I'm looking to stop image leeching on my server by using a fancypants URL hiding script.

I have images on a few different image servers and I am looking to hide the URL of them by doing something like the SA's attachment.php image output script where showimage.php outputs the image data and showimage.php checks whether it's pulling the file from one of my scripts, if it's true - it outputs the image data.

[index.php]

<img src="showimage.php?server=2&filename=sweet.jpg">

[/index.php]

Any help or pointer towards this would be appreciated.

How do I get the data of say, http://55.55.55.55/image.jpg or http://myimageserver.com/image.jpg into $imagedata?

php:

<?php
ob_start();
$imagedata = how_do_i_get_data("http://blah.com/image.jpg");
$length = strlen($imagedata);
header('Last-Modified: '.date('r'));
header('Accept-Ranges: bytes');
header('Content-Length: '.$length);
header('Content-Type: image/jpeg');
print($imagedata);
ob_end_flush();

if cURL isn't enabled, use file_get_contents:

<?php
$file = file_get_contents( 'http://path/.jpg' );

Thank you. For my purposes and level of PHP, this works perfect.

I am now streaming images from my site from multiple servers seamlessly, whilst hiding the IP of the servers.

Without setting a cookie, session or global variable, I need to pass a variable from index.php to a PHP script included as an image.
eg

php:

<?
// index.php
global $inIndex = true;

[code]

<img src='showImage.php?param1=yay&param2=wee'>
?>

php:

<?
// showImage.php
global $inIndex;

if ($inIndex == true)
 { //show real image }
else
 { //show fuckoff.jpg }
?>

I was using ip2c (free IP to country database) for a while until it broke. Even the new version keeps breaking, I pasted the errors on pastebin.

Has anybody experienced this too, or any idea why?

The PHP files DO point to the database files correctly, which confused me.

Looks like you are using a relative path (fopen(../ip-to-country.bin)), do you still get the errors when you use an absolute path?

Failing that, maybe try Maxmind's GeoIP database, it's been working great for me.

sample.php, geoip.inc, GeoIP.dat all in the same dir (domain.com/ip2c)
path in sample.php is correct:

$gi = geoip_open("/home/removed/public_html/ip2c/GeoIPCity.dat",GEOIP_STANDARD);

Still not working:

Warning: fopen(/home/removed/public_html/ip2c/GeoIPCity.dat) [function.fopen]: failed to open stream: No such file or directory in /home/removed/public_html/ip2c/geoip.inc on line 314

Line 314 just includes the var $gi

EDIT: Fixed, standard file in the code is GeoIPCity.dat, I just had GeoIP.dat.

The file is uploaded fine and the location of the file is in $file, I then want something like $Col1[0] $Col2[0] and $Col3[0] respectively with the 200 or so rows that are in the file.

Your first question could have been answered by googling "php csv" (fgetcsv is the FIRST RESULT). Now you have copied and pasted the example code from that page and asked another extremely basic question that you should be able to figure out on your own. Either pay somebody to write this script for you or actually take the time to learn how to write it.

I'm learning. So gently caress off jerkbag.

Come on, man. You're not even trying. Your previous post seems to indicate that you know how an array works, so how can you not be able to figure out what you want to do from the example you copied?

Here's a hint: $data is an array of the columns.

Thank you. I'm not sure if this was the easiest way to go about it but it works for me:

php:

<?
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
    $num = count($data);
    
    $row++;
    
    for ($c=0; $c < $num; $c++) {
        
    $entry[$row-1][$c+1] = $data[$c];   //this line
    }
}
?>

So I can call entry[1][2] for row 1, column 2.

I'm creating a little quiz script and I'm looking for ideas on how I can ask the database if the answer they have clicked on is correct without transmitting any visable indication in the source that he should click a certain one.

My database fields (that we'll use in this query) are
q_id (Unique ID of that question)
q_question (The question at hand)
q_correcta (The correct answer)
q_seconda (A wrong answer)
q_thirda (Another wrong answer)
q_fourtha (The last wrong answer)

I could transmit the answer back

php:

<?
<input type="button" value="Answer Here">?>

and compare that field to the correcta on submission, but I'm assuming it will start spitting out "wrong answer" messages when the correct answer is clicked if the answer contains certain characters. At the moment the desisn is using one form, with 4 submit buttons but I feel to pass the necesary information on, I'd need to use 4 forms, 4 buttons.

