# wordwrap

(PHP 4 >= 4.0.2, PHP 5)

wordwrap -- Wraps a string to a given number of characters using a string break character

## Description

string wordwrap ( string str [, int width [, string break [, bool cut]]] )

Returns a string with `str` wrapped at the column number specified by the optional `width` parameter. The line is broken using the (optional) `break` parameter.

wordwrap() will automatically wrap at column 75 and break using '`\n`' (newline) if `width` or `break` are not given.

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).

> 注意: The optional `cut` parameter was added in PHP 4.0.3

例 1. wordwrap() example

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

This example would display:

    The quick brown fox<br />
    jumped over the lazy<br />
    dog.

例 2. wordwrap() example

`<?php $text = "A very long woooooooooooord."; $newtext = wordwrap($text, 8, "\n", true); echo "$newtext\n"; ?>`

This example would display:

    A very
    long
    wooooooo
    ooooord.
