我想知道如果有人知道如何從php中獲取隨機圖片URL? 如果得到這個代碼,但它不工作。 (錯誤顯示「搜索時出錯兩次」)Google的隨機圖片網址
<?
function GetRandomImageURL($topic='', $min=0, $max=100)
{
// get random image from Google
if ($topic=='') $topic='image';
$ofs=mt_rand($min, $max);
$geturl='http://www.google.com/images?q=' . $topic . '&start=' . $ofs . '&gbv=1';
$data=file_get_contents($geturl);
$f1='<div id="center_col">';
$f2='<a href="/imgres?imgurl=';
$f3='&imgrefurl=';
$pos1=strpos($data, $f1)+strlen($f1);
if ($pos1==FALSE) return FALSE;
$pos2=strpos($data, $f2, $pos1)+strlen($f2);
if ($pos2==FALSE) return FALSE;
$pos3=strpos($data, $f3, $pos2);
if ($pos3==FALSE) return FALSE;
return substr($data, $pos2, $pos3-$pos2);
}
function ShowRandomImage($topic='')
{
echo('<table border="1"><tr><td>');
$url=GetRandomImageURL($topic);
if ($url==FALSE) echo('Error while searching');
else {
echo(htmlentities($url) . '<br />');
echo('<img width="500" src="' . $url . '" />');
}
echo('</td></tr></table>');
}
ShowRandomImage();
#you can chage flower with any topic which you want to load image.
ShowRandomImage('flower');
?>
謝謝您的幫助和時間提前。

歡迎來到堆棧溢出。 「它不工作」是*從來不是一個好的錯誤描述。請描述出了什麼問題,出現什麼錯誤消息等。 – 2012-02-25 21:36:13
我可以推薦你實際解析HTML,而不是用可能很快變得過時的參數來分解它。 – 2012-02-25 21:41:33
閱讀錯誤日誌:'file_get_contents'不允許連接到其他主機(因爲URL前面的「http://」是被禁止的)。代碼正在爲我工作,所以編輯你的PHP配置將解決這個問題。 – Chris 2012-02-25 21:41:56
