Troubleshooting Move_uploaded_file() Function Malfunction

When attempting to implement user file uploads on a website, you may encounter issues with the move_uploaded_file() function. Here are the steps to diagnose and resolve the problem:

1. Enable PHP Error Reporting: Ensure that PHP error reporting is enabled to display any error messages generated by move_uploaded_file(). This will provide valuable insights into the issue.
2. Inspect the Error Code: Check the value of $_FILES'file'. Error statuses range from 0 to 8, providing information on the nature of the upload failure.

In the provided code:

• The file size is incorrect. Ensure that the file size is within the allowed limits specified by MAX_FILE_SIZE.
• The file's name is invalid. The file will be stored in a temporary location. To work with the original file name, use $_FILES'file'.

The revised code snippet for correct file upload would be:

<code class="php">move_uploaded_file($_FILES['file']['tmp_name'], $move . $_FILES['file']['name']);</code>
