The only real option I can think of here (short of implementing all these expansions yourself) is the use of the eval command.

Problem is this opens you up to command injection. For example the filename could be $(chmod 777 /home/lessnux/.profile)

Code:
#!/bin/bash
process_files()
{
 while [ $# -gt 0 ]
 do
    echo "filename: " $1
    shift
 done
}
 
read -rp "Enter files: " files
eval process_files $files


Code:
Enter files: "Summer View.txt" Winter\ View.txt /etc/pro*
filename:  Summer View.txt
filename:  Winter View.txt
filename:  /etc/profile
filename:  /etc/protocols

LEARN ABOUT PHP

filesize

FILESIZE(3)								 1							       FILESIZE(3)

filesize - Gets file size

SYNOPSIS

       int filesize (string  $filename)

DESCRIPTION

	Gets the size for the given file.

PARAMETERS

	      o $filename
		- Path to the file.

RETURN VALUES

	Returns the size of the file in bytes, or FALSE (and generates an error of level E_WARNING) in case of an error.

       Note

	       Because PHP's integer type is signed and many platforms use 32bit integers, some filesystem functions may return unexpected results
	      for files which are larger than 2GB.

EXAMPLES

       Example #1

	      filesize(3) example

	      <?php

	      // outputs e.g.  somefile.txt: 1024 bytes

	      $filename = 'somefile.txt';
	      echo $filename . ': ' . filesize($filename) . ' bytes';

	      ?>

ERRORS
/EXCEPTIONS
	Upon failure, an E_WARNING is emitted.

NOTES

       Note

	      The results of this function are cached. See clearstatcache(3) for more details.

       Tip

	      As of PHP 5.0.0, this function can also be used with some URL wrappers. Refer to "Supported Protocols  and  Wrappers"  to  determine
	      which wrappers support stat(3) family of functionality.

SEE ALSO

       file_exists(3).
