clearAllCache()

clears the entire template cache

Description

void

clearAllCache

int

expire_time

As an optional parameter, you can supply a minimum age in seconds the cache files must be before they will get cleared.

Note

Since Smarty version 3.1.14 it is possible to delete cache files by their individual expiration time at creation by passing constant SMARTY::CLEAR_EXPIRED as expire_time parameter.

<?php
// clear the entire cache
$smarty->clearAllCache();

// clears all files over one hour old
$smarty->clearAllCache(3600);
?>

See also clearCache(), isCached() and the caching page.
