如何在php中设置和获取用于文件上传的临时文件夹/文件

Question

I was using the system default temp folder (C:\\Xampp\\tmp) for file uploads. But now I need to specify a temp folder to store the temp files before upload. Is this the right function?

ini_set('upload_tmp_dir','../../tempuploads'); 

And how to get the file from there?

Till now I was using this:

$file_tmpname = $_FILES["ctrlFileUpload"]["tmp_name"];

I hope this is possible.

Answer 1

It's not temp file "before" upload but temp during and just after upload. If your ini_set works file tmp_name will be okay and you just have to use move_uploaded_file after that tu push your file in a correct f

Answer 2

You can set upload_tmp_dir in the php.ini file:
Set upload_tmp_dir to a safe location

upload_tmp_dir = /var/www/foo.bar/sessions
ini_set(‘upload_tmp_dir’, ‘/path/to/dir’);

The setting can also be applied in apache's httpd.conf file, or an .htaccess file:

# Set upload_tmp_dir to a safe location
php_value    upload_tmp_dir    /var/www/xxx.bar/sessions
