)

Parameters

Examples

Example #1 eio_stat example

<?php
$tmp_filename = "eio-file.tmp";
touch($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_stat($tmp_filename, EIO_PRI_DEFAULT, "my_res_cb", "eio_stat");
eio_open($tmp_filename, EIO_O_RDONLY, NULL,
 EIO_PRI_DEFAULT, "my_open_cb", $tmp_filename);
eio_event_loop();
?>

The above example will output something similar to:

string(8) "eio_stat"
array(12) {
  ["st_dev"]=>
  int(2050)
  ["st_ino"]=>
  int(2489173)
  ["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(1318250380)
  ["st_mtime"]=>
  int(1318250380)
  ["st_ctime"]=>
  int(1318250380)
}
