Codex:

Sanitizes a string and removed disallowed URL protocols.

This function removes all non-allowed protocols from the beginning of the string. It ignores whitespace and the case of the letters, and it does understand HTML entities. It does its work recursively, so it won't be fooled by a string like javascript:javascript:alert(57).
