I'm looking for a php function that will sanitize a string and make it ready to use for a filename. Anyone know of a handy one?

( I could write one, but I'm worried that I'll overlook a character! )

用于将文件保存在Windows NTFS文件系统上.

for saving files on a Windows NTFS filesystem.

推荐答案

不用担心忽略字符-如何使用您愿意使用的字符白名单?例如，您可以只允许良好的a-z，0-9，_和单个句点(.).显然，这比大多数文件系统要严格得多，但应该可以确保您的安全.

Instead of worrying about overlooking characters - how about using a whitelist of characters you are happy to be used? For example, you could allow just good ol' a-z, 0-9, _, and a single instance of a period (.). That's obviously more limiting than most filesystems, but should keep you safe.
