刚刚接触php,求助大家怎么在php中判断某个目录下的文件是否存在?
这个我执行有错误。麻烦大家帮看看,先谢谢各位了。
$file = ../language/$yy.php;
if (is_file($file) == false) {
require(../language/$yy.php); }
else {
require(../language/m.php); }
clearstatcache();
------解决方案--------------------
php code $filename = ../language/$yy.php;if (file_exists($filename)) { //do some thing} else { //do other thing}
