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) }
