Relative date

This function takes a time and returns a relative date string (it does, however, ignore the time of day). For instance: "yesterday", "in 2 days", "1 day ago", "March 12", or "May 5, 1992".

function relative_date($time) {
    $today = strtotime(date('M j, Y'));
    $reldays = ($time - $today)/86400;
    if ($reldays >= 0 && $reldays < 1) {
        return 'today';
    } else if ($reldays >= 1 && $reldays < 2) {
        return 'tomorrow';
    } else if ($reldays >= -1 && $reldays < 0) {
        return 'yesterday';
    }
    if (abs($reldays) < 7) {
        if ($reldays > 0) {
            $reldays = floor($reldays);
            return 'in ' . $reldays . ' day' . ($reldays != 1 ? 's' : '');
        } else {
            $reldays = abs(floor($reldays));
            return $reldays . ' day'  . ($reldays != 1 ? 's' : '') . ' ago';
        }
    }
    if (abs($reldays) < 182) {
        return date('l, F j',$time ? $time : time());
    } else {
        return date('l, F j, Y',$time ? $time : time());
    }
}

Canonical path

This function transforms an HTTP request path (ie, $_SERVER['PATH_INFO']) into its canonical form, removing empty path elements and relative path elements (//, /./, /../). It assumes that there is a trailing slash on the path if it's a directory.

function canonical_path($path) {
    $canonical = preg_replace('|/\.?(?=/)|','',$path);
    while (($collapsed = preg_replace('|/[^/]+/\.\./|','/',$canonical,1)) !== $canonical) {
        $canonical = $collapsed;
    }
    $canonical = preg_replace('|^/\.\./|','/',$canonical);
    return $canonical;
}
