What are the considerations for uploading PHP files? in view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and easy way.

There are occasional problems in the actual implementation of PHP file upload. Below we sum up some skills and experience in solving the problem, which can be used as a reference object in the process of learning.

Assuming that the file field name in this interface is userfile, we can open a file selection window by browsing. After completing the selection, the text box will display the full path of the real file on the local machine. When upload is pressed, the file is transferred to the server's temporary directory and renamed to php?.tmp, where the question mark is a random number.

The html code for uploading PHP files is as follows:

< form action="upload.php" method="post" enctype="multipart/form-data" name="form1" >

< input type="hidden" name="MAX_FILE_SIZE" value="30000">

< input name="userfile" type="file" >

< input type="submit" name="Submit" value="上传">

< /form>

After transferring to another file, upload.php, you can access the information related to that file through the following variables

$userfile_name upload document name

Temporary name to which the userfile_tmp_name uploaded document was saved

$userfile_size upload document size (in bytes)

$mime type of userfile_type uploaded document

The variables in these PHP file uploads are fine in windows+apache, but if you can't access them under linux, you can use the following variables

$_ FILE ['userfile'] [' name'] is equivalent to $userfile_name

$_ FILE ['userfile'] [' tmp_name'] is equivalent to $userfile_tmp_name

$_ FILE ['userfile'] [' size'] is equivalent to $userfile_size

$_ FILE ['userfile'] [type] is equivalent to $userfile_type
