  • Does HTML5 make Javascript gaming safer (more secure)?

    - by Sean Madigan
    I know that Javascript is an incredibly unsecure way of programming a persistent game, where for instance you are doing battle calculations in an RPG and then award XP through linking to a PHP page when they win that adds XP to a database (since the player could make their own javascript to always win or just look at the PHP page that you get sent to when you win and just go there anyway). So with that said, I'm wondering if HTML5 makes multiplayer/persistent games any safer in this regard, since I know it still uses Javascript. Or am I still doomed to rely entirely on server-side scripting for doing any calculations that award the player?

  • Which is more efficient/faster when calling a cached image?

    - by andufo
    Hi, i made an image resizer in php. When an image is resized, it caches a new jpg file with the new dimensions. Next time you call the exact img.php?file=hello.jpg&size=400 it checks if the new jpg has already been created. If it has NOT been created yet, it creates the file and then prints the output (cool). If it ALREADY exists, no new file needs to be generated and instead, it just calls the already cached file. My question is regarding the second scenario. Which of these is faster? redirecting: header('Location: cache/hello_400.jpg');die(); grabbing data and printing the cached file: $data = file_get_contents('cache/hello_400.jpg'); header('Content-type: '.$mime); header('Content-Length: '.strlen($data)); echo $data; Any other ways to improve this?

  • holding session state with zend framework in iframe?

    - by princyp
    I have a php site optimized for iphone, its currently running inside of an iframe in a uiwebview objective c wrapper. Everything currently works except for the sessions inside of the iframe, Im assuming this is due to the cross domain issue with iframes and sessions? my solution is to save the sessions to the db. Is this the best solution? Will this even solve my problem? should I use memcache instead? are there any good tutorials for doing this? I havent been able to find an easy to implement solution for saving the session data, im a bit confused by the bootstrap.php and I keep getting this error when I try to add session saving: 'no adapter found for Zend_Session_SaveHandler_DbTable' any help would be greatly appreciated, thank you

  • Lazy loading? Better avoiding it?

    - by Charlie Pigarelli
    I just read about this design pattern: Lazy Load. And, since in the application i'm working on i have all the classes in one folder, i was wondering if this pattern could just make me avoiding the include() function for every class. I mean: It's nice to know that if i forgot to include a class, PHP, before falling into an error, trough an __autoload() function try to get it. But is it fine enough to just don't care about including classes and let PHP do it by your own every time? Or we should write __autoload() just in case it is needed?

  • Doctrine SQL Server uniqueidentifier isn't cast as char or nvarchar when retrieved from the database

    - by Tres
    When I retrieve a record from the database which has a column of type "uniqueidentifier", Doctrine fills it with "null" rather than the unique id from the database. Some research and testing has brought this down to a PDO/dblib driver issue. When directly querying via PDO, null is returned in place of the unique id. For reference, http://trac.doctrine-project.org/ticket/1096, has a bit on this, however, it was updated 11 months ago with no comment for resolution. A way around this, as mentioned at http://bugs.php.net/bug.php?id=24752&edit=1, is to cast the column as a char. However, it doesn't seem Doctrine exposes the native field type outside of generating models which makes it a bit hard to detect uniqueidentifier types and cast them internally when building the sql query. Has anyone found a workaround for this?

  • Why are cookies only sent to http://www.example.com and NOT http://example.com?

    - by Axel
    I have a PHP login which sets 2 cookies once someone login. The problem is that if you login from http://www.example.com and you go to http://example.com, you will find yourself not logged in. I think that is because the browser only send the cookies to the first syntax. It is only one domain, the difference is the www. before the domain name, so how to set cookies to the whole domain whatever there is www. or not? <?php setcookie('username',$username,time()+3600); ?>

  • phpunit - generate tests for all the classes from a directory

    - by joe
    Hi! I have a directoy structure, and all the classes of the business logic are placed in the app_dir/lib/ directory. I would like to generate unit tests for all the classes from this lib/ folder. The problem is, that I haven't found any option to specify the source directory, only the source file: from app_dir: phpunit --skeleton-class lib/ Error: "lib/.php" could not be opened. Is it the only solution to write my own php script, which iterates through the /lib folder and calls the skeleton generator for every file found? And how can I specify the output folder, where all the generated test files are placed? Thanx, Joe

