truncate

This truncates a variable to a character length, default is 80. As an optional second parameter, you can specify a string of text to display at the end if the variable was truncated. The characters in the string are included with the original truncation length. By default, truncate will attempt to cut off at a word boundary. If you want to cut off at the exact character length, pass the optional third parameter of true.

Parameter Position	Type	Required	Default	Description
1	integer	No	80	This determines how many characters to truncate to.
2	string	No	...	This is a text string that replaces the truncated text. Its length is NOT included in the truncation length setting.
3	boolean	No	false	This determines whether or not to truncate at a word boundary (false), or at the exact character (true).
4	boolean	No	false	This determines whether the truncation happens at the end of the string (false), or in the middle of the string (true). Note that if this setting is true, then word boundaries are ignored.

Example 5-20. truncate


<?php
    
$smarty->assign('articleTitle', 'Two Sisters Reunite after Eighteen Years at Checkout Counter.');
