小编cod*_*ute的帖子

目前我正在使用这个

$big_test = array(
    'username' => 'test',
    'password' => 'test'

);

$test =  json_encode($big_test);    
echo $test;

结果是:

{"username":"test","password":"test"}

但是我的数据要包含在结果中,也许就是这个

{"Results":[{"username":"test","password":"test"}]}

我当前的json代码:

{"Results":[{"username":"test","password":"test"},{"username":"test","password":"test"},{"username":"google","password":"test"},{"username":"yahoo","password":"test"},{"username":"hotmail","password":"test"}]}

我想删除这个:

{"username":"google","password":"test"}

从使用PHP的代码.我尝试通过解码json到数组来删除但不能完成它.任何解决方案
