Question

我在社交网络上工作，当我尝试触发session_start（）时;这是行不通的。我已经阅读了一些其他问题，显然是session_start（）;已被弃用。

这是我的index.php：

<?php
session_start();
if(!$_SESSION["myusername"]){
include("./assets/inc/nli-home.inc.php");
}
else {
include("./assets/inc/connect.inc.php"); 
include("./assets/inc/header.inc.php"); 
include("./assets/inc/posts.inc.php"); 
include("./assets/inc/header2.inc.php"); 
include("./assets/inc/footer.inc.php");
}
?>

这是checklogin.php的结尾，其中index.php是从以下位置重定向的：

// username and password sent from form 
$myusername=$_POST['myusername']; 
$mypassword=$_POST['mypassword']; 

// To protect MySQL injection (more detail about MySQL injection)
$myusername = stripslashes($myusername);
$mypassword = stripslashes(md5($mypassword));
$myusername = mysql_real_escape_string($myusername);
$mypassword = mysql_real_escape_string($mypassword);
$sql="SELECT * FROM $tbl_name WHERE username='$myusername' and password='$mypassword'";
$result=mysql_query($sql);

// Mysql_num_row is counting table row
$count=mysql_num_rows($result);

// If result matched $myusername and $mypassword, table row must be 1 row
if($count==1){

// Register $myusername, $mypassword and redirect to file "login_success.php"
$myusername = $_SESSION["myusername"];
$myusername = $_SESSION["mypassword"]; 
header("location:index.php");
}
else {
echo "Wrong Username or Password";
}
?>

真的很感激一些帮助！

checklogin.php也需要session_start()。

此外，在将任何输出发送到浏览器之前，必须先调用session_start()。页面上是否有前导"space"（在打开PHP标记之前）？

session_start未正确触发
