PHP To find all url in a given page

[Anon]

Hello,

I need some help with a program to find all urls in a specific page. I've tried all the regular expressions but still not working.
ireg gives me errors.

I'm trying to write a php program to extract all urls from a given webpage.

Please help

Regular expressions are your best bet. Try this little regex:

((http|ftp)://)(([a-z0-9-])+.)(([a-z0-9-])+(.)?)(\/)

It's not complete, but I'm working on the same thing.

Yet another example: get the text, link URLs using this function and show it to user...

function MarkLinks($s)
{
$s=ereg_replace("([hH][tT][tT][pP][sS]{0,1}://[a-zA-Z0-9.=?+%~#:&/-]+)","<A TARGET=blank HREF=\"\1\">\1</A>",$s);
return ereg_replace("([a-zA-Z0-9.-]+@[a-zA-Z0-9.-]+)","<A TARGET=_blank HREF=\"mailto:\1\">\1</A>",$s);

}

Yes,

Im trying that with the ereg(..) but it does not work...?? I gives me a error.

Plus it does a gready find...and return the entire string. I would like to extract all links and put it into an array...I want the array to be an array of all links in a webpage.

$theurl + "http://www.yahoo.com";

if(!($fp = fopen($theurl, "r")))
{
echo "Could not open URL";
exit;
}

$contents = fread($fp, 1000000);
fclose($fp);

$pattern = "((http|ftp)://)(([a-z0-9-])+.)(([a-z0-9-])+(.)?)(\/)";

if (eregi($pattern, $contents, $foundurls))
{
echo "The url found is:";
echo $foundurls[1];
} else
{
echo "Cannot any urls";
}

Please help
