move_uploaded_file() in PHP

Description

The move_uploaded_file() is a PHP function that is used to move an uploaded file to a new destination.

Notes:

Before moving the uploaded file to a new location, this function first checks if the file is a valid upload or not (i.e. uploaded using HTTP POST mechanism).
Therefore we can say this function only works if the file is uploaded using HTTP POST mechanism.
If the desitnation file already exists, it will be overwritten.
This function works with PHP version 4.0.3 and above.

Parameter
