json_encode json_force_object問題

"APPLE",1=>"BABABA")),JSON_FORCE_OBJECT);//string(18) "["APPLE","BABABA"]"

最後兩行：

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) 是個啥？？加了json_force_object也不好使呢，如果下標不以0開頭，或者key不連續，就是object，否則就是數組，哪位前輩給大概解釋下為啥，為啥。

回複內容：

"APPLE",1=>"BABABA")),JSON_FORCE_OBJECT);//string(18) "["APPLE","BABABA"]"

最後兩行：

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) 是個啥？？加了json_force_object也不好使呢，如果下標不以0開頭，或者key不連續，就是object，否則就是數組，哪位前輩給大概解釋下為啥，為啥。

請仔細對比以下兩行

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));
