Getting all hrefs and sorting them


tau9

Recommended Posts

Hi,

 

I am trying to write a web crawler that goes to a number of sites and then retrieves data. i.e.

 

If someone entered i.e. Gordon Brown they would get a list of hrefs with titles about the PM and links would be activated.

 

I have some code that I have seen on other posts shown below:

 

<?php

 

 

$code = file_get_contents('http://news.bbc.co.uk/#top');

preg_match_all('#href=[\'"]([^\'"]+)[\'"]#i', $code, $matches);

echo '<pre>'.print_r($matches[1], true);

 

 

?>

 

But not sure how I would sort through to find topics related to the User Input i.e. Gordon Brown.

 

Does anyone have any idea how to do this some suggestions on how?

 

Thanks in advance
