不确定指数——奇怪吗?
原标题:Undefined index - strange?

我经历的是一些不确定的指数。

$vatcode =  U25 ;
echo $this->vatcode_ids[ U25 ]."
";
echo $this->vatcode_ids[$vatcode]."
";

foreach($this->vatcode_account_ids as $id => $vatcode){
    echo $vatcode."
";
    echo $this->vatcode_ids[$vatcode]; // undefined index
}

返回:

681
681
U25  

Notice: Undefined index: U25   in /var/www/.....php on line 64

我拿不了吗?

最佳回答

从通知发布前印制的空线上,假定您的美元编码变量含有一些终结的新线特性。 如果是的话,它就不与 $子和gt子的任何钥匙相匹配;vatcode_ids range。

你们应该像Dan Lee在评论中所建议的那样,使用一些三流功能。