Would I need to have a variable inside each form with an md5 of the answer like so (x4)

php:

<?
<form method="POST">
    <input type="hidden" name="answer" value="xxxxxMD5HERExxxxx">
    <input type="submit" name="Answer1" value="This Is Answer 1"></p>
</form>?>

Can anybody point me in a direction of a simpler solution or clarify that I am indeed heading in the right direction before I over complicate this even more?

Thanks for the pointers sirs, now I have another annoyance.

The more questions they answer, the more likely it is that a question they've already answered will come up. If I store which q_ids they do in a string inside a cookie or session, is it possible with a simple query to do a

SELECT * FROM questions WHERE q_id != $IN_THIS_ARRAY() ORDER BY rand( ) LIMIT 1

Or something similar?

Crap, how do I avoid the header already sent spaz out that PHP has when I retrieve and edit (remove) a cookie in the middle of my script. Simply moving it to the top of this script isn't possible because it's an include and the main index.php is outputted before this is called.

php:

<?
{lots of code}
    $prevcorrect = $_COOKIE["cookiename"];
    setcookie("cookiename", 0, time()-604800, "/", ".mydomain.co.uk", 0);
{lots of code}
?>

Or would it be a lot more simple to set a session in the other script, then destory the session here; or would I come up with the same problem?

MrEnigma posted:

Sessions would fix this, but they also do not persist for a user when they come back (although you could somehow use a cookie to reactivate a session...or other craziness like that).

A cookie has to be sent in the headers, which means it has to go before any output. This means, you'll either need to figure out a way to get that cookie set at the top of the page (or on a new page), or you need to output buffer the page.

Either way I'll have to recode index.php to and call cookies and/or initiate the session at the top. I'll play around with buffer.

The value is only passed from one page to the other but using session/cookie to avoid any interference with the value. Is there any way I can set the variable in this script, redirect, then request the variable data from the previous page without having to submit a 'form'.

Yeah, really do try to separate your code from your templating as much as possible by getting most of your code out of the way before output happens. I know it's not totally possible short of using something like Smarty because of stuff like database result loops which end up in the middle of the page, but it does make it much easier to manage things that need to be done before the header gets sent out.

I will try that in future, thanks for the advice. Although I am still learning, I'm pretty confident what I am coding now (with assistance from you guys) is going to work pretty well. I appreciate all the pointers you guys have given me so far.

A few days ago I decided to see what type of neat text encryption PHP can do.

I stumbled upon this and within the same execution cycle it works fine:

php:

<?
   //encrypt3.php?key=balls&text=i like to move it move it
    $key_value = $_REQUEST["key"];
    $plain_text = $_REQUEST["text"];
    echo "key = '$key_value' and text = '$plain_text'<br>";
    $encrypted_text = mcrypt_ecb(MCRYPT_DES, $key_value, $plain_text, MCRYPT_ENCRYPT);
    echo "encrypted text = '$encrypted_text'<br>";
    $decrypted_text = mcrypt_ecb(MCRYPT_DES, $key_value, $encrypted_text, MCRYPT_DECRYPT);
    $decrypted_text = trim($decrypted_text);
    echo "decrypted text = '$decrypted_text'";?>

shows the output

code:

key = 'balls' and text = 'i like to move it move it'
encrypted text = '��'}OXh׍��P���:|�V�.���{�'
decrypted text = 'i like to move it move it'

But as soon as I start submitting it with a html form with encrypted text, funny things start happening, here's my form code: http://pastebin.com/m77339235

Comparing the output of my test script with the output from my main form, it's encrypting fine. It just seems the special characters aren't being transmitted to the server correctly when deycrpting. Could anybody please give me pointers why?

Thanks guys. The I am getting is a URL from a XML based web service.

I've been echoing crap out everywhere to see where my data isn't being passed, heres what i've found so far.

some_functions.php
- contains some_function(a,b,c,d);
- some_function(a,b,c,d) contains

php:

<?
<snip>
$request = "http://".$host.$uri."?".$canonicalized_query."&Signature=".$signature;
    
// do request
    $response = file_get_contents($request);
    echo "Debug: <a href='$request'>Query</a> = $request (response = $response)<br>";
<snip>
return $someXML?>

returns XML;

some_include.php
- require_once(some_functions.php), calls some_function();
- echos query = fine, response = fine

index.php
- includes some_include.php
- echos query = fine, response = blank

I'm not exactly sure what you mean but I found the cURL class, but I am not receiving any errors to indicate i'm doing it wrong or any data back

php:

<?
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, '$request');
        $response = curl_exec ($ch);
        curl_close ($ch);
?>

As per above debug echos, query = fine (accessible and viewable by URL, returns XML to browser), response = blank
