• Show parts of the result of an SQL statement using PHP

  - by mouthpiec

  I have an SQL query which returns a set of data (around 40-50 tuples). I would like to display the results 5 at a time on an HTML page using PHP. I already managed to have the right SELECT statement, but i am having problems to display the results 5 by 5 using a "more" button. Can you please help? Note that every time i call the query, the data is being randomized, so it is not possible to set limits and call the query again. I have to find the method to store the results somewhere, and then show them 5 by 5.

• PHP New Line will not work

  - by user364333

  Hi I am trying to create some code that first reads the existing contents of the file in and then adds the new line of code on a new line but the code i am using just adds it on the new text on to the already existing line instead of the new line... Here is the code i am using: <?php $id = $_GET['id']; $userfile = "user1.txt"; $fo = fopen($userfile, 'r') or die("can't open favourites file"); $currentdata = fread($fo, filesize($userfile)); fclose($fo); $fw = fopen($userfile, 'w') or die("can't open favourites file"); $currentprocessed = "$currentdata\n"; fwrite($fw, $currentprocessed); fwrite($fw, $id); fclose($fw); ?> I have tried a whole range of different ideas but nothing has worked, any help would be appreciated.

• mysql PHP query question

  - by camran

  Ok, i have a problem here... I am sending values of drop down lists via ajax to this PHP file. Now I want to search a mysql database using these values, which I have managed to do, BUT, only if I set the values to something... Take a look: $query = "SELECT * FROM cars_db WHERE price BETWEEN '$cars_price_from' AND '$cars_price_to' AND year BETWEEN '$cars_year_from' AND '$cars_year_to' AND mileage BETWEEN '$cars_mileage_from' AND '$cars_mileage_to' AND gearbox = '$cars_gearbox' AND fuel = '$cars_fuel'"; now, what if the user doesnt select any "price_from" or "year_from"... The fields are only optional, so if the user doesnt enter any "price from" or "year from", then the user wants ALL cars to show... Do I have to write a query statement for each case or is there another way?

• [php + mysql] Save IP in database

  - by Knarf

  When a user logs inn I want to save their IP in the database. How would I do that? What type is best to use for the MySQL field? How would the PHP code to get IP look like? I'm thinking of using it as an extra security feature for the login/session stuff. I'm thinking of checking the IP the user logged in with from the DB with the IP the user have now as addition to checking the session. So that it first check the session, and then check if you have a valid IP. Is that an allright extra feature? And what other things can I do to make it more secure?

• Block upload of executable images (PHP)

  - by James Simpson

  It has come to my attention that a user has been trying to create an exploit through avatar image uploads. This was discovered when a user reported to me that they were getting a notice from their Norton Anti-virus saying "HTTP Suspicious Executable Image Download." This warning was referencing the user's avatar image. I don't think they had actually achieved anything in the way of stealing information or anything like that, but I assume it could be possible if the hole is left open long enough. I use PHP to upload the image files, and I check if the file being uploaded is a png, jpg, or gif.

• PHP inheriting/extending a particular instance of an Object

  - by delta9

  Is there any way to force PHP to extend an existing/particular (and for that matter, already instantiated) instance of an object? This imaginary code should explain what I am wondering: class Base { public $var; function __construct($var){ $this->var = $name; } } class Extender extends Base { function __construct($parent) { parent = $parent; } } $base = new Base('yay!'); $extender = new Extender($base); echo 'Extended base var value: '.$extender->var.'<br/>'; Output (would be): Extended base var value: yay! To be clear, I am wanting to instantiate an object that extends a PARTICULAR INSTANCE of another object, one that has already been instantiated. I am aware that I can pass a reference to an object to another object (via it's constructor function) and then add it as a property of the receiving object, I'm wondering if there is a real way to do this?

• Generate a valid array key from an URL string in PHP

  - by John Riche

  I have a PHP array with some predefined values: $aArray = array( 0 => 'value0', 1 => 'value1' ); I need to create a function where the string input will always return the same, valid, array key so that when I call: GiveMeAKey('http://www.google.com'); // May return 0 or 1 I receive always the same key (I don't care which one) from the array. Obvisously I can't store the relationship in a database and the string passed to the GiveMeAKey method can be any URL. I wonder if there is a way of doing that ?

• Anyway to improve my gzip PHP method?

  - by Joe

  I Gzip my pages currently like so: <?php ob_start("ob_gzhandler"); //my page content ob_flush(); ?> However, I read a comment somewhere, earlier on, that this method uses a lot of memory, and I know that my website has been using a lot of memory on my virtual private server, so I thought it would be nice if I knew a way to reduce memory usage. I tested my site with an online gzip tester which says my websites are sending gzipped pages, so my gzip method works, but the main obviously I'm looking for a less memory intensive option, if any. I appreciate all suggestions. :) Oh and merry christmas ;P

• PHP: Iterate through folders and display HTML contends

  - by Mestika

  Hi, I’m currently trying to develop a method to get a overview of all my different web templates I’ve created and (legally) downloaded over the years. I thought about a displaying them like Wordpress is previewing it’s templates view a small preview windows, displaying the concrete file with styles and everything. How to divide them into rows and columns and create AJAX modal window open on preview and pagination and so on I believe I can manage, but it is the concept itself about iterate over several folders then find all index.htm / index.html pages and displaying them. I’ve not worked very much with directories in PHP and the only references and code stumps I’ve found so far is just to list all the files in a certain directory like, what it contains. I would be really grateful if someone knew about a script, a function, snippet or just could get me a nudge in the right direction to create such a (probably simple) preview function.

• PHP callback function not being called

  - by Industrial

  Hi everyone, I've got the following code: function _callback_memcache_failure($host, $port) { print "memcache '$host:$port' failed"; } $this->memcache = new Memcache; $this->memcache->addServer('192.168.1.35', '11211', 0, 50, 10, TRUE, _callback_memcache_failure('192.168.1.35','11211')); The server is online and running (verified!), but the Failure callback function is being called at each connection. Why is that? Reference: PHP documentation: Memcache::addServer - failure_callback Allows the user to specify a callback function to run upon encountering an error. The callback is run before failover is attempted. The function takes two parameters, the hostname and port of the failed server .

• How do I log the raw HTTP headers with a PHP script?

  - by php

  I'm using a cURL script to send POST data through a proxy to a script and I want to see what raw HTTP headers the cURL script is sending. List of things I've tried: echo curl_getinfo($ch, CURLINFO_HEADER_OUT) gives no output. file_get_contents('php://input') gets some HTTP headers but not all. print_r($_SERVER) also gets some HTTP headers but not all (I know this because there should be a X-Forwarded-For header and there isn't) Printing all superglobals ($_POST, $_GET, $_REQUEST, $_FILES etc) still doesn't show the raw HTTP headers. http_get_request_headers(), apache_request_headers(), $http_response_header, $HTTP_RAW_POST_DATA aren't outputting everything. Help?
