ereg regular expressions finding urls

[Anon]

Hello All,

I am trying to write a program to find all urls in a webpage.

using a friends regular expression

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

and

ereg(...)

I want to find all urls in a webpage, and insert it into an array. My current program does a greedy search and stops at one url. It sometimes dosent find any urls

Please Help

Bob

preg_match_all("/((http|ftp):\/\/[^ ]*)/i",$text,$array)

and check $array[1]

it supposes the URL should not consist of any space inside it... It's simplest against checking all the allowed chars

Depends on how serious you want to get:

Only identifies http and ftp urls; not telnet, mailto, nntp nor any of
the others out there.

$xalpha='([a-zA-Z\d$@.&+!*"\'(),-]|%[\da-fA-F]{2})';
$ialpha="[a-zA-Z]$xalpha+";
$alphanum2='[a-zA-Z\d.+-]';

$search="$xalpha+(+$xalpha+)";
$path="($xalpha+(/$xalpha+))?"

$hostnumber="\d{1,3}(.\d{1,3}){3}";
$hostname="$ialpha(.$ialpha)*";
$host="($hostname|$hostnumber)";

$hostport="$host(:\d+)?";

$user=$password="$alphanum2+";
$ftptype="([AE][NTC]|I|L\d+)";
$login="($user(:$password)?@)?$hostport";

$ftpaddress="ftp://$login/$path(;$ftptype)?";
$httpaddress="http://$hostport($path)?(\?$search)?";

$url="$httpaddress|$ftpaddress";

regexp = "#$url#";

preg_match_all($regexp,$page,$matches);
