Example #1 eio_rename() example
<?php
$filename = dirname(__FILE__)."/eio-temp-file.dat";
touch($filename);
$new_filename = dirname(__FILE__)."/eio-temp-file-new.dat";
function my_rename_cb($data, $result) {
global $filename, $new_filename;
if ($result == 0 && !file_exists($filename) && file_exists($new_filename)) {
@unlink($new_filename);
echo "eio_rename_ok";
} else {
@unlink($filename);
}
}
eio_rename($filename, $new_filename, EIO_PRI_DEFAULT, "my_rename_cb", $filename);
eio_event_loop();
?>
The above example will output something similar to:
eio_rename_ok
