Has anyone attempted to make PHP's system functions more Object-Oriented?
<p>I'm just curious if any project exists that attempts to group all (or most) of PHP's built-in functions into a more object-oriented class hierarchy. For example, grouping all the string functions into a single String class, etc.</p>

<p>I realize this won't actually solve any problems (unless the modifications took place at the PHP source code level), since all the built-in functions would still be accessible in the global namespace, but it would certainly make usability much easier.</p>
