PHP Manual: Wraps a string to a given number of characters

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

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

str: The input string.
width: The number of characters at which the string will be wrapped.
break: The line is broken using the optional break parameter.
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).

Returns the given string wrapped at the specified length.

Version	Description
4.0.3	The optional `cut` parameter was added.

$text = "The quick brown fox jumped over the lazy dog.";
$newtext = wordwrap($text, 20, "<br />\n");

The above example will output:
