PHP Interview Questions and Answers

How To Get the Uploaded File Information in the Receiving Script?
Once the Web server received the uploaded file, it will call the PHP script specified in the
form action attribute to process them. This receiving PHP script can get the uploaded file information
through the predefined array called $_FILES. Uploaded file information is organized in $_FILES as
a two-dimensional array as:
- $_FILES[$fieldName]['name'] - The Original file name on the browser system.
- $_FILES[$fieldName]['type'] - The file type determined by the browser.
- $_FILES[$fieldName]['size'] - The Number of bytes of the file content.
- $_FILES[$fieldName]['tmp_name'] - The temporary filename of the file in which the uploaded file was stored on the server.
- $_FILES[$fieldName]['error'] - The error code associated with this file upload.
The $fieldName is the name used in the <INPUT TYPE=FILE, NAME=fieldName>.
