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 />

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

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.

Sending mail using PHP and SMTP can be achieved through the PHPMailer library. 1) Install and configure PHPMailer, 2) Set SMTP server details, 3) Define the email content, 4) Send emails and handle errors. Use this method to ensure the reliability and security of emails.

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.
