In the context of PHP and database interactions, what role does data type conversion play in ensuring the accurate display of numeric values in input fields?

When retrieving numeric values from a database and displaying them in input fields in a form, it is important to ensure that the data type is properly converted to a string to display accurately. This conversion helps prevent any unexpected behavior or errors that may occur due to mismatched data types. By explicitly converting numeric values to strings before outputting them in input fields, you can ensure that the values are displayed correctly.

// Retrieve numeric value from database
$numericValue = 123;

// Convert numeric value to string before displaying in input field
$numericValueAsString = strval($numericValue);

// Display numeric value in input field
echo '<input type="text" name="numeric_input" value="' . $numericValueAsString . '">';
