PHP将临时文件移动/复制到新目录并重命名（性能）

Question

i simply upload file from a html form.

Now , once the file is uploaded php creates a temp file somewhere.

I was wondering, is it faster to copy or move the file into a new directory?

I saw these three methods available ssh2_scp_send() copy() move_uploaded_file(); , can someone explain differences between these methods and which is faster at the end?

For each method i will go for using, i will need to rename the file anyway so the combination is copy or move + rename file.

At the end, is here a really faster solution, to move or copy file from a dir to another and rename it?

thank you

Answer 1

Use move_uploaded_file() its the most simple method to move an uploaded file to its proper destination.

In general a file move is much faster than file copy (in the same partition) because with move there is no actual file data being moved, only the fat is updated.

Answer 2

Move would be as faster than copy...

To move a file use the rename function.

To move an uploaded file move_uploaded_file is the way to go. It has a little overhead in that it check and ensures that the file was in fact the result of an upload.
