3//HSp33der Web Crawler 5.5
4//<-Harvie 2oo7
5/*
6 * Description:
7 * This script crawls the web and printing found URLs to STDOUT.
8 *
9 * Installation:
10 * - Debian:
11 * # apt-get install php5-cli php5-curl curl
12 * $ chmod +x crawler.php
13 * $ ./crawler.php (or $ php crawler.php)
14 * - Windows:
15 * c:/>path/to/php5/php.exe crawler.php
16 * (you can add php.exe to PATH or associate .php files with it)
17 *
18 * Notes:
19 * - You can use EtherApe (or similar sniffer) to get graphical
20 * illustration of connecions (spider with your machine in center).
21 * - There are few bugs in PHP5,
22 * so this crawler may freeze after few minutes,
23 * but you can use $use_curlbin option (need some extra files).
24 * Check this for more info: http://bugs.php.net/bug.php?id=43098
25 *
26 * Tips & Tricks:
27 * - Make found URLs 100% unique:
28 * cat urls.txt | sort -u > uurls.txt && mv -f uurls.txt urls.txt
29 * - Show filesize and total urls count:
30 * du -h urls.txt && cat urls.txt | wc -l
31 * - Open another output pipe:
32 * tail -f urls.txt
33 * - Use some plugin (filter) to extract emails, etc...
34 * tail -f urls.txt | ./example_mail_extractor.php
35 *
36 * Dedicated to: SooM.cz (This is SooM project)
37 * Special thx2:
38 * - PHP, cURL (technology)
39 * - root.cz & php.net (help)
40 * - Linus Torvalds (because I am crawling from Linux)