  • Open zip file without temporary files

    - by Javis Perez
    i've seem this post about extracting a zip without a temporary file via stream and pipes: Open a file from archive without temporary extraction The problem is that i'm using php and have no idea if that is possible. I've search a lot with no luck. My idea is to preview zip files from the dropbox using its API but i dont want to save the files to a local drive, just preview the content. Any idea if that's possible with php? Almost everything i found is about creating the file, not reading it... :-\ I was thinking that i might try with nodejs, but i know mostly nothing about nodejs, do you think it would support it? Any other idea please? thank you.

  • Client / Server security from mobile to website

    - by Amir Latif
    Hey. Am new to the world of web programming and learning a bunch of fairly simple new pieces of tech, trying to piece them all together. So, we have a simple client (currently iPhone, to move to J2ME soon) that's pulling down lists of data via PHP, which is talking to a MySQL db. I have a rudimentary user/login system so that data is only served to someone who matches a known user etc, either on the website or on the client. All the php scripts on the website that query the DB check to make sure an active session is in place, otherwise dumping the user back to the login screen. I've read a little about SSL and want to know if that is sufficient to protect the website AND the data passing between the server and the client?

  • Call to a member function query() on a non-object

    - by Randy Gonzalez
    Ok, this is so weird!!! I am running PHP Version 5.1.6 when I try and run the code below it gives a fatal error of an object that has not been instantiated. As soon as I un-comment this line of code //$cb_db = new cb_db(USER, PASSWORD, NAME, HOST); everything works. Even though I have declared the $cb_db object as global within in the method. Any help would be greatly appreciated. require_once ( ROOT_CB_CLASSES . 'db.php'); $cb_db = new cb_db(USER, PASSWORD, NAME, HOST); class cb_user { protected function find_by_sql( $sql ) { global $cb_db; //$cb_db = new cb_db(USER, PASSWORD, NAME, HOST); $result_set = $cb_db->query( $sql ); $object_array = array(); while( $row = $cb_db->fetch_array( $result_set ) ) { $object_array[] = self::instantiate( $row ); } return $object_array; } }

    Hi, I'm writing some functions in php using exec() to interrogate a svn. The commands exec("svn list ".$myurl) works. Now, I try to get a path on a svn repository with the checkout command.

But when I do this from a php script using exec(), like this : exec("svn checkout ".$myurl, $dir) it doesn't work. Have you an idea ??

  • Can I get a "base URL" in Wordpress within a template file?

    - by alex
    Usually in my PHP apps I have a base URL setup so I can do things like this <a href="<?php echo BASE_URL; ?>tom/jones">Tom</a> Then I can move my site from development to production and swap it easily and have the change go site wide (and it seems more reliable than <base href="" />. I'm doing up a Wordpress theme, and I am wondering, does WordPress have anything like this built in, or do I need to redefine my own? I can see ABSPATH, but that is the absolute file path in the file system, not something from the document root.

  • MySQL Locks: order of unblocked threads

    - by teehoo
    I have a MySQL ISAM table being accessed my multiple php instances. Right now I'm using a WRITE lock to serialize access to this table. My question is how do I ensure that the PHP instances get served on a First-Come-First-Serve basis? Or is this the default behaviour? The official MySQL documentation doesn't mention anything about the blocked thread order for threads of the same lock type (ie multiple threads attempting a WRITE LOCK). It only mentions that a WRITER will jump to the front of the waiting queue if READERS are waiting.

