Here's a quick function I wrote to generate IP address ranges using recursion.
function iprange($oct, $prefix=""){
for($i=1;$i<256;$i++){
if($oct == 1) print("$prefix.$i\\n");
else iprange($oct - 1, "$prefix.$i");
}
}
Just call it with the number of octets you want to generate and the beginning of the IP range.
Example:
iprange(2, "127.0");
Output:
127.0.1.1
127.0.1.2
127.0.1.3
127.0.1.4
127.0.1.5
…
127.0.255.254
127.0.255.255

Google CodeSearch is an awesome tool that has the ability to explain how functions work, how other programmers handled difficult problems.. Or just provide you material to laugh at. Codeulate has a great list of comment swearing. I gotta say, I'm guilty of this too, but at least my anger isn't usually revealed to the world!
A while back when I was first learning AJAX, I decided I wanted to write an interactive PHP/JavaScript shell for executing commands, etc. All the other ones I found either didn't handle directories well, were way too bulky or were backdoored. So, I now present to you JAXED Shell. I haven't extensively tested it, but it should work in the majority of situations.
Enjoy
Commands:
home - return to shell's home directory
clear - clear history box
up/down arrow - go through previous commands
right arrow - file name completion
Wrote this for one of my projects - hopefully it helps you out a little bit. POST data needs to be formatted variable1=value&variable2=value2 and urlencoded.
function CURL($url, $postdat=""){
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)");
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
if($postdat){
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postdat);
}
while(!$dat) $dat = curl_exec($ch);
curl_close($ch);
return $dat;
}
Examples:
$dat = CURL("http://google.com");
$dat = CURL("http://site.com/post.php", "search=bunnies");
