What potential issue arises when using the same session variable to store multiple sets of data?

When using the same session variable to store multiple sets of data, there is a risk of data being overwritten or mixed up, leading to unexpected behavior in your application. To solve this issue, you can store multiple sets of data in an array within the session variable. This way, each set of data is organized and can be accessed separately without interfering with each other. 

// Start the session
session_start();

// Store multiple sets of data in an array within the session variable
$_SESSION['data_sets'] = [
    'set1' => ['key1' => 'value1', 'key2' => 'value2'],
    'set2' => ['key3' => 'value3', 'key4' => 'value4']
];

// Access and update specific data sets
$_SESSION['data_sets']['set1']['key1'] = 'new_value1';
$_SESSION['data_sets']['set2']['key4'] = 'new_value4';
