Example #1 eio_lstat() example

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

function 
my_res_cb($data$result) {
    
var_dump($data);
    
var_dump($result);
}

function 
my_open_cb($data$result) {
    
eio_close($result);
    
eio_event_loop();

    @
unlink($data);
}

eio_lstat($tmp_filenameEIO_PRI_DEFAULT"my_res_cb""eio_lstat");
eio_open($tmp_filenameEIO_O_RDONLYNULL,
 
EIO_PRI_DEFAULT"my_open_cb"$tmp_filename);
eio_event_loop();
?>

The above example will output something similar to:

string(9) "eio_lstat"
array(12) {
 ["st_dev"]=>
  int(2050)
  ["st_ino"]=>
  int(2099197)
  ["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(1318235777)
  ["st_mtime"]=>
  int(1318235777)
  ["st_ctime"]=>
