PHP library for normalizing URLs as specified in RFC 3986. The library doesn't require any dependencies. The library is very simple to use: simply include it and call normalizeURL() with the input URL as a str param.

Supports:

• Removal of WWW subdomains, e.g. if www.foo.bar points to the same location as foo.bar.
• Removal of default ports (HTTP and HTTPS supported by default; edit $defaultSchemes to support additional protocols and ports if you wish)
• Removal of duplicate slashes
• Decoding unreserved characters
• Removal of default directory index files
• Removal of dot segments in URL path
• Sorting GET params alphabetically
