We've seen how to implement streams and wrappers and had a hint of the new filter API in PHP 5.
You can apply this knowledge to...
- • Implement additional URL protocols (eg: LDAP)
- • Virtual Filesystem Layers by hooking opendir() and stat()
eg: transparent webdav access
- • Write reusable filters
You can do most of the above in PHP script too - we have user-space mappings for many of these features.
