php - 如何将下面的字符串转成数据 键值对应 不使用 eval

Question

$str = 'array("1"=>"给对方","2"=>"发鬼地方","5"=>"","6"=>"发鬼地方","7"=>"发光飞碟");';

Answer 1

参考@oraoto

$str = 'array("1"=>"给对方","2"=>"发鬼地方","5"=>"","6"=>"发鬼地方","7"=>"发光飞碟");';
$s= str_replace(['array(','=>',');'],['{',':','}'],$str);
print_r(json_decode($s,1));
Array
(
    [1] => 给对方
    [2] => 发鬼地方
    [5] => 
    [6] => 发鬼地方
    [7] => 发光飞碟
)

Answer 2

思路：

1. 去掉开头的array(和最后的);，变成：

   '"1"=>"给对方","2"=>"发鬼地方","5"=>"","6"=>"发鬼地方","7"=>"发光飞碟"'

2. 把=>替换成:，变成：

   '"1":"给对方","2":"发鬼地方","5":"","6":"发鬼地方","7":"发光飞碟"'

3. 前后加{}，变成：

   '{"1":"给对方","2":"发鬼地方","5":"","6":"发鬼地方","7":"发光飞碟"}'

4. 上json_decode

Answer 3

用正则处理，前提是你的value里面不会有 => 这样的文字
