Question

我使用PHP上传文件，然后我想抓住它的URL，这样我就可以将它添加到数据库中。如何将新文件的URL转换为可用于通过MySQL插入的变量？

<?php
// Configuration - Your Options
  $allowed_filetypes = array('.jpg','.gif','.bmp','.png'); // These will be the types     of file that will pass the validation.
  $max_filesize = 524288; // Maximum filesize in BYTES (currently 0.5MB).
  $upload_path = './files/'; // The place the files will be uploaded to (currently a 'files' directory).

$filename = $_FILES['userfile']['name']; // Get the name of the file (including file   extension).
$ext = substr($filename, strpos($filename,'.'), strlen($filename)-1); // Get the extension from the filename.

// Check if the filetype is allowed, if not DIE and inform the user.
if(!in_array($ext,$allowed_filetypes))
  die('The file you attempted to upload is not allowed.');

// Now check the filesize, if it is too large then DIE and inform the user.
if(filesize($_FILES['userfile']['tmp_name']) > $max_filesize)
  die('The file you attempted to upload is too large.');

// Check if we can upload to the specified path, if not DIE and inform the user.
if(!is_writable($upload_path))
  die('You cannot upload to the specified directory, please CHMOD it to 777.');

// Upload the file to your specified path.
if(move_uploaded_file($_FILES['userfile']['tmp_name'],$upload_path . $filename))
     echo 'Your file upload was successful, view the file <a href="' . $upload_path . $filename . '" title="Your File">here</a>'; 
// It worked.
  else
     echo 'There was an error during the file upload.  Please try again.'; // It failed :(.

?>

Answer 1

您正在将文件移至网站上的某个位置：

move_uploaded_file($_FILES['userfile']['tmp_name'],$upload_path . $filename)

即$upload_path . $filename是您文件的相对URL。您可以添加站点网址以获取绝对网址。

Answer 2

实际上，在php上传的文件存储在一个临时的地方/目录中，以便进一步处理因此，您可以很好地获得它的现有网址，

$_FILES["file"]["tmp_name"]

这是您提供的URL，它将文件的副本存储在您的服务器位置如果要为通过php应用程序上传的文件指定默认loaction，
你可以在Php.ini文件中定义它 - ＆gt;编辑 - ＆gt; upload_tmp_dir元素到您的愿望
