PHP：如何遍历具有顺序名称的属性

Question

If I have a table with columns called image1, image2, image3, etc and I pulled those in an object-oriented manner, like this:

$images->image1
$images->image2
$images->image3

etc.

Is there any way to process these in a loop? Something like:

for (i=1; i<count($images); $i++) {
    $array[$i] = $images->image?
}

I realize the above won't work, but was wondering if someone could tell me a way that will work. Thanks.

Answer 1

Pulling them from the DB in an array might be a better option, but you can do it with objects by using variable variables :

for ($i = 1; i < $length; $i++) {
    $array[] = $images->{'image' . $i};
}

Answer 2

You should use an array instead.

However, you can also use variable variables for this madder.

Answer 3

for ($i = 1; i < $len; $i++) {
    $array[] = $images->{'image' + $i};
}
