Answer 1

json_encode($arr);  //数组转json

Answer 2

这是你的那个代码，我应该怎么加上： json_encode($arr); //数组转json$s="绿色@@@/A/11/12/13/@@@/B/21/22/23/###蓝色@@@/A/31/32/33/@@@/B/41/42/43/###绿色@@@/A/51/52/53/@@@/B/61/62/63/";
foreach(explode('###',$s) as $v){
       $arr=explode('@@@',$v);
       $ar[array_shift($arr)]=$arr; 
}
print_r($ar);

Answer 3

echo json_encode($ar);   //加在最底下是什么结果

Answer 4

{null:["\/A\/51\/52\/53\/","\/B\/61\/62\/63\/"],null:["\/A\/31\/32\/33\/","\/B\/41\/42\/43\/"]} 

Answer 5

$s="绿色@@@/A/11/12/13/@@@/B/21/22/23/###蓝色@@@/A/31/32/33/@@@/B/41/42/43/###绿色@@@/A/51/52/53/@@@/B/61/62/63/";
foreach(explode('###',$s) as $v){
       $arr=explode('@@@',$v);
       $ar[array_shift($arr)]=$arr; 
}
echo json_encode($ar); 得出这样的结果,不对呀，怎么修改？？{null:["\/A\/51\/52\/53\/","\/B\/61\/62\/63\/"],null:["\/A\/31\/32\/33\/","\/B\/41\/42\/43\/"]}

中文成了 null 怎么转化呢？

Answer 8

中文丢失，是因为不是 utf-8 编码的原因连接数据库后，执行
mysql_query('set name utf8');
即可在其后取得 utf-8 编码的数据，再做成 json 就没有问题了
