# wordwrap

Parameter Position | Type | Required | Default | Description
--- | --- | --- | --- | ---
1 | integer | No | 80 | This determines how many columns to wrap to.
2 | string | No | \n | This is the string used to wrap words with.
3 | boolean | No | false | This determines whether or not to wrap at a word boundary (false), or at the exact character (true).

This wraps a string to a column width, default is 80. As an optional second parameter, you can specify a string of text to wrap the text to the next line (default is carriage return \n). By default, wordwrap will attempt to wrap at a word boundary. If you want to cut off at the exact character length, pass the optional third parameter of true.

Example 5-22. wordwrap
`<?php $smarty = new Smarty; $smarty->assign('articleTitle', "Blind woman gets new kidney from dad she hasn't seen in years."); $smarty->display('index.tpl'); ?>`
where index.tpl is:
    {$articleTitle}

    {$articleTitle|wordwrap:30}

    {$articleTitle|wordwrap:20}

    {$articleTitle|wordwrap:30:"<br />\n"}

    {$articleTitle|wordwrap:30:"\n":true}
This will output:
    Blind woman gets new kidney from dad she hasn't seen in years.

    Blind woman gets new kidney
    from dad she hasn't seen in
    years.

    Blind woman gets new

    from dad she hasn't seen in<br />
    years.
