What considerations should be taken into account when modifying a PHP script to include more characters from a surname in a formatted output?
When modifying a PHP script to include more characters from a surname in a formatted output, you should consider the length of the surname and how much of it you want to display. You may need to adjust the formatting of the output to accommodate longer surnames and ensure that the output remains visually appealing. Additionally, you should consider how the modification may impact other parts of the script or any potential conflicts with existing code.
<?php
$surname = "Smith";
$characters_to_display = 3; // Change this value to display more characters from the surname
$formatted_output = sprintf("Hello, %s.", substr($surname, 0, $characters_to_display));
echo $formatted_output;
?>
