目录扫描 PHP opendir
PHP扫描某个文件夹,防止死循环的思路。现在自己想到的只有两种思路
1, while 扫描下去,如果碰到目录继续while。容易死机卡住
2,层级扫描,扫描一层然后保存目录地址到记录文件。然后再从保存的记录文件中提取目录地址再扫描一层,每次只扫描一层。不过如果目录太多,还是容易死机。
有没有更好的思路?

可以用迭代器呀
示例
$ite=new RecursiveDirectoryIterator("./");$bytestotal=0;$nbfiles=0;foreach (new RecursiveIteratorIterator($ite) as $filename=>$cur) { $filesize=$cur->getSize(); $bytestotal+=$filesize; $nbfiles++; echo "$filename => $filesize\n";}$bytestotal=number_format($bytestotal);echo "Total: $nbfiles files, $bytestotal bytes\n";
Filesystem这个东西能解决你的问题吗?
