PHP - Php Bypass System Host File
HI all, this is a strange request so bear with me. I have setup a server on my local machine, what I want to do is scrape info off the real server out on the internet in some of the pages. I have that working using curl for different domains, but the issue is I have a 127.0.0.1 host entry for the domain in question because the local server name has to match the real server name for the application to run. I can get the real IP using a shell ie: echo exec('nslookup example.com 1.1.1.1'); but I don't know how to get curl to use that IP or force curl to use a different name server, any ideas?
CURL code:
thanks in advance!!
$url = "http://example.com/index.php";
$fields = [
'id' => '1234'
];
$fields_string = http_build_query($fields);
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, true);
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);
curl_setopt($ch,CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
echo $result;

I know this is possible as torrentflux caters for this but unsure of where to start. I dont want to allow file or directory uploads or creation in my /etc/php.ini file (this is turned off). Yet then torrentflux allows me to link a torrent from an external source (using legal downloads of course ) but then it uploads it on my server and creates folders on a per user basis. How is this possible can someone give me some pointers please? I look forward to any replies, Jeremy.

<div class="view-btn2"> when i click on view more its directing to login page.Please help me to resolve this issue. Hello, I'm trying to create a file in my home dir and in my etc folder but I keep getting permission denied.
I am doing this
$myFile = "/home/ng/http/uid.txt"; during lesson time we're developing php systems and our topic is virtual storage like dropbox, google drive etc. My teacher has now set the task to enable the ability to share files within the server but also restrict access within the server folder. I'm being taught MySQL however I've read a lot about PDO being better and decided to use this method to try and get a higher grade for my project although I'm having difficulty understanding how to go about it what i want to achieve is:
creating file sharing capability (i.e. students can share group projects)
restricting users (only those working on a particular document can view it)
don't worry this is not for my own benefit I'm just trying to get a grade here, I mainly just want advice on what I need I've read quite a bit but unfortunately I'm more of a visual learner.
I have been following a tutorial to create my first php application, a file (image) uploading system. I am hoping to add it to my site, http://www.kalam1ty.com/upload.php I have read through the code multiple times and cannot find out what is wrong. I have tried to fix this for about half an hour now and cannot seem to find where the code is wrong. It does not generate any errors and passes all of the checks that I wrote, it just does not upload the image. Nothing in the upload part of the script looks off to me, but I am a PHP newbie, and am not 100% sure. Here is the whole page's code: Code: [Select] <?php if(isset($_FILES['image'])) { $errors = array(); $allowed_ext = array('jpg', 'jpeg', 'png', 'gif'); $file_name = $_FILES['image']['name']; $file_ext = strtolower(end(explode('.', $file_name ))); $file_size = $_FILES['image']['size']; $file_tmp = $_FILES['image']['tmp']; if(in_array($file_ext, $allowed_ext) === false) { $errors[] = 'Extionsion not allowed.'; } if($file_size > 10485760) { $errors[] = 'File too large. Must be under 10MB.'; } if(empty($errors)) { //upload file if (move_uploaded_file($file_tmp, 'uploads/images'.$file_name)) { echo 'File uploaded to kalam1ty.com/uploads/images/'; } } else { foreach ($errors as $error) { echo $error, '<br>'; } } } ?> <html> <head> <title> Kalam1ty - Home </title> <link rel="stylesheet" type="text/css" href="style.css" /> <link href='http://fonts.googleapis.com/css?family=Anonymous+Pro' rel='stylesheet' type='text/css'> <link rel="shortcut icon" href="/home/corona/Development/Web/favicon.ico" type="image/x-icon" /> <meta name="google" value="notranslate"> </head> <body> <div id="EncBG"> <div id="Navbar"> <a href="index.php">Home</a> <a href="downloads.php">Downloads</a> <a href="upload.php">Upload</a> <a href="contact.php">Contact</a> </div> <div id="Enc1"> <div id="Content"> <h2>Upload Files</h2> <form action='' method='POST' enctype='multipart/form-data'> <p> <input type='file' name='image'> <input type='submit' value='Upload'> </p> </form> </div> </div> <div id="Footer" class="whitetext" align="center"> <b><i> <a href="index.html">HOME</a> // <a href="downloads.html">DOWNLOADS</a> // <a href="#">OTHER</a> </b></i><br> <img src="smlogo.png" alt="Kalam1ty"/> </div> </div> </body> </html> Thank you guys very much if you can help me! Hi Everyone, this is a very old code. I know I have to change the 'addslashes' method in this code. I also just changed the code using 'mysqli'. There are two files to upload the images to a gallery, preexport.php and export.php. The upload works up to five images. if I choose 6 or more and press add images, the browser refreshes itself and the upload won't happen. All the fields on the form clears itself and no errors shows up...can you please take a look and help me correct this problem? Here are the two files...

