PHP/MYSQLI:fetch_assoc()与fetch_array(MYSQLI_ASSOC) [英] PHP/MYSQLI: fetch_assoc() vs fetch_array(MYSQLI_ASSOC)

问题描述

$result->fetch_assoc()和
之间是否存在任何种类的差异 $result->fetch_array(MYSQLI_ASSOC)还是完全相同的东西?

Is there any difference of any kind between $result->fetch_assoc() and
$result->fetch_array(MYSQLI_ASSOC) or they are exactly the same thing?

在提出此问题之前，我已经进行了一些搜索，但是我发现的唯一内容(此处)是没有参数的$result->fetch_array()允许数字索引和关联索引，而
$result->fetch_assoc()仅允许关联索引，因此最后一个具有更好的性能.

I have searched a bit before making this question but the only thing I've found (here) is that $result->fetch_array() with no params allows numeric and associative indexes while
$result->fetch_assoc() only allows the associative indexes and therefore the last one has a better performance.

推荐答案

是的，目的格式和返回的格式.

Yes, purpose and returned formats.

fetch_array()具有更多的输出格式.您可以在此处 PHP手册:mysqli_result :: fetch_array .

fetch_array() has more output formats. You can see here PHP Manual : mysqli_result::fetch_array.

PHP手册:mysqli_result :: fetch_assoc()输出单一格式.
