Better Word Wrap

				
//**************************************
// Name: Better Word Wrap
// Description:This can split a string into lines separated by a new line character of your choice. You can also choose whether you want it to split words for an exact length or not split words.
// By: Matt DeKok
//
// Inputs:$text = Text to wrap
$line_length = (Default: 80)
$new_line_character = Default: <br />\n
$dont_split_words = Default: true
//
// Returns:A string with lines separated by the chosen new line character.
//
// Assumes:$text = "These lines won't necessarily be exactly the chosen length, so go ahead and trim the spaces at the beginning and end of the line.";
echo word_wrap($text, 20, '\n', false);
This will echo:
These lines won't ne
cessarily be exactly
 the chosen length, 
so go ahead and trim
 the spaces at the b
eginning and end of 
the line.
echo word_wrap($text, 20);
This will echo:
These lines won't<br />
necessarily be<br />
exactly the chosen<br />
length, so go ahead<br />
and trim the spaces<br />
at the beginning and<br />
end of the line.
