Question

我正在使用以下数组

 Array
 (
    [0] => Array
     (
        [id] => 6
        [key] => SITE_NAME
        [value] => Webg Smarty CMS Small
        [name] => general
        [title] => website name
        [type] => text
)

[1] => Array
    (
        [id] => 32
        [key] => PHONE_NUMBER
        [value] => 713-332-4675 
        [name] => general
        [title] => Phone Number
        [type] => text
    )

)

我想显示[0] [值]，[1] [值]

我正在使用foreach但我无法打印值

如何展示？

Answer 1

<?php
//$arr = your nested array aboe 
foreach($arr as $v){
  echo $v['value']; //this will print 'Webg Smarty CMS Small' first in your example followed by '713-332-4675'
}

$arr[0]['value'] will give you 'Webg Smarty CMS Small'
$arr[1]['value'] will give you '713-332-4675'

Answer 2

试试这个

foreach($yourArr as $key => $value)
{
  echo $value['value'];
}

OR

echo $yourArr[0]['value'];  //print value of first element
echo $yourArr[0]['key'];    //print key of first element

在PHP中打印多维数组的单值
