数组（[0] => Rachana [1] => Sarika [2] => Pratik）[Cake_on_Date] =>数组（[0] => 2017-12-19 [1] => 2017-12-19 [2] => 2017-12-19）[Cake_on_Time] =>数组（[0] => 10 AM [1] => 10 AM [2] => 10 AM）[Cake_Receiver_Name] =>数组（[0] => [1] => [2] => Ashvin Ade）[Cake_on_Address] =>数组（[0] => [1] => [2] => Amravati）[pincode] =>数组（[0] => 444607 [1] => 444607 [2] => 444607）[cheu] => 1-1 @ 500,54-1 @ 1000,65-1 @ 1000,54-1 @ 300,56 -1 @ 1000,65-1 @ 300,54-1 @ 1000 [clientinput] =>添加细节和购买）

Answer 1

你可以试试这个。

$length = count($_POST["Cake_on_Name"]);
for($i=0; $i<=$length;$i++) {

foreach($_POST as $key => $value)
{
echo $i ." ". $value[$i]."<br>";
}

}

Answer 2

你把它放在<pre>标签。

echo '<pre>' . print_r( $_POST, 1 ) . '</pre>';

这只在html中显示这种方式。从命令行或如果文档格式为纯文本，它已打印出换行符。从网页输出，您还可以：

//this will also show all other content as standard text with line breaks.
header('Content-Type: text/plain');

Answer 3

你可以使用array_map并迭代结果。

$zipped = array_map(null, ...array_values($_POST));

foreach ($zipped as $item) {
    foreach ($item as $index => $value) {
        echo $index . ' ' . $value;
    }
}
