我如何获取会话开始用户名以回显

Question

Iam having issues echoing the session username and have no idea were to start any more cause every thing i have tried keeps saying string to array conversion but idk how to get this to correctly work. here is the code that would check for the loged in saying you logged in would you like to log out.

 if(isset($_SESSION['username'])&& !empty($_SESSION['username'])){
    echo "<P id='loged'>your loged in would you like to log out</p>";

    echo'<a href="logout.php">log out</a>';





}else{
    include 'logform.php';
}

Answer 1

您可能想在$ _SESSION变量可用之前调用session_start() 。

Answer 2

您只想回显用户名？

echo "Hello " . $_SESSION['username];

Answer 3

I suppose the following answers your question...

echo $_SESSION['username'];

...but you will also want to use session_start() first.

Also, no need to use isset() and !empty(), as empty() checks if it is set first. All you really need is:

if(!empty($_SESSION['username']))

Answer 4

You forgot to mention session_start() in the begining.

session_start(); //add this in the begining of the file.


echo $_SESSION['username'];  //this will display username

Answer 5

Try this:

call the function session_start() at beginning of the page and then check the $_SESSION array using

echo '<pre>';
print_r($_SESSION);

after that you see all the indexes set in session variable.
