What are the implications of manipulating the $_FILES array in PHP, considering it is temporary and deleted after the script ends?

When manipulating the $_FILES array in PHP, it's important to remember that the uploaded files are stored in a temporary location and are deleted after the script ends. This means that any changes made to the $_FILES array will not persist beyond the current script execution. To work around this limitation, you can move the uploaded file to a permanent location on the server if you need to retain it for future use. 

// Example code to move uploaded file to a permanent location
$targetDir = "uploads/";
$targetFile = $targetDir . basename($_FILES["fileToUpload"]["name"]);

if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $targetFile)) {
    echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
} else {
    echo "Sorry, there was an error uploading your file.";
}
