How can PHP handle variable assignment within a text retrieved from a database to ensure proper parsing?

When retrieving text from a database that contains variables to be assigned, PHP can use the `sprintf` function to ensure proper parsing. By using placeholders in the text and passing the variables as arguments to `sprintf`, PHP can safely handle variable assignment within the text.

// Retrieve text from the database
$textFromDatabase = "Hello %s, your balance is $%d.";

// Assign variables
$name = "John";
$balance = 100;

// Use sprintf to handle variable assignment
$formattedText = sprintf($textFromDatabase, $name, $balance);

// Output the formatted text
echo $formattedText;
