How can unexpected errors like "unexpected T_VARIABLE" in PHP echo statements be resolved when working with session data across multiple pages?

When working with session data across multiple pages in PHP, unexpected errors like "unexpected T_VARIABLE" in echo statements can occur if the variable is not properly enclosed in curly braces {}. To resolve this issue, ensure that variables are enclosed in curly braces within double quotes when using them in echo statements to avoid syntax errors. 

<?php
session_start();

// Assign a value to the session variable
$_SESSION['username'] = 'John';

// Use the session variable in an echo statement
echo "Welcome, {$_SESSION['username']}!";
?>
