当我打印我的Joomla会话时,我得到的数据输出就像波纹管一样.现在我想找到compare_session,并且需要使用逗号单独存储所有mtaching.我不会使用重复键表单数组.
我希望输出像这样：
281,147,136,96,46,30
Array
(
[__default] => Array
(
[session.counter] => 9
[session.timer.start] => 1376717892
[session.timer.last] => 1376718229
[session.timer.now] => 1376718247
[session.client.browser] => Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/28.0.1500.95 Safari/537.36

[compare_session_20130817111408] => 96,46,30
)
)
任何想法或建议？谢谢.
解决方法:
$sessions = array();
foreach ($mySession['__default'] as $key => $value)
{
if (preg_match("/^compare_session_(.*)$/", $key))
{
$exp = explode(",", $value);
foreach ($exp as $session)
{
if (!in_array($session, $sessions))
$sessions[] = $session;
}
}
}
var_dump($sessions);
产量
array (size=6)
0 => string '281' (length=3)
1 => string '147' (length=3)
2 => string '136' (length=3)
3 => string '96' (length=2)
4 => string '46' (length=2)
5 => string '30' (length=2)
