php形成json语句，多出前面一句，怎么去掉！

php源码

$row['usrtype'],'sessionid'=>$usrname,'usrnm'=>$row['usrnm'],'usrid'=>$row['usrid']);										echo json_encode($jsonArr);										break;					}					else{						echo '{"logintype":"-1"}';						}				}			}				}?>

浏览器解析为

{"logintype":"0","sessionid":"0","usrnm":"mjc","usrid":"0"}

怎么将前一行去掉！

回复讨论(解决方案)

把相关程序文件转存为无bom的utf8文件就OK了。
方法最好用新建无bom文件，把代码复制过去，再保存。

php页面里去掉这句不就行了

json输出前加入

header('Content-type: application/json');

试试~

php页面里去掉这句不就行了

你找个地方去掉，我这个就没那个输出，估计是默认的，

include "./mobile/sql.php"; 这个里的吧

估计是 include "./mobile/sql.php"; 文件生成的吧，贴出来看看。

从来没有遇到过这样的奇葩问题了，呵呵

header("Content-type:application/json;charset=utf-8")

你肯定有include的页面里加这句了

咋去掉的啊 我也出现这种情况了
