由于微博中有字数限制,所以如果你发的是网址,会自动将其变为短网址。这里我们把短网址还原为实际网址。请参照下面的程序,用PHP将微博短地址还原为实际网址方法实现:

<?php
$url= " http://163.fm/1QLJ8U";
echounshorten($url);
functionunshorten($url)
{
    $url= trim($url);
    $headers= get_headers($url);
    $location= $url;
    $short= false;
    foreach($headersas$head)
    {
        if($head=="HTTP/1.1 302 Found")
            $short= true;
        if($short&& startwith($head,"Location: "))
        {
            $location= substr($head,10);
        }
    }
    return$location;
}
functionstartwith($Haystack, $Needle)
{
    returnstrpos($Haystack, $Needle) === 0;
}
?>
Copy after login

程序运行结果如下:
