The problem is being able to show the current user name while someone is logged in. I have been trying some of the solutions I have found online and cannot get them to work. I will paste in a few of the significant files. All web page files are PHP and they are supported by a Dreamweaver CC template file. I am trying to get the active user name to show up in the navbar by putting the code in the template file.
The error reported in the browser for http://localhost/WEB182/index.php is: Parse error: syntax error, unexpected '' (T_ENCAPSED_AND_WHITESPACE), expecting identifier (T_STRING) or variable (T_VARIABLE) or number (T_NUM_STRING) in C:\xampp\htdocs\WEB182\index.php on line 91
Line 91 of the index.php file is: echo "Signed in as: '. $_SESSION['user_name']"; }
Of course, that is not necessarily the actual problem, but a symptom reflected in the browser generated error message.
This is the Dreamweaver template file and where I am trying to impliment the visual username:

That is probably more than enough as the only issue is the code for the username in the navbar found in the template file above.
Your syntax error is right here:
echo "Signed in as: '. $_SESSION['user_name']"; }
Convenience hint: Syntax highlighting helps spot these things a lot - on StackOverflow, the string is red; Can you see how $_SESSION is red too? Compare to the corrected version:
echo "Signed in as: ". $_SESSION['user_name'];
} // tidier down here
You had a stray quote (") at the end and mixed " with ' too.
Whenever working with strings in PHP, you can use either " or ' but not both at the same time:
Note that there's also differences between the two; using 'single quotes' is slightly faster than "doubles", but PHP takes everything in single quotes literally. Compare "\n" to '\n'.
What is the error actually saying?
So, text inside "double quotes" isn't taken literally. This is why you can do things like "Hello $name". In short, PHP spotted $_SESSION in your string but failed to go any further when it hit the square bracket.
