touch - Sets access and modification time of file

SYNOPSIS

       bool touch (string  $filename, [int  $time = time()], [int  $atime])

DESCRIPTION

	Attempts  to set the access and modification times of the file named in the $filename parameter to the value given in $time. Note that the
       access time is always modified, regardless of the number of parameters.

	If the file does not exist, it will be created.

PARAMETERS

	      o $filename
		- The name of the file being touched.

	      o $time
		- The touch time. If $time is not supplied, the current system time is used.

	      o $atime
		- If present, the access time of the given filename is set to the value of $atime. Otherwise, it is set to the value passed to the
		$time parameter. If neither are present, the current system time is used.

	      $time = time() - 3600;

	      // Touch the file
	      if (!touch('some_file.txt', $time)) {
		  echo 'Whoops, something went wrong...';
	      } else {
