A php tag needs to be nested with one label, but both labels are nested with foreach?

The result is: 1. the first tag 2. the second tag 3. the third tag. how can php be nested together? Php $ p ):? & Gt; get the php content of Tag a, but the key value is not an ordered number & lt ;? Phpecho $ snapshot-php

The result is as follows:

1First tag2Second tag3Third tag

How can php be nested together?

// This is the php code with the serial number. $ P):?> // Obtain the php code of Tag a, but the key value is not an ordered number. Summary;?>

If I write the first php code into the tag, it will loop through the tag five times,
It's not the expected dom structure. I don't know how to nest it. it's a headache.
