I want to retrieve the json_decode data. How to write foreach here

本文关键字：在这里数据检索 json decode | 更新日期: 2023-11-27

$classconducted = json_encode(array('segment'=>$segment,'Board'=>$board,'classFiveSubject'=>$subject5,'classeightboard'=>$eightboard,'classeightsubject'=>$subject8,'classTenthboard'=>$tenthboard,'classTenthsubject'=>$subject8,'engineering'=>$engineering));

$in = '{"segment"：["I-V 类学费"，"VI-VIII 类学费"，"IX-X 类学费"]，"董事会"：["cbse"，"cse/Ise"，"State"]，"classFiveSubject"：["allsubject"，"science"]，"classeightboard"：["cbse"，"cse/Ise"]，"classeightsubject"：null，">

classTenthboard"：["cbse"，"cse/Ise"]，"classTenthsubject"：null，"engineering"：null}'; print_r( json_decode($in( (;

我的输出：

stdClass Object
(
    [segment] => Array
        (
            [0] => Class I-V Tuition
            [1] => Class VI-VIII Tuition
            [2] => Class IX-X Tuition
        )
    [Board] => Array
        (
            [0] => cbse
            [1] => cse/Ise
            [2] => State
        )
    [classFiveSubject] => Array
        (
            [0] => allsubject
            [1] => science
        )
    [classeightboard] => Array
        (
            [0] => cbse
            [1] => cse/Ise
        )
    [classeightsubject] =>
    [classTenthboard] => Array
        (
            [0] => cbse
            [1] => cse/Ise
        )
    [classTenthsubject] =>
    [engineering] =>
)
I have used the following code to retrieve the data. but I could not workout it.can any one guide me how to solve this?
       <?php
$sql=mysql_query("select * from tinfo");
while($row=mysql_fetch_array($sql))
{
$in=$row['classconducted'];
}
echo "<pre>";
$value=json_decode($in, true);//echo count($in); exit;
foreach ($value as $k => $val)    
{
echo "$k | $val <br />";
} 
?>

输出是：这里它列出了索引键，并且值没有出现如何在这里使用foreach。我想检索键和值。

segment | Array 
Board | Array 
classFiveSubject | Array 
classeightboard | Array 
classeightsubject | Array 
classTenthboard |  
classTenthsubject | Array 
engineering | Array 
I want the  output form my json_decode  like this:
segment:Class I-V Tuition
Board:CBSE,STATE
classFiveSubject:AllSubject,Maths,Science
segment:Class VI-VIII Tuition
Board:CBSE, STATE
classEightSUbject:AllSubject,Maths,Science

谁能给我正确的代码？列出json_decode数据的方法是什么。

未经测试，但请尝试：

foreach (json_decode($in, true) as $key => $val) {
  echo $key.': ';
  if (is_array($val))
    echo implode(',', $val) . "'n";
  else
    echo $val . "'n";
  
}

define('BR', '<br />');
$json = json_decode($in, true);
foreach ($json as $key => $arr ) {
    echo $key.BR;
    foreach( $arr as $value ) {
        echo $value.BR; 
    }
}
