I need two functions.

1. Function that accepts input version number.  Returns true if the server MySQL version is equal to or greater than the input version.
2. Function that returns true if mod_rewrite is installed on the server.

1) check mysql version
see: http://dk2.php.net/manual/en/function.mysqli-get-server-version.php

fx:

function checkMySQL( $main, $minor, $sub ) {
    $temp = $main*10000 + $minor*100 + $sub;
    if( $temp <= mysqli-get-server-version( $mysql_conn ) ) {
        return true;
    } else {
        return false;
    }
}
// so if you require 4.1.4 or later:
if ( checkMySQL( 4, 1, 4 ) ) {
    // Yes the SQL is new enough
}

2) to see if mod_rewrite is installed.

<?php
if ( isset( $_ENV['SCRIPT_URL'] ) && isset( $_ENV['SCRIPT_URI'] ) ) {
    // Yes, this is an Apache server with mod_rewrite installed
}
// not entirely safe. environment variables with those names might be created in any
// operating system for other reasons :(
?>

I do not really see the need for this test. It is a once only test (when you place your script on the server), so why not just put a variable in your standard include file?

The point was to test the server before installing the script.  Would the extension_loaded php function work?

extension_loaded is for PHP extensions -- not Apache modules.

This should work:

$mod_rewrite = in_array('mod_rewrite', apache_get_modules());
