使用php访问数组元素中字段的正确方法是什么?
I'm getting a few rows from the DB with an ajax call in PHP and I save the result to an array with javascript.
Then I make some changes in the data and wish to update the DB.
So I use another ajax call for that but I can't manage to access the fields inside the rows correctly.
When I try this I get nothing:
echo $bArray[$i].branchId;
When I try this:
echo json_encode($bArray[$i].branchId);
I get ArraybranchId
instead of the field value.
What's the correct way to access the field with php?
我从数据库中获取了几行,并在PHP中调用了ajax,并将结果保存到数组中 使用javascript。
然后我对数据进行了一些更改,并希望更新数据库。
我为此使用了另一个ajax调用,但我无法正确访问行内的字段。 br>
当我尝试这个时我什么都没得到: p>
echo $ bArray [$ i] .branchId;
code> pre>
当我尝试这个时: p>
echo json_encode($ bArray [$ i] .branchId);
code> pre>
我得到 ArraybranchId code>而不是字段值。 p>
使用php访问该字段的正确方法是什么? p>

Try either for array:
$bArray[$i]['branchId']
or for object:
$bArray[$i]->branchId
depending which type $bArray[$i]
is (array or object). You have not written in your question, so I showed both ways.
I take it branchId
is the name of the field, and you want the value
for that field?
If so, it's:
echo $bArray['branchId'];
or
echo $bArray[$i]['branchId']
Edit: Also, you'll need to make sure you're using mysql_fetch_assoc
not mysql_fetch_array
