Php forms a json statement. how can I remove the preceding sentence! Php source code

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

The browser resolves

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

How can I remove the first line!

It is OK to convert the relevant program file to the utf8 file without bom.
The best way is to create a non-bom file, copy the code, and save it.

This sentence is not enough to be removed from the php page.

Before json output

Header ('content-type: application/json ');

Try ~

This sentence is not enough to be removed from the php page.

You can find a place to remove it. I don't have that output. it is estimated that it is the default one,

Include "./mobile/SQL. php ";

It is probably include "./mobile/SQL. php"; file generation. paste it and see it.

I have never encountered such a strange problem.

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

You must have added this sentence to the include page.

How can I remove it? this is also the case.
