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 (
$result == && !file_exists($filename) && file_exists($new_filename)) {
        @
unlink($new_filename);
        echo 
"eio_rename_ok";
    } else {
        @
unlink($filename);
    }
}

eio_rename($filename$new_filenameEIO_PRI_DEFAULT"my_rename_cb"$filename);
eio_event_loop();
?>

The above example will output something similar to:

eio_rename_ok
