URL-String-concatenation within Curl-Multi: a Loop-array: [a easy one]

hello dear OpenSuse-Friends,

i have some issues with the string concatenation in PHP. i currently write a parser -

here we go - the target urls: see the overview: Bildungsserver Hessen - Schulserver
Bildungsserver Hessen - Datenbank aller Schulen in Hessen
Search by pressing the button “type” and then choose all schools with the mouse!
Results 2400 schools: Here i can provide some “more help for getting the target!” -

btw: see some details for this target-server:
Bildungsserver Hessen - Schule für Erwachsene Osthessen
Bildungsserver Hessen - Berufliche Schulen Schwalmstadt
Bildungsserver Hessen - Private Marienschule

well - you see i have to itterate over the sites - with a function /(a loop)
Bildungsserver Hessen - to 10000

BTW - after fetching the page i have to see which one are empty - those ones do not need to be parsed!

Well - i want to do this with curl-multi since this is the most advanced way to do this: I see i have ** an array** that can be filled -…
but i have to think about the string-concatenation - i guess that i have make some
sophisticated string concatenation.

this one does not fit -

 $url = "http://www.example.com/page?page={$i}";

and besides this i have an array - i c an fill the array.

can you help me how to run in a loop with
