file_get_contents把类似file:///文件移到服务器上

    使用ckeditor编辑器复制word文件里的图片,查看图片地址源码皆为file:///这种形式,后来便写了一个方法,在粘贴的时候注册个事件,用正则匹配类似的图片地址,再异步传到php脚本文件处理,处理方法逻辑为,使用file_get_contents读到图片地址,再使用file_put_contents写入指定目录,由于是在本地测试,没问题。svn到服务器,测试了下,发现图片都是0kb大小,后来使用is_file做测试,打印false,而在本地则是true,是不是file_get_contents在服务器读不到本地的图片。

    // 将用户从word文档里粘贴过来的图像先存到本地目录,再改变其地址返回过去    public function tranPic() {        // 检测        $_POST = unflip($_POST);        $content = strval($_POST['html']);        if (!$content) {            echo '';            exit;        }        // 图片存放域名        $imgPath = C('TMPL_PARSE_STRING');        // 图片转存后的路径        $pre = '../Uploads/';        $pic = 'Ueditor/' . date('Ymd', time()) . '/';        mk_dir($pre . $pic);        // 正则提取图片        $pattern = "/<[img|IMG].*?src=[\'|\"](.*?(?:[\.gif|\.jpeg|\.jpg|\.bmp|\.bnp|\.png|\.GIF|\.JPG|\.BMP|\.BNP|\.PNG|\.JPEG]))[\'|\"].*?[\/]?>/";        preg_match_all($pattern, $content, $match);        // 把图片地址替换为本项目中的地址        foreach ($match as $key => &$value) {            if ($key > 0) {                continue;            }            foreach ($value as $k => $v) {                // 获取图片后缀,主要图片的前五个字符是file:                if (substr($match[1][$k], 0, 5) == 'file:') {                    $ext = pathinfo($match[1][$k], PATHINFO_EXTENSION);                    $data = file_get_contents($match[1][$k]);                    $filename = uniqid() . '.' . $ext;                    file_put_contents($pre . $pic . $filename, $data);                    $content = str_replace($v, str_replace($match[1][$k], $imgPath['../Uploads/'] . $pic . $filename, $v), $content);                }            }        }        echo $content;    }
Copy after login

是的, file_get_contents在服务器读不到本地的图片
但你可以考虑经本地服务器中转

那,请问如果经本地服务器中转,给个思路,或是还有什么其他的方法!!!

我换了一种方法,使用php中的curl的post上传文件,发现还是上传不了,错误返回码为26

ajax  post提交试试

没用的,最后发现在服务器上php读不到file://开头的文件

刚刚又调了下,发现在服务器上压根就读不到本地的图片,看来此方法不行,有什么更好的方法么

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Apr 17, 2025 am 12:06 AM

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values ​​to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
