hello dear community
I am trying to figure out a method how to retrieve on the same URLs [see below] with different query arguments, and i am wondering if this is doable with PHP!?
on a sidenote: Well - i guess that we can do this with LWP::UserAgent - guess that this provides a way for us to loop through the query arguments: I am not sure that LWP::UserAgent has a method for us to do that. I tried to figure it out. And i digged deeper in the Manpages and Howtos. we can have a loop constructing the URLs and use LWP::UserAgent repeatedly:
for my $id (0 .. 100000)
{
$ua->get($url."?id=21&extern_eid=".(0-$id))
//rest of the code
}
Well, alternatively we can add a request_prepare handler that computes and add the query arguments before we send out the request. Do you think that this fits the needs?
But wait - i want to do this with PHP!
What is aimed: Here on this following site we find a list of many schools: see the page with the subsequent results - approx more than 1000 sites
i want to fetch the sites that are listet on this page - and therefore i want to use PHP for this job - and subesquently i want to parse them.
the sites can be reached directly - by constructing
in other words the subsites of the overview can be reached via direct links... see the following.

Well - i want to fetch all those.... And i try to do it with PHP and a mentioned loop. Does this work!? 🙂
