You can use the wordwrap() function to break a string into multiple lines.
string = string you want to break
width = maximum line length. default is 75
break = default is "\n"
cut = whether words longer than the specified width should be wrapped. default is False.
Here is an example:
$str = "China has reported the world's first case of a human infected with H10N3 avian influenza in its eastern province of Jiangsu.";
The above code will return the following output:
"China has reported the world's
first case of a human infected with
H10N3 avian influenza in its
eastern province of Jiangsu"
