WORDWRAP(3)								 1							       WORDWRAP(3)

wordwrap - Wraps a string to a given number of characters

SYNOPSIS
       string wordwrap (string	$str, [int  $width = 75], [string  $break = "0], [bool	$cut = false])

DESCRIPTION
	Wraps a string to a given number of characters using a string break character.

PARAMETERS
	      o $str
		- The input string.

	      o $width
		- The number of characters at which the string will be wrapped.

	      o $break
		- The line is broken using the optional $break parameter.

	      o $cut
		- If the $cut is set to TRUE, the string is always wrapped at or before the specified $width. So if you have a word that is larger
		than the given width, it is broken apart. (See second example). When FALSE the function does not split the word even if the $width
		is smaller than the word width.

RETURN VALUES
	Returns the given string wrapped at the specified length.
