wordwrap

(PHP 4 >= 4.0.2, PHP 5)

wordwrap — 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 column width. Defaults to 75.
break: The line is broken using the optional break parameter. Defaults to '\n'.
cut: If the cut is set to TRUE, the string is always wrapped at 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 column.

版本	说明
