Empty ($ listval) {$ url = md5 ($ listval); $ cacheFile = $ cachePath. substr ($ url,-1, 1 ). '/'. substr ($ url,-3, 2 ). '/'. $ url; echo $ cacheFile; if (! File_exists ($ cacheFile) {echo 'the cache does not exist! ';} Else {if (unlink ($ cacheFile) {echo 'cache cleared successfully';} else {echo 'cache cleared failed ';}}}}
