How can one ensure proper context handling when adapting PHP code from older versions to newer versions like PHP 8?

When adapting PHP code from older versions to newer versions like PHP 8, it is important to review and update any deprecated functions, syntax, or features that may have changed. One common issue is with context handling, where functions may now require explicit context parameters. To ensure proper context handling, make sure to pass the correct context parameter when calling functions that require it. 

// Before PHP 8
$result = mysql_query("SELECT * FROM table");

// After PHP 8
$connection = mysqli_connect("localhost", "username", "password", "database");
$result = mysqli_query($connection, "SELECT * FROM table");
