searching a page for links and putting links into array - beginner

Hi all, I'm trying to search a page for links and put the links into an array. Is there a specific function for doing this, or do I have to search for '<a href="' then read the link in.

I'm thinking of something like this:

$file = fopen("links.html","r");
while (!feof($file))
{
// get line from file
// check if it's a link
// put link into array
}
fclose($file);

Code (markup):

Does anyone have any ideas?

 

you can using regex to catch links .
search in google regex or using a thread in this section with regex help .

 

Try something like this:

function grablinks($filename)
{
	// grab the lines in the file
	$lines = file($filename);
	foreach ($lines as $line)
	{
		// in each line find all <a ... href="..." .../> tags and extract the actual link
		$count = preg_match_all("/<a[^>]*href=[\"']([^\"']*)[\"'][^>]*>/", $line, $matches);
		// if there was at least one link found in the current line
		if ($count > 0)
		{
			// do something with all matched links 
			for ($i=0; $i<count($matches[0]); $i++)
				echo $matches[1][$i] . "<br/>";
		}
	}
}
