PHP, how do I output the the contents created by another php file to file?

Question

I'm trying to reduce the overhead on our database server. I use a php script to produce sitemaps of all the pages on out site, 80,000.

I want to create a cron job which will run once a week and create static versions of the php sitemap files.

However, I need to loop around and call the sitemap php script and output the contents to a separate file.

How do I output the contents of another php to a file for a cron job ?

EDIT: I'll also need to wait or sleep a while so I don't bring down the server.

EDIT for Arvin for the flow of the PHP script etc

At the moment I have a sitemap.xml file which is a sitemap index file, which has lot of www.mydomain.com/sitemap.php?start=500&max=500

The sitemap.php take between 1 second and 2 seconds to run and I have a lot of them.

What I'd like to do in a new script is ...

New script

-loop from N = 0 to 100

--output sitemap.php&start=N&max=500

--wait 20 seconds

-end loop

php script.php > anotherfile.txt

Or

wget -O- http://yoursite/script.php -o/dev/null > anotherfile.txt

I would prefer wget too because it can mirror whole sites. But there's also a programmatic way:

copy("http://localhost/sitemap.php", "/tmp/sitemap.html");

One problem I didn't think of, see my edit, I'll need to wait / sleep after each so I don't bring down the server.

For your updated details:

for($n=0; $n <= 100; $n++) {
   $output = file_get_contents("http://domain.com/sitemap.php?start={$n}&max=500");
   file_put_contents($file, $output);
   sleep(20);
}

@Jules can you add the flow of the program?

Jules Over a year ago

@arvin, I don't understand what you mean ?

@Jules 'Cause you said, sleep/wait is needed so I'm wondering. If you could list the things that the program will do. or how sitemaps, are generated. I'm guessing that one script generates 1 sitemap, and you got a bunch of these script. Are you trying to make one single script that will run the other one by one? And you mean to sleep while each sitemap is generated?

@Jules Is the output just one file? And you are appending the content with each iteration?

@Arvin, good question, I had just planned to output to lots of files. I think the best thing to do is lots of files.
