How can i get the content of uploaded file in php?
提问by eagle
I can upload a file by using html file type and then I store that file information to mysql db. Here's my code=>
我可以使用 html 文件类型上传文件，然后将该文件信息存储到 mysql db。这是我的代码=>
$upload = wp_upload_bits($_FILES["upload_file"]["name"], null, file_get_contents($_FILES["upload_file"]["tmp_name"]));
$document_name = $_FILES['upload_file']['name'];
$document_link = $upload['url'];
//and DB Operations in here..(I store to db filename,date,filelink etc.)
My problem is, I can't read the file content to store it to db. (I will do search on the file content, so I must read content of file.) Briefly how can i read the content of a file like pdf, doc or etc. from url such as http://...../uploads/exampleFile.docx?
我的问题是，我无法读取文件内容以将其存储到 db。（我将对文件内容进行搜索，所以我必须阅读文件的内容。）简单地说，我如何从http://...../等网址读取 pdf、doc 等文件的内容上传/exampleFile.docx？

$fileContent = file_get_contents($_FILES['upload_file']['tmp_name']);
Refer to the manual: $_FILESfor an overview and this tutorial: Tizag PHP - File Uploadfor a walkthrough.
请参阅手册：$_FILES概述和本教程：Tizag PHP - 文件上传进行演练。
This PHP Manual section is a must-read as well: Handling File Uploads- moved from hakre's comment.
这个 PHP 手册部分也是必读的：处理文件上传- 从 hakre 的评论中移出。
