If I use sticky bit, wouldn't that not allow my script to delete the temp file when he runs it? Since he is not the owner of my script.
If I need to allow him to run my script from within my directory, would giving him read, write, and executable allow the temp file to be created and deleted when he runs the script? I want to make sure my script runs exactly as I intend it to and not glitch up because the temp file cannot be created when it comes to the point in my script where I resave the sorted data. That is why I asked the question in OP. If I can temporarily store the data correctly in a variable and then re-set it to the original file, I wouldn't have to worry about using a temp file. Thanks for your replies.

TMPFILE(3) 1 TMPFILE(3)
tmpfile - Creates a temporary file
SYNOPSIS
resource tmpfile (void )
DESCRIPTION
Creates a temporary file with a unique name in read-write (w+) mode and returns a file handle .
The file is automatically removed when closed (for example, by calling fclose(3), or when there are no remaining references to the file
handle returned by tmpfile(3)), or when the script ends.
For details, consult your system documentation on the tmpfile(3) function, as well as the stdio.h header file.
RETURN VALUES
Returns a file handle, similar to the one returned by fopen(3), for the new file or FALSE on failure.
EXAMPLES
Example #1
tmpfile(3) example
<?php
$temp = tmpfile();
fwrite($temp, "writing to tempfile");
fseek($temp, 0);
echo fread($temp, 1024);
fclose($temp); // this removes the file
?>
The above example will output:
writing to tempfile
