wordwrap
行寬約束

Parameter Position Type Required Default Description
1 integer No 80 This determines how many columns to wrap to.
指定段落(句子)的寬度
2 string No \n This is the string used to wrap words with.
使用什么字符約束
3 boolean No false This determines whether or not to wrap at a word boundary (false), or at the exact character (true).
是約束到詞的邊界（假）還是精確到字符（真）

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.

可以指定段落的寬度(也就是多少個(gè)字符一行,超過(guò)這個(gè)字符數(shù)換行).默認(rèn)80.
第二個(gè)參數(shù)可選,可以指定在約束點(diǎn)使用什么字符(默認(rèn)是換行符\n).
默認(rèn)情況下smarty將截取到詞尾,如果想精確到設(shè)定長(zhǎng)度的字符，請(qǐng)將第三個(gè)參數(shù)設(shè)為ture

Example 5-23. wordwrap
例 5-23.行寬約束 

index.php:

$smarty = new Smarty;
$smarty->assign('articleTitle', "Blind woman gets new kidney from dad she hasn't seen in years.");
$smarty->display('index.tpl');

index.tpl:

{$articleTitle}

{$articleTitle|wordwrap:30}

{$articleTitle|wordwrap:20}

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

{$articleTitle|wordwrap:30:"\n":true}

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
kidney from dad she
hasn't seen in
years.

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

Blind woman gets new kidney fr
om dad she hasn't seen in year
