php数据库两个关联大表的大数组分页处理,防止内存溢出

        $ret = self::$db->select($tables, $fields, $where, $bind);

        if (!empty($ret)) {
$retIds = array();
$ids = array();
while (!empty($ret)) {
$_sub = array_splice($ret, 0, 10000); //每次取出10000个
foreach ($_sub as $v) {
array_push($retIds, $v['pt_AccountKey']);
}
unset($_sub);
/*过滤非快速登陆类型*/
$place_holders = implode(',', array_fill(0, count($retIds), '?'));
array_unshift($retIds, 'autoregs');
$PT_Account = self::$db->select('PT_Account', 'pt_AccountKey', 'pt_RegisteSource=? AND pt_AccountKey IN (' . $place_holders . ')', $retIds);
if (!empty($PT_Account)) {
array_push($ids, $v['pt_AccountKey']);
} }
unset($ret); if (!empty($ids)) {
$num = count($ids);
$_sub = array_splice($ids, $get['start'], $get['limit']);
$place_holders = implode(',', array_fill(0, count($_sub), '?'));
$where = 'pt_AccountKey IN (' . $place_holders . ')';
$list = self::$db->select('PT_Account', 'pt_AccountID,pt_Password', $where, $_sub);
$grid = array();
$grid['rows'] = $list;
$grid['total'] = $num;
return $grid;
}
}
