Rearrange/Mask A String Contents

[JustinK101]

Hello, I need a simple way to hide/rearrange the contents of a string, and then have the ability to return the contents of the string back.

 

Basically what I need is encryption, but I don't want to use a key. I was thinking it would be nice to simply convert the string to binary. Then I could convert the binary back to a string. What is crucial is that I need to do return the same exact string that was put into the function. Thanks.

You could try:

 

$str = 'text goes here';
$encoded = base64_encode($str);
$decoded = base64_decode($encoded);

Ok, cool that seemed to work. What exactly does that function do?
