What is the significance of using maxlength="3" in a text field when working with PHP forms?

Setting maxlength="3" in a text field limits the number of characters a user can input, which can be useful for fields that require a specific format or length. This can help prevent users from entering too much data, which could potentially cause issues with the form submission or database storage. By enforcing a maxlength, you can ensure that the data inputted meets the required criteria. 

<form method="post" action="process_form.php">
  <input type="text" name="code" maxlength="3">
  <input type="submit" value="Submit">
</form>
