很多时候,当我们在操作过程中,调整了表结构或者需要因为特殊的原因手动清理掉某些缓存文件时,需要用到这个方法。仅限于File缓存的方式。
很多时候,当我们在操作过程中,调整了表结构或者需要因为特殊的原因手动清理掉某些缓存文件时,需要用到这个方法。仅限于File缓存的方式。
如果要删除其他的缓存也是可以的,你可以去找一下TP的系统变量,里面有其他几个缓存目录的常量。
使用方法,直接用调用cache_clear方法即可。写的比较简单,如果需要请自行扩充,另外,很多教程里说,要用到IO类来删除缓存,可惜的是TP的3.1版本之后都没看到这个类在那里。或许是我没找到。public function cache_clear() {<br>
$this->deldir(TEMP_PATH);<br>
}<br>
<br>
function deldir($dir) {<br>
$dh = opendir($dir);<br>
while ($file = readdir($dh)) {<br>
if ($file != "." && $file != "..") {<br>
$fullpath = $dir . "/" . $file;<br>
if (!is_dir($fullpath)) {<br>
unlink($fullpath);<br>
} else {<br>
deldir($fullpath);<br>
}<br>
}<br>
}<br>
}
