Having PHP handle static files, such as JS and CSS and gzipping them on the fly is inefficient.

A better approach is to have PHP write a gzipped version of the static file to the filesystem.

This it the embed code for that particular page:

To explain how this is done:

First you make a http request to the page you want to parse.

eg:

$url = 'http://example.com/';
$content = file_get_contents($url);

CRC32 should NOT be used at all. Not as the last hash output, or before you hash it again with a secure hash. Just not at all.

Are you using ob_start() before any PHP code?

Looks great. I modified the class I wrote a bit after looking at your code.

Just a few suggestions:

You could optimize the string concatenation.

Thought I'd write an example:

note: for PHP4 just remove the "public static" in front of each function declaration.

The class:

There really is no reason to use 2 way encryption on passwords. Retrieving the password is not the concern, gaining access to their account is. So if the user forgets their password, send them a...

Sorry for resurrecting an old thread. But it was referenced recently and I thought I'd add to it.

crc32b should not be used with passwords as it is an insecure hash function. ...

str_replace() will remove *all* occurrence of whitespace.

$str = str_replace(' ', '', $str);

Regular expressions are quite simple.

Instead of matching exact characters like in your str_replace() you match patterns.

The pattern is held in two delimiters, denoting the start and end of...
