如何使用 php 解码此 json 数据以获取单个值。

{"Alpha":["A","B","C","D","E","F"],"Beta":["1","2","3" ],"Gamma": ["a","b","c"]}

【问题讨论】：

php.net/json_encode

标签： php arrays json multidimensional-array

【解决方案1】：

php有一个函数叫json_decode

$json = '{"Alpha":["A","B","C","D","E","F"],"Beta":["1","2","3"],"Gamma": ["a","b","c"]}';

$json_array = json_decode($json,TRUE); // personally I prefer arrays which the TRUE adds

$alpha = $json_array['Alpha'];

$first_alpha_value = $alpha[0];

printf("A == %s\n",$first_alpha_value);
