get links (like a webcrawler would)

scraff

Hi, i need some code to get links from a webpage or string. It needs to get all the links (<a href = "page1.php">click</a>) and store them $link[1] = page1.php kindof thing.

Regular expressions could do that.

preg_match_all('/<a href="([^"]*)"/', $html, $matches);
print_r($matches);

OK, thanks. But this seams to mess up a bit. it prints:

Array(    [0] => Array        (            [0] => <a href=Array ( [0] => /select.php?sel=I2 [1] => humor/index.php [2] => /ringslogos/index.php?id=hedcase [3] => phpchat/phpMyChat.php3 ) ) ">

which makes everyting after it a link to "phpchat/phpMyChat.php3"

Can this be fix?
Please could you explain the code you game me?

Also the $html needs to be from a webpage...so:

$html = get"http://www.site.com/index.html";
preg_match_all('/<a href="([^"]*)"/', $html, $matches); 
print_r($matches);

something like thsi?

Thanks!

[man]print_r[/man] just prints human readable info about a variable. It's an array. With regards to getting the contents of a site, it can be done easily but I would stress the fact that fleecing info. from sites is ethically wrong and in many cases, actually illegal so get the permission of the site owner first.
Then look at [man]fopen[/man] & [man]fread[/man] or [man]file[/man] or [man]curl[/man].
