PHP SmartyPants / classic version

The classic version of PHP SmartyPants & Typographer is a hybrid library, plugin for Wordpress and for Smarty. It works with PHP 4.0.5 or later. This version is no longer supported.

If you’re a developer using PHP 5.3 or later, you should probably use PHP SmartyPants Lib instead.

PHP SmartyPants is a port to PHP of the original SmartyPants written in Perl by John Gruber.

PHP SmartyPants is a free web publishing tool that translates plain ASCII punctuation characters into “smart” typographic punctuation HTML entities.

SmartyPants can perform the following transformations:

SmartyPants does not modify characters within <pre>, <code>, <kbd>, or <script> tag blocks. Typically, these tags are used to display text where smart quotes and other “smart punctuation” would not be appropriate, such as source code or example markup.

For more details, read the SmartyPants home page.


PHP 4.0.5 or later



PHP SmartyPants works with WordPress, version 1.2 or later.

WordPress already includes a filter called “Texturize” with the same goal as SmartyPants. You could still find some usefulness to PHP SmartyPants if you are not happy enough with the standard algorithm.

To use PHP SmartyPants with WordPress, place the “smartypants.php” file in the “plugins” folder. This folder is hidden inside “wp-content” at the root of your site:

(site home)/wp-content/plugins/smartypants.php

Activate the plugin with the administrative interface of WordPress. In the “Plugins” section you will now find SmartyPants. To activate the plugin, click on the “Activate” button on the same line than SmartyPants. Your entries will now be filtered by PHP SmartyPants.

Note: It is not possible at this time to apply a different set of filters to different entries. All your entries will be filtered by PHP SmartyPants if the plugin is active.

In your programs

You can use PHP SmartyPants easily in your current PHP program. Simply include the file and then call the SmartyPants function on the text you want to convert:

include_once "smartypants.php";
$my_text = SmartyPants($my_text);

With Smarty

If your program use the Smarty template engine, PHP SmartyPants can now be used as a modifier for your templates. Rename “smartypants.php” to “modifier.smartypants.php” and put it in your smarty plugins folder.
