STAT(3F)																  STAT(3F)

NAME

       stat, lstat, fstat - get file status

SYNOPSIS

       integer function stat (name, statb)
       character*(*) name
       integer statb(12)

       integer function lstat (name, statb)
       character*(*) name
       integer statb(12)

       integer function fstat (lunit, statb)
       integer statb(12)

DESCRIPTION

       These  routines	return	detailed  information  about a file.  Stat and lstat return information about file name; fstat returns information
       about the file associated with fortran logical unit lunit.  The order and meaning  of  the  information	returned  in  array  statb  is	as
       described for the structure stat under stat(2).	The ``spare'' values are not included.

       The value of either function will be zero if successful; an error code otherwise.

FILES

       /usr/lib/libU77.a

BUGS

       Pathnames can be no longer than MAXPATHLEN as defined in <sys/param.h>.

STAT(3) 								 1								   STAT(3)

stat - Gives information about a file

SYNOPSIS

       array stat (string  $filename)

DESCRIPTION

	Gathers  the statistics of the file named by $filename. If $filename is a symbolic link, statistics are from the file itself, not the sym-
       link.

       lstat(3) is identical to stat(3) except it would instead be based off the symlinks status.

PARAMETERS

	      o $filename
		- Path to the file.

RETURN VALUES

       stat(3) and fstat(3) result format

	* On Windows this will always be 0.

	** Only valid on systems supporting the st_blksize type - other systems (e.g. Windows) return -1.

	In case of error, stat(3) returns FALSE.

       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.

ERRORS
/EXCEPTIONS
	Upon failure, an E_WARNING is emitted.

EXAMPLES

       Example #1

	      stat(3) example

	      <?php
	      /* Get file stat */
	      $stat = stat('C:phpphp.exe');

	      /*
	       * Print file access time, this is the same
	       * as calling fileatime()
	       */
	      echo 'Access time: ' . $stat['atime'];

	      /*
	       * Print file modification time, this is the
	       * same as calling filemtime()
	       */
	      echo 'Modification time: ' . $stat['mtime'];

	      /* Print the device number */
	      echo 'Device number: ' . $stat['dev'];
	      ?>

       Example #2

	      Using stat(3) information together with touch(3)

	      <?php
	      /* Get file stat */
	      $stat = stat('C:phpphp.exe');

	      /* Did we failed to get stat information? */
	      if (!$stat) {
		  echo 'stat() call failed...';
	      } else {
		  /*
		   * We want the access time to be 1 week
		   * after the current access time.
		   */
		  $atime = $stat['atime'] + 604800;

		  /* Touch the file */
		  if (!touch('some_file.txt', time(), $atime)) {
		      echo 'Failed to touch file...';
		  } else {
		      echo 'touch() returned success...';
		  }
	      }
	      ?>

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.
