[code] Automatic File Input
i have got many files like this in my folder temp(say)
imp_02042008.txt for date 02-04-2008
imp_03092009.txt for date 03-09-2009
imp_25112009.txt for date 25-11-2009
...................
........
in some folder.
and one of my shell code uses one of the above files based on date.
for example for todays date it should pick the file imp_25112009.txt
for tomorrows date it should pick the file like imp_26112009.txt
My code is like below one:
print substr($1,4,3),"",substr($2,22,8) inputfile.txt>outputfile.txt

This code should run on day to day basis.
What i want is a code to pick up the file (eg..imp_26112009.txt) automatically from folder temp based on day.. i.e, for a given day particular file should be taken as input in my code...
pls help me in this regard..

FILEMTIME(3)								 1							      FILEMTIME(3)

filemtime - Gets file modification time

SYNOPSIS

       int filemtime (string  $filename)

DESCRIPTION

	This  function	returns  the time when the data blocks of a file were being written to, that is, the time when the content of the file was
       changed.

PARAMETERS

	      o $filename
		- Path to the file.

RETURN VALUES

	Returns the time the file was last modified, or FALSE on failure. The time is returned as a Unix timestamp,  which  is	suitable  for  the
       date(3) function.

EXAMPLES

       Example #1

	      filemtime(3) example

	      <?php
	      // outputs e.g.  somefile.txt was last modified: December 29 2002 22:16:23.

	      $filename = 'somefile.txt';
	      if (file_exists($filename)) {
		  echo "$filename was last modified: " . date ("F d Y H:i:s.", filemtime($filename));
	      }
	      ?>

ERRORS
/EXCEPTIONS
	Upon failure, an E_WARNING is emitted.

NOTES

       Note

	      Note that time resolution may differ from one file system to another.

       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.
