regex\_replace {#language.modifier.regex.replace}
|
|
==============
|
|
|
|
A regular expression search and replace on a variable. Use the
|
|
[`preg_replace()`](&url.php-manual;preg_replace) syntax from the PHP
|
|
manual.
|
|
|
|
> **Note**
|
|
>
|
|
> Although Smarty supplies this regex convenience modifier, it is
|
|
> usually better to apply regular expressions in PHP, either via custom
|
|
> functions or modifiers. Regular expressions are considered application
|
|
> code and are not part of presentation logic.
