Html page as input to php procedure

[damezumari]

Is there a way to let the html content of an external url be input to
a php procedure?

Example: I want to show the content of http://server.com/test.html,
but with every occurrence of the word 'chess' replaced by 'go'.

Kind regards,

Jan Nordgreen

Hi,

Yes, it is very easy too.

eg with:
http://nl3.php.net/manual/en/functio...t-contents.php

You just suply an url instead of a file.

Replacing the chess with go can be done with str_replace:

however on many servers you wont be able to access files from other
urls, because this could be abused for a DoS attack

function doSomething ($url)
{
if ($handle = fopen ($url, 'r'))
{
// Do something with the page
fclose ($handle);
return ('Page accessed');
}
}

Or even :

function getPage ($url)
{
return (file_get_contents ($url))
}

Do bear in mind reading web pages over the internet can be a lot
slower than reading from the filesystem. If a server takes longer than
30 seconds to respond when you try to access it then your script will
time out (assuming the default timeout value is still configured,
which it usually is).

In which case, using fsockopen
(<URL:http://php.net/manual/en/function.fsockopen.php>) will be fine.

fopen wrappers won't make DoS attacks more or less likely, they can be
easily initiated from various types of requests. For the most part, it
depends on how many machines are making requests.

Of course, but I heard of some hosters having problems with DoS
attacks started from their servers with fopen. And with an
internetserver and its bandwith one first part of an DoS attack is a
lot easier than with your home internet connection, but of course
you're right, one server is not enough for such an attack
