我要检查对指数
解决方案
$ ARR = array_filter（$ ARR，功能（$项目）
{
如果（使用isset（$本期特价货品＆GT;！管理员）|| is_array（$本期特价货品＆GT;！管理员））
{
返回false;
}
的foreach（$本期特价货品＆GT;管理员为$管理员）
{
如果（$管理 - ＆GT;成员== 11）
{
返回true;
}
}
返回false;
}）;
（PHP 5.3中使用匿名函数）
I've got an array of objects as follows ; how can I filter out (remove) the objects that have admins->member = 11 ?
In this example, the resulting array object would only have the 1st object that [245] at the start.

I'd like to check against the index
解决方案
$arr = array_filter($arr, function($item)
{
if(!isset($item->admins) || !is_array($item->admins))
{
return false;
}
foreach($item->admins as $admin)
{
if($admin->member == 11)
{
return true;
}
}
return false;
});
