如何使用php解码此json数据以获得单个值。

｛"Alpha"：["A"、"B"、"C"、"D"、"E"、"F"]、"Beta"：["1"、"2"、"3"]、"Gamma"：["A"、"B"、"C"]｝

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);
