apple,1=>bababa)),json_force_object);//string(18) [apple,bababa]

最后两行：
var_dump(json_encode((object)array(0=>apple,1=>bababa,2=>'pear')));// string(37) {0:apple,1:bababa,2:pear}var_dump(json_encode(array(0=>apple,1=>bababa,2=>'pear')),json_force_object);string(25) [apple,bababa,pear]int(16)

int (16) 是个啥？？加了json_force_object也不好使呢，如果下标不以0开头，或者key不连续，就是object，否则就是数组，哪位前辈给大概解释下为啥，为啥。
回复内容： apple,1=>bababa)),json_force_object);//string(18) [apple,bababa]

请仔细对比以下两行
var_dump(json_encode(array(0=>apple,1=>bababa,2=>'pear')),json_force_object);var_dump(json_encode(array(0=>apple,1=>bababa,2=>'pear'),json_force_object));
