解码json并做一个foreach来获取每个数组的值？

Question

我是PHP新手，我有以下JSON，我想打印每个数组的值。

JSON

[ 
    ["38", "App Name1", "Long description.", "http:\/\/url.com", "5"], 
    ["12", "Name 2", "Long description goes here...", "http:\/\/test.com", "100"] 
] 

我想，因为它要打印：

 
App Name 1 
Long description 
http://url.com 
5 

Name 2 
Long description goes here... 
http://test.com 
100 

我无法得到它的工作。谁能帮我这个？

Answer 1

试试这个

$a='[ 
    ["38", "App Name1", "Long description.", "http:\/\/url.com", "5" 
    ], 
    ["12", "Name 2", "Long description goes here...", "http:\/\/test.com", "100" 
     ]  
    ]'; 
$ja=json_decode($a); 
if(count($ja)>0)foreach($ja as $jv){ 
    echo $jv[1]."<br/>"; 
    echo $jv[2]."<br/>"; 
    echo $jv[3]."<br/>"; 
    echo $jv[4]."<br/><br/>"; 
} 

output: 

App Name1 
Long description. 
http://url.com 
5 

Name 2 
Long description goes here... 
http://test.com 
100
