Answer 1

php有一个名为json_decode

的函数

$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);