In order to learn as much as i can bout PHP i want to do some tests and write some scripts. Well the WAMP is allready up and running. Now i try to give the writing access to the folder mkdir /srv/www/ where the php-scripts should go in... i want to give write permission to all to all files in /srv/www As root I generally: mkdir /srv/www/ chown <webmaster usrername> /srv/www/ /srv/www/ should be readable and traversable by all, but only writeable by it's owner (the user designated as the webmaster.) can i do this like mentioned above,... Love to hear from you greetings db1 I am creating a news updates thing for my website and i have managed to get it working on my home PC (im using XAMPP) but when i upload to my webhost it doesnt appear to work. I am wondering if it is just my host or whether i have done something wrong and by chance it works on my home PC. Here is my code: <?php include("includes.php"); doConnect(); $get_news = "SELECT title, text, DATE_FORMAT(datetime, '%e %b %Y at %T') AS datetime FROM newsfeed ORDER BY datetime DESC"; $result= mysqli_query($mysqli, $get_news) or die(mysqli_error($mysqli)); while ($row = mysqli_fetch_array($result)) { echo '<strong>'. $row['title'] .' </strong><br>'. $row['text'] .'<br>'. $row['datetime'] .'<br><br>';} ?> My includes file is: <?php function doConnect() { global $mysqli; //connect to server and select database $mysqli = mysqli_connect("localhost", "user", "password", "dbname"); //if connection fails, stop script execution if (mysqli_connect_errno()) { printf("Connection failed: %s\n", mysqli_connect_error()); exit(); } } ?> I think im right in saying it connects properly because i do not see an error. what i get is: Code: [Select] '. $row['title'] .' '. $row['text'] .' '. $row['datetime'] .' ';} ?> Im new to PHP (incase you hadnt guessed!) so not really sure whats happening. On my home PC i have PHP Version 5.3.1 and on my webhost its 5.2.14. Home PC mySQL version 5.1.41 and on webhost its 5.0.91-community. Could this be the reason? Thanks I currently have a list of host addresses. I need to get the mx records for them. I was looking at the documentation, and found the getmxrr(). Would that send back the mx record, or just true if it has one? Hi, I just realised that date() function depends on where ever your hosting company is from. Is there any way to change this manually as I am from UK and the day changes early compared to where my hosting company is (USA). The reason I want to know this because I have some functions where the user should only be allowed to choose the current date which I want to be according to GMT time. Any help is much appreciated thanks in advance! Hi all, I have a small script I found somewhere but after I changed hosting, it just stop to work. I just want to record the user IP and Referrer etc. in a .txt file using fopen. It helps to see what users searched for in search engine etc. The headers are there but no data... Please help?? session_start(); if($session["logged"] != "yes") { $agent = $_SERVER['HTTP_USER_AGENT']; $uri = $_SERVER['REUEST_URI']; $ip = $_SERVER['REMOTE_ADDR']; $ref = $_SERVER['HTTP_REFERER']; $visitTime = date("r"); $logLine = "$visitTime - IP: $ip || User Agent: $agent || Page: $uri || Refererrer: $ref\n\n"; $fp = fopen("indexLog.txt", "a"); fputs($fp, $logLine); fclose($fp); $_SESSION["logged"] = "yes"; } ?> Thanx in advance Jaco HI, My host support pop protocol. I want my host to receive emails and do some process on it with php coding and then store then.But I don't know how to receive emails using my host and how can I have access to them to do some process on it. How can I do that? Thanks Hi, i have this code Code: [Select] print get_domain("http://www.somedomain.com"); function get_domain($url) { $pieces = parse_url($url); $domain = isset($pieces['host']) ? $pieces['host'] : ''; if (preg_match('/(?P<domain>[a-z0-9][a-z0-9\-]{1,63}\.[a-z\.]{2,6})$/i', $domain, $regs)) { return $regs['domain']; } return false; } mysql_query("INSERT INTO table VALUES('', '$domain')"); And i want to check that the www.somedomain.com is not an ipaddress or localhost (i.e. localhost, 127.*.*.*, - Local 192.168.*.* -LAN or *.*.*.* (as an ip) - Actual IP Any help would be much appreciated thanks, jack I changed web hosting companies and now a php form that was working is no longer working. I haven't been able to figure out what the problem is. The form is a simple text input form that adds the text to a database. Every time the user inserts text with a comma, an error occurs. Below is the code for the form. Any help is much appreciated. Hey.. hoping someone can help me on a this issue I have been having for 4 days now. My host has tried to figure out what is causing it and has told me they are finding it very strange, everytime my website is up on their server it will take 600%-800% CPU so they must take it down for fair usage on other customers of course. They said they can easily track and trace websites that are overloading the resources but mine seems too complicated to understand as it is having legitmate traffic (on average 30 users online and 300 visits daily) which would never be the cause of CPU spikes to 600%-800%. They either believe it is a "clever attack" or some PHP script perhaps looping like mad. Anyone help me and my host figure out the problem as we obviously both don't like the website to continue to be offline. The website has very standard content CMS running and clean database it makes no sense to the both of us. Like to mention the last activity I had done on the website was when I tried to insert into database:- Code: [Select] Query failed: errorno=126 error=Incorrect key file for table './teamxcom_webspell/ws_bi2_cup_matches.MYI'; try to repair it query=DELETE FROM ws_bi2_cup_matches WHERE matchno='5' && type='gs' && ladID='0' && 1on1='1' Then after I tried to perform query from database: Code: [Select] Error SQL query: SELECT * FROM `ws_bi2_cup_matches` ORDER BY `ws_bi2_cup_matches`.`matchID` DESC LIMIT 0 , 30 MySQL said: #1030 - Got error 134 from storage engine Then found out the table on phpmyadmin had wrong page numbers in sequence:- 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 379, 746, 1113, --, --, --7349 After I contacted web host they mentioned it is causinga massive problem and took it down after that. Anyone can shed some light on this please? Sorry if it is posted in wrong section! Thanks very much My web host wont turn on Curl.dll is there any other way to do this with out using Curl #---------------------------------------------------------------------------- # Curl code to store XML data from PWA in a variable #---------------------------------------------------------------------------- $ch = curl_init(); $timeout = 0; // set to zero for no timeout curl_setopt($ch, CURLOPT_URL, $file); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout); curl_setopt($ch, CURLOPT_HTTPHEADER, array( 'Authorization: AuthSub token="' . $GDATA_TOKEN .

Currently, to view my test website you go to... http://www.doubledee.byethost2.com/ I suppose that could be "BASE_URL", but for where things are physically stored so I can redefine "WEB_ROOT" I have no clue... Help! Thanks, Debbie |
