Examples
Example #1 eio_symlink() example
<?php
$filename = dirname(__FILE__)."/symlink.dat";
touch($filename);
$link = dirname(__FILE__)."/symlink.link";
function my_symlink_cb($data, $result) {
global $link, $filename;
var_dump(file_exists($data) && is_link($data));
if (!eio_readlink($data, EIO_PRI_DEFAULT, "my_readlink_cb", NULL)) {
@unlink($link);
@unlink($filename);
}
}
function my_readlink_cb($data, $result) {
global $filename, $link;
var_dump($result);
@unlink($link);
@unlink($filename);
}
eio_symlink($filename, $link, EIO_PRI_DEFAULT, "my_symlink_cb", $link);
eio_event_loop();
?>
The above example will output something similar to:
bool(true) string(16) "/tmp/symlink.dat"
