How can PHP developers use functions like explode and implode to manage input length and formatting in a guestbook application?

To manage input length and formatting in a guestbook application, PHP developers can use functions like explode and implode to split and join strings. By using explode, developers can split a string into an array based on a delimiter, allowing them to limit the length of input or format it as needed. On the other hand, implode can be used to join array elements back into a string for display or storage. 

// Example of using explode and implode to manage input length and formatting in a guestbook application

// Limit input length to 100 characters
$input = "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.";
$inputArray = explode(' ', $input);
$limitedInput = implode(' ', array_slice($inputArray, 0, 10)); // Limit to 10 words

echo $limitedInput; // Output: Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed do eiusmod

// Format input as a comma-separated list
$names = "John, Jane, Bob, Alice";
$namesArray = explode(', ', $names);
$formattedNames = implode(', ', array_map('ucfirst', $namesArray)); // Capitalize first letter of each name

echo $formattedNames; // Output: John, Jane, Bob, Alice
