php源码

<?php	//session start	session_start();	include "./mobile/sql.php";	$con = mysql_connect($domain,$usrnm,$password);	mysql_select_db($usrnm) or die('Could not select database'); 	mysql_query("set character set 'utf8'");	$page = $_GET['page'];			if(!$con){				echo("can not connect");	}	else{		//1.登陆授权		if($page=='login'){			//1.读取用户数据，并进行匹配			$usrname = $_GET['usrnm'];			$pas			= $_GET['pas'];						//2.检索数据库			$sql = "select * from mb_usr";			$result = mysql_query($sql) or die('Query failed: ' . mysql_error());			while( $row = mysql_fetch_array($result) ){				 			   	if(($row['usrid']==$usrname || $row['mail']==$usrname || $row['phoneno']==$usrname) && $row['pas']==$pas){					//3.分配session值 保留登陆时限					$_SESSION[$usrname] = $usrname;										//4.构建login的json格式					$jsonArr = Array('logintype'=>$row['usrtype'],'sessionid'=>$usrname,'usrnm'=>$row['usrnm'],'usrid'=>$row['usrid']);										echo json_encode($jsonArr);										break;					}					else{						echo '{"logintype":"-1"}';						}				}			}				}?>

Copy after login

浏览器解析为

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">{"logintype":"0","sessionid":"0","usrnm":"mjc","usrid":"0"}

Copy after login

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")

Copy after login

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
