file_get_contents把类似file:///文件移到服务器上

本帖最后由 molaifeng 于 2013-12-12 17:39:38 编辑使用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 />

PHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

PHP Performance: Identifying and Fixing BottlenecksMay 11, 2025 am 12:13 AM

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
