我只接受正则表达式数组，以便处理文件名

$data = preg_replace_callback("/.+\/(.+)(\?.+)?$/", create_function('$matches', '$tmp = pathinfo($matches[1]); return $tmp["filename"];'), $i);

我只保留文件名，然后尝试通过file_put_contents保存文件。

foreach($my_img as $i){
    $tUrl = $i;


    $data = preg_replace_callback("/.+\/(.+)(\?.+)?$/", create_function('$matches', '$tmp = pathinfo($matches[1]); return $tmp["filename"];'), $i);

    $rUrl = "http://blogimgs.naver.com"; //Referer 
    $ch = curl_init(); 
    curl_setopt($ch, CURLOPT_URL, $tUrl);
    curl_setopt($ch, CURLOPT_REFERER, $rUrl);
    curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 2.0.50727; .NET CLR 1.1.4322; .NET CLR 3.0.04506.30) ');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
    curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
    curl_setopt($ch, CURLOPT_HEADER, false);
    $get = curl_exec($ch);

    curl_close($ch);

    foreach($data as $v)
    {
        file_put_contents('./blog_img/'.$v.'.jpg', $get);
    }
}

创建了0字节文件，但这将是。

我想知道发生了什么事，因为。

将正则表达式更改为：

/.+\/(.+?)(\?.+)?$/

您需要使用非贪婪的重复运算符，因为下一个组（查询字符串）是可选的。使用贪婪的量词，.+将继续结束，因为它不允许任何内容与可选组匹配。

但将正则表达式替换为parse_url：

可能会更好

$parsed = parse_url($i[1]);
$info = pathinfo($parsed['path']);
$data = $info['filename'];
