Examples

Example #1 Yaf_Session::rewind() example

<?php
$session = Yaf_Session::getInstance();
$session->start();

$session->set("user_id", 42);
$session->set("lang", "en");

foreach ($session as $key => $value) {
    echo "$key => $value", PHP_EOL;
}

// a new foreach implicitly calls rewind() again
foreach ($session as $key => $value) {
    echo "$key => $value", PHP_EOL;
}
?>

The above example will output something similar to:

user_id => 42
lang => en
user_id => 42
lang => en
