如何在PHP中使用json_decode？

[{"Status":"FAILED","Message":"Trasaction Already Exist"}]

How to json_decode?

Currently using

$json=json_decode($response,true);
$status=$json["Status"];
$Message=$json["Message"];

but this is not working.

It is an array, you need to go to index 0. Use print_r or var_dump in the future to see what you have.

$json = json_decode('[{"Status":"FAILED","Message":"Trasaction Already Exist"}]', TRUE);
$status=$json[0]["Status"];
$Message=$json[0]["Message"];
