我如何解码这个Json数组使用PHP

Question

如何解码这个JSON数据使用PHP来获取单个值。 {“Alpha”：[“A”，“B”，“C”，“D”，“E”，“F”]，“Beta”：[“1”，“2”，“3” “]，” 伽马 “：[” 一”， “b”， “C”]}

Answer 1

PHP有一个称为函数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);
