列出多个值逐个Mysql查询和php

Question

这是我的桌子。

Id              meta

1               {"stars":["Lucille Ball","Desi Arnaz","Vivian Vance","William Frawley"]}
2               {"stars":["Carol","Tudor Mandia"]}
3               {"stars":["Jony","Vandame"]}

我想得到这个：

        Lucille Ball
        Desi Arnaz
        Vivian Vance
        William Frawley
        Carol
        Tudor Mandia
        Jony
        Vandame

按顺序

。

怎么做？

您必须对每个元值进行JSON解码，然后从数组中获取所需的值：

<?php
    $query = "SELECT Id, meta FROM table1 ORDER BY Id";
    $result = mysqli_query($link, $query) or die(mysqli_error($link));
    while($row = mysqli_fetch_array($result,MYSQLI_ASSOC)){
        $meta = json_decode($row['meta'], true);
        foreach($meta['stars'] as $key=>$value){
            echo $value.'<br>';
        }
    }
?>

输出是：

Lucille Ball
Desi Arnaz
Vivian Vance
William Frawley
Carol
Tudor Mandia
Jony
Vandame
