Parsing Web Sites

[Colum]

Hi I need to parse particular web sites to extract paritcular information on
a weekly basis. How is this done in PHP and is PHP better at doing this than
JSP?

$remote = file_get_conten ts ('http://www.somesite.co m/');

Now string $remote contains the entire index file for
http://www.somesite.com/. You can parse it, extract anything
you want from it, or do whatever you please with it.

As to the weekly basis, PHP itself has no scheduling tools.
You will have to use OS-level scheduling via cron on Unix
or Scheduler on Windows.

This is a very basic functionality, so it's highly unlikely
one scripting environment will be much better at it than
another...

This is only available on php 4.3+ -- many hosts still only support
4.2.x or less... (like CIHost)

In case of php4.2-, use fsockopen and fgets

If the host in question has the fopen wrappers enabled, you only need to use
file() or fopen() and fread(); socket functions would be an overkill for
that simple task.

Unless you're a search engine, you're not gonna make yourself too
popular by harvesting information from other people's sites.
