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; }
回复讨论(解决方案)
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

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.

PHP is not dying, but constantly adapting and evolving. 1) PHP has undergone multiple version iterations since 1994 to adapt to new technology trends. 2) It is currently widely used in e-commerce, content management systems and other fields. 3) PHP8 introduces JIT compiler and other functions to improve performance and modernization. 4) Use OPcache and follow PSR-12 standards to optimize performance and code quality.

The future of PHP will be achieved by adapting to new technology trends and introducing innovative features: 1) Adapting to cloud computing, containerization and microservice architectures, supporting Docker and Kubernetes; 2) introducing JIT compilers and enumeration types to improve performance and data processing efficiency; 3) Continuously optimize performance and promote best practices.

In PHP, trait is suitable for situations where method reuse is required but not suitable for inheritance. 1) Trait allows multiplexing methods in classes to avoid multiple inheritance complexity. 2) When using trait, you need to pay attention to method conflicts, which can be resolved through the alternative and as keywords. 3) Overuse of trait should be avoided and its single responsibility should be maintained to optimize performance and improve code maintainability.

Dependency Injection Container (DIC) is a tool that manages and provides object dependencies for use in PHP projects. The main benefits of DIC include: 1. Decoupling, making components independent, and the code is easy to maintain and test; 2. Flexibility, easy to replace or modify dependencies; 3. Testability, convenient for injecting mock objects for unit testing.

SplFixedArray is a fixed-size array in PHP, suitable for scenarios where high performance and low memory usage are required. 1) It needs to specify the size when creating to avoid the overhead caused by dynamic adjustment. 2) Based on C language array, directly operates memory and fast access speed. 3) Suitable for large-scale data processing and memory-sensitive environments, but it needs to be used with caution because its size is fixed.

PHP handles file uploads through the $\_FILES variable. The methods to ensure security include: 1. Check upload errors, 2. Verify file type and size, 3. Prevent file overwriting, 4. Move files to a permanent storage location.

In JavaScript, you can use NullCoalescingOperator(??) and NullCoalescingAssignmentOperator(??=). 1.??Returns the first non-null or non-undefined operand. 2.??= Assign the variable to the value of the right operand, but only if the variable is null or undefined. These operators simplify code logic, improve readability and performance.
