Scanning information from a page?

Give PHP the url, can it do the rest?

[Tokey]

Hello,
I'm looking to write a script that would scan a page at a user-specified url and display all of the links on that page. Sort of like how a search engine spider organizes information out of pages. Is this possible using PHP?
Any suggestions on where to start would be appreciated!

sure two things that come to mind are fsockopen [ca.php.net] and curl [ca.php.net].

Thank you! That is exactly what I was looking for.

blah, now i've hit another wall... I have the contents of a page stored to a variable, but I don't know what functions to use to remove everything but <a> tags and their contents from the variable.

any suggestions?

preg_replace or str_replace - PHP.net is down for me right now, or I would have linked.

$text=preg_replace("/[^\[\]]*\[([^\¦]*)\¦([^\]]*)\][^\[]*/i","$1 $2<br>",preg_replace("/<[^\>]*a[^\>][^\>]*href[^\>]*=\s*([\"']?[^\>]*[\"']?)[^\>]*\>([^\<]*)\<[^\>]*\/a[^\>]*>/i","[$1¦$2]",$text));

(tested - don't forget to turn ¦ into a real pipe)
