Example #1 eio_statvfs() example
<?php
$tmp_filename = '/tmp/eio-file.tmp';
touch($tmp_filename);
function my_statvfs_callback($data, $result) {
var_dump($data);
var_dump($result);
@unlink($data);
}
eio_statvfs($tmp_filename, EIO_PRI_DEFAULT, "my_statvfs_callback", $tmp_filename);
eio_event_loop();
?>The above example will output something similar to:
string(17) "/tmp/eio-file.tmp"
