这段PHP本来是把titlepic里的外链图片自动下载,我想让它在下载时自动缩略成固定大小的图片。求教应该怎么修改呢?
$sqltext="SELECT id,titlepic FROM {$dbtbpre}_article where titlepic like 'http://%' order by id limit 1";
$r=$empire->fetch1($sqltext);
if($r)
{
$path=ECMS_PATH."uploads\\pic\\";
$yname=$path.basename($r[titlepic]);
$filename='/uploads/pic/'.basename($r[titlepic]);
if(file_exists($yname)&&filesize($yname)>0)
{
echo($yname."已存在<br>"); //文件存在
//exit('s:'.filesize($yname));
}
else
{
echo($yname."<br>down:".$r[titlepic]);
$string=ReadFiletext($r[titlepic]);
WriteFiletext_n($yname,$string);
sleep(1);
}
$sqltext="update {$dbtbpre}_article set titlepic='$filename' where id='$r[id]'";
echo('<br>'.$sqltext);
$empire->query($sqltext);
sleep(1);
echo"<meta http-equiv=\"refresh\" content=\"1;url=?act\">";
}
else
{
//echo"<meta http-equiv=\"refresh\" content=\"1;url=ListAllInfo.php\">";
echo"完成";
}
db_close();
$empire=null;

这不是帝国CMS么,你的需求应该是把远程图片保存下来的同时自动等比例裁剪,那就写个函数加到WriteFiletext_n里面就行了。至于怎么裁剪图片谷歌一下,可以直接用imagecopyresampled,或者安装了ImageMagick更好,这个比GD类库好使。
