To upload files using PHP, you can:
Configure the php.ini file to allow file uploads
Use an HTML form with a method attribute set to post and an ` enctype` attribute set to multipart/form-data
Use a `file <input> element to specify the file to upload
Use the multidimensional $_FILES array to access information about the file upload
Use the information in the $_FILES array to move the file from the temporary directory to the desired location 

When a file is uploaded, it's saved as a temporary file, and the full path to this file is in the temp name element. Once uploaded, you need to move this file to a more permanent location. The original file name is in the name element. 
Here are some other things you can do: Check if the file already exists, Limit file size, Limit file type, Access information about the uploaded files using file super global, and Check for error code constants.
