Beispiel #1 eio_lstat() example

<?php
// Create temporary file
$tmp_filename = dirname(__FILE__) ."/eio-file.tmp";
touch($tmp_filename);

/* Is called when eio_fstat() done */
function my_res_cb($data, $result) {
// Should output array with stat info
var_dump($result);

if (
$data['fd']) {
// Close temporary file
eio_close($data['fd']);
eio_event_loop();
}
// Remove temporary file
@unlink($data['file']);
}

/* Is called when eio_open() done */
function my_open_cb($data, $result) {
// Prepare data for callback
$d = array(
'fd' => $result,
'file'=> $data
);
// Request stat info
eio_fstat($result, EIO_PRI_DEFAULT, "my_res_cb", $d);
// Process request(s)
eio_event_loop();
}

// Open temporary file
eio_open($tmp_filename, EIO_O_RDONLY, NULL, EIO_PRI_DEFAULT,
"my_open_cb", $tmp_filename);
eio_event_loop();
?>

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

array(12) {
 ["st_dev"]=>
  int(2050)
  ["st_ino"]=>
  int(2489159)
  ["st_mode"]=>
  int(33188)
  ["st_nlink"]=>
  int(1)
  ["st_uid"]=>
  int(1000)
  ["st_gid"]=>
  int(100)
  ["st_rdev"]=>
  int(0)
  ["st_blksize"]=>
  int(4096)
  ["st_blocks"]=>
  int(0)
  ["st_atime"]=>
  int(1318239506)
  ["st_mtime"]=>
  int(1318239506)
  ["st_ctime"]=>
  int(1318239506)
}
