file_get_contents把类似file:///文件移到服务器上,该如何处理
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。
<br /> // 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<br /> public function tranPic() {<br /><br /> // 检测<br /> $_POST = unflip($_POST);<br /> $content = strval($_POST['html']);<br /> if (!$content) {<br /> echo '';<br /> exit;<br /> }<br /><br /> // 图片存放域名<br /> $imgPath = C('TMPL_PARSE_STRING');<br /><br /> // 图片转存后的路径<br /> $pre = '../Uploads/';<br /> $pic = 'Ueditor/' . date('Ymd', time()) . '/';<br /> mk_dir($pre . $pic);<br /><br /> // 正则提取图片<br /> $pattern = "/<[img|IMG].*?src=[\'|\"](.*?(?:[\.gif|\.jpeg|\.jpg|\.bmp|\.bnp|\.png|\.GIF|\.JPG|\.BMP|\.BNP|\.PNG|\.JPEG]))[\'|\"].*?[\/]?>/";<br /> preg_match_all($pattern, $content, $match);<br /><br /> // 把图片地址替换为本项目中的地址<br /> foreach ($match as $key => &$value) {<br /><br /> if ($key > 0) {<br /> continue;<br /> }<br /><br /> foreach ($value as $k => $v) {<br /><br /> // 获取图片后缀,主要图片的前五个字符是file:<br /> if (substr($match[1][$k], 0, 5) == 'file:') {<br /> $ext = pathinfo($match[1][$k], PATHINFO_EXTENSION);<br /> $data = file_get_contents($match[1][$k]);<br /> $filename = uniqid() . '.' . $ext;<br /> file_put_contents($pre . $pic . $filename, $data);<br /> $content = str_replace($v, str_replace($match[1][$k], $imgPath['../Uploads/'] . $pic . $filename, $v), $content);<br /> }<br /> }<br /> }<br /><br /> echo $content;<br /> }<br />
