Vfprintf - returns the data as required and writes directly to the document stream
Vprintf - displays the data as required
Vsprintf - returns the data as required, but not outputs it
Wordwrap - splits a string by a certain character length
The strtolower() function capitalizes all characters, the strtoupper() function capitalizes all characters, the ucfirst() function capitalizes the first letter of a given string, and the ucwords() function capitalizes the first letter of every English word given to a string. Ucfirst () deals only with the first character of a string, and ucwords() deals only with the first letter of each word (delimited by a space, "today! "Hi", "today.Hi" will be considered a word), and the case status of the remaining letters will not change.