  • Google Maps API - Marker not showing

    - by popnbrown
    I'm trying to add markers for every single row from a table, that sits on the page. The page is http://www.sravanks.com/first/2013ftcmap.php This is the JS code that's loading the markers: $(document).ready(function() { var mapOptions = { center: new google.maps.LatLng(39.740, -89.503), zoom: 7 }; var map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions); var infowindow = new google.maps.InfoWindow(); /* City Markers */ var cityCircle = new Array(); var i = 0; $.each($('.events tr'), function(index, value) { var name = $(this).find('td:first()').html(); var address = $(this).find('.address').html(); var linkUrl = "http://www.sravanks.com/first/geocode.php?address=" + address; $.ajax({ url: linkUrl }).done(function(data){ var json = $.parseJSON(data.substring(0, data.length-1)); lat = json.results[0].geometry.location.lat; lng = json.results[0].geometry.location.lng; var latlng = new google.maps.LatLng(lat, lng); var marker = new google.maps.Marker({ position: latlng, map: map, icon: 'map-pointer-medium.gif' }); google.maps.event.addListener(marker, 'click', function() { infowindow.setContent(name); infowindow.open(map, marker); cityCircle[i] = new google.maps.Circle({strokeColor: '#00FF00', strokeOpacity: 0.8, strokeWeight: 2, fillColor: '#00FF00', fillOpacity: 0.35, map: map, center: latlng, radius: 144841}); i++; }); }); }); /*Team Markers*/ var markers = {}; var teamName, teamNumber, lat, lng, content; $.each($('.list tr'), function(index, value) { teamName = $(this).find('td.name').html(); teamNumber = $(this).find('td.number').html(); markers[teamNumber] = {}; lat = parseFloat($(this).find('td.lat').html()); lng = parseFloat($(this).find('td.lng').html()); content = "Name: " + teamName + "<br />Number: " + teamNumber; markers[teamNumber]['latlng'] = new google.maps.LatLng(lat, lng); markers[teamNumber]['marker'] = new google.maps.Marker({ position: markers[teamNumber]['latlng'], map: map }); google.maps.event.addListener(markers[teamNumber]['marker'], 'click', function() { infowindow.setContent(content); infowindow.open(map, markers[teamNumber]['marker']); }); }); google.maps.event.addListener(infowindow, 'closeclick', function() { for(var i=0;i<cityCircle.length;i++){ cityCircle[i].setMap(null); } }); }); I've got no errors, but the Team Markers do not show up. The strange thing is that the City Markers do show up. Some more info, the City Markers ajax call is just to a proxy that calls the google geocoding api. Again the link's at http://www.sravanks.com/first/2013ftcmap.php

  • library interposition with dlsym

    - by ZeeGeek
    I'm writing an interposition library to track the usage of some library functions in libc, such as open(), close(), connect(), etc. It works generally well on most of the applications. However, when I try it with PHP, using PHP's MySQL module in particular, none of the function calls to libc inside this module is been tracked (so no connect(), no socket(), etc.). 'strace' told me that the system calls socket(), connect(), etc., took place. Running 'file' on the module and libmysqlclient.so.16.0.0 said that they are all dynamically linked. So it shouldn't be a problem caused by static linkage. What might be the problem? I'm using Fedora 11 64-bit version. Thank you.

  • Symfony sfPHPExcelPlugin in Linux

    - by Tere
    Hi! I'm using the PHPExcel plugin for Symfony 1.4 (sfPHPExcelPlugin) on Ubuntu (using PHP 5.10), with this code for saving the file that I am writing: // Save Excel 2007 file echo date('H:i:s') . " Write to Excel2007 format\n"; $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007'); $objWriter->save(str_replace('.php', '.xlsx', __FILE__)); // Echo done echo date('H:i:s') . " Done writing file.\r\n"; I am sure that the execution is reaching this part of the code, because the echo messages are shown but I am not downloading the Excel file! Could it be because I am trying it in Linux, not in Windows? Thank you!

  • Is it possible to disable the iPhone's automatic hyperlinks?

    - by mririgo
    We send out a notification email whenever we have "phishing" emails reported to us. In these emails, we include a copy-paste of the text inside the original phishing email as a sample of what is reported to us. Our code strips all hyperlinks out of the email via PHP, but still includes (in plain text) the link. When users receive this email in their client (Thunderbird, Outlook, Horde/IMP, etc), the hyperlink is removed. However, the iPhone likes to take web addresses in plain text and automatically turn them into hyperlinks. Is there any possible way to stop this action from happening via a HTML tag or by using PHP to replace certain parts of the hyperlink?
