<?php
    function int10to62($int10)
    {
        static $str62keys;
        $str62keys = array("0","1","2","3","4","5","6","7","8","9","a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z","A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z");
        $s62       = '';
        $r         = 0;
        while ($int10 != 0) {
            $r     = $int10 % 62;
            $s62   = $str62keys[$r] . $s62;
            $int10 = floor($int10 / 62);
        }
        return $s62;
    }
    
function getCodeByMid($mid)
{
    $url = '';
    for ($i = strlen($mid) - 7; $i > -7; $i -= 7) //从最后往前以7字节为一组读取mid
        {
        $offset1 = $i < 0 ? 0 : $i;
        $offset2 = $i   7;
        $num     = substr($mid, $offset1, $offset2 - $offset1);
        $num     = int10to62($num);
        $url     = $num . $url;
    }
    return $url;
}

function getNewUrl($uid,$mid)
{
    $newUrl = 'http://weibo.com/' . $uid . '/' . getCodeByMid($mid);
    return $newUrl;
}


echo getNewUrl('phpgao', '3524952365496186');
