In PHP, use basename() to strip out directory paths, leaving only the filename.
Tools like grep :

A successful path traversal attack can have severe consequences for an organization:
Some poorly designed sanitization filters simply strip out ../ globally from the input. Attackers bypass this by nesting the sequences (e.g., ....// or ...-2F-2F ). When the filter removes the inner sequence, the surrounding characters collapse together to form a perfectly valid traversal command. Risks and Impact of Successful Exploitation
