PHP - Fix Up Library Dependency On Shared Host
I am on a shared hosting server running CentOS. I have copied a PHP extension (imagick.so) that was built on similar server to my shared hosting server. I have resolved most of the dependencies by placing the missing files in ~/lib but I have one that I can't figure out how to cope with. I am getting the following error:
Similar TutorialsHi all i was wondering if someone knows a way to make sure an image which is uploaded isn't infected by a virus. I have read about avclam, but if your on a shared host your mostly not allowed to add own software. Isn't there maybe a php trick to resize the image which would magically remove a virus? If anyone knows a nice way or tricks to limit the virus breating space to a certain folder please let me know. I'm trying to use dependency injection to pass a database connection to an object but I'm not sure why it's not working. I have my "dbClass" below that connects to a MySQL database. Code: [Select] class dbClass { public $db; function __construct() { $this->db = mysql_connect("localhost","username","password") or die ('Could not connect: ' . mysql_error()); return $this->db; } } Then I have my "baseClass". This is the class that I want to feed to connection too. Code: [Select] class baseClass { public $mysql_conn; function __construct($db) { $this->mysql_conn = $db; $rs = mysql_select_db("webdev_db", $this->mysql_conn) or die ('Could not connect: ' . mysql_error()); } } And this is my index.php file. The error I'm getting is "supplied argument is not a valid MySQL-Link resource". However I tripled checked and my db connection details are definately correct. Code: [Select] $db = new dbClass(); $baseclass = new baseClass($db); Thanks for any help. I need to create an entity which models the connection between a PHP server and another device so that a web app can change the entity's properties which in turn will update the server DB as well as the other device. A little background information for context is as follows: When a socket clients connects to the PHP server, it will register by providing its GUID, and in turn the server will query its DB to identify the specific client. The client has various other properties associated with the socket connection such as reconnect_timeout, response_timeout, etc, and the associated values will also be stored in the server's DB. While all socket clients use the same approach to communicate to the PHP server, several "flavors" of socket clients exists which use a specific protocol (Modbus/RTU, Modbus/IP, ControlNet, BACnet/IP, BACnet/MSTP, KNX, DALI) to communicate to downstream devices. Based on the used protocol, there will be different properties as well as different methods (i.e. some protocols allow one to query the device to retrieve a list of available data). To create the entity using inheritance, I would likely do so whe class ModbusRtuSocketClient extends ModbusSocketClient (which extends SocketClient) class ModbusIpSocketClient extends ModbusSocketClient (which extends SocketClient) class ControlNetSocketClient extends SocketClient etc.. But instead of doing so by using inheritance, I am thinking that I should do so through injection. For instance, I create an object called SocketClient which just deals with that scope of work and is protocol agnostic. I also create a second object which deals with a given protocol such as ModbusRtuProtocol extends ModbusProtocol extends Protocol. I then do one of the following: $entity = new SocketClient(new ModbusRtuProtocol()); //or $entity = new ModbusRtuProtocol(new SocketClient()); //and do $entity->setSomeSocketClientProperty(123); $entity->getProperty()->setSomeSpecificProtocolProperty(321); $entity->updateEndDevice(); $entityManager->persist($entity); $entityManager->flush(); //or do $values=$entity->queryDevice();
PS. If you think I shouldn't be doing so through injection but through inheritance, please advise.
Could use some help with dependency injection, as I can't seem to find the answer anywhere. Ok, take a quick PHP class:
<?php
namespace myapp;
use myapp\template;
use myapp\order;
class user {
private $template;
public function __construct(template $template) {
$this->template = $template;
}
public function add_order(order $order) {
// do something with $order here
}
}
I'm using the php-di package from http://php-di.org/ right now, but open to changing. My question is, how do I call that "add_order()" method, and have $order injected into it? Constructor injection is easy, and just use:
$container = new Di\Container(); $container->make(myapp\user);
How do I do that, but calling the add_order() method instead? I want something like:
$container = new Di\Container(); $container->make(myapp\user::add_order);
Any help?
Thanks, Matt
I just updated a site as follows: cd /var/www/concrete5 composer update Among other changes, the following were made (more on this later): - Updating concrete5/core (8.5.2 => 8.5.4): Downloading (100%) - Updating doctrine/collections (1.6.4 => 1.6.5): Downloading (100%) - Updating doctrine/lexer (1.2.0 => 1.2.1): Downloading (100%) - Updating doctrine/inflector (1.3.1 => 1.4.3): Downloading (100%) - Updating doctrine/cache (1.10.0 => 1.10.1): Downloading (100%) - Updating doctrine/annotations (1.10.2 => 1.10.3): Downloading (100%) - Updating doctrine/common (2.12.0 => 2.13.3): Downloading (100%) - Updating doctrine/instantiator (1.3.0 => 1.3.1): Downloading (100%) - Updating doctrine/orm (v2.7.2 => v2.7.3): Downloading (100%)
errno: 150 "Foreign key constraint is incorrectly formed I expected I should have first used concrete5's update script, but too late for that. So, then I changed composer.json require concrete5/core from ^8.5 to 8.5.2 hoping to return to the previous state. Concreete5 was downgraded as desired, but now I get the following error: Class 'Doctrine\Common\Persistence\Mapping\Driver\MappingDriverChain' not found On another concrete5 site which still works, I have the following two files, however, on the broken one I only have the second: vendor/doctrine/persistence/lib/Doctrine/Common/Persistence/Mapping/Driver/MappingDriverChain.php:13: class MappingDriverChain extends \Doctrine\Persistence\Mapping\Driver\MappingDriverChain vendor/doctrine/persistence/lib/Doctrine/Persistence/Mapping/Driver/MappingDriverChain.php:17:class MappingDriverChain implements MappingDriverSo, now I will attempt to downgrade doctrine from 2.7.3 to 2.7.2. The base composer.json file has no reference to Doctrine, but there are two other related composer files: vendor/concrete5/doctrine-xml/composer.json

Neither seem to be applicable, but the doctrine version has to be specified somewhere. How does composer determine which version and how can I downgrade the dependency package? Thanks
PS. As a hack solution, I replaced the entire vendor/doctrine directory from one from another site, and have things working. Still, want to know how to do this right. Edited June 12, 2020 by NotionCommotionI'm looking for some clarification here from different viewpoints to understand real world applications. In a previous thread, I suggested to someone that they read up on singleton methods to restrict class duplication (oops!), I was quickly (and rightfully) shot down. I did this after having read through blog posts that also suggested singleton design to stop multiple MySQL connections. At the time I didn't consider that could be useful to some people.. fair enough. Thankfully I don't use singleton methods within my own code, but I do use static methods for most things. Reading through numerous blog posts, tutorials, etc.., it seems like static methods can also be considered anti-design and is something to avoid. So now it seems I'm at a point where I need to rewrite my existing framework & CMS, probably using dependency injection within my classes. I understand how this works, and why it makes sense. What I'm struggling with is understanding how to use dependency injection within a (personal) CMS application. For example - I have a config.ini file I have a class that reads the .ini file, stores the variables, and provides me methods to access them I have a content class that selects the relevant page/component from the DB (db & config dependency), then displays it via my template engine. Within the included view files I call component classes (articles, contact, etc..), each of these require a connection to the DB, which has a config dependency. Here's some code to explain it better - index.php <?php $settings = '/config/config.ini'; $config = new Config($settings); $db = new Database($config); $content = new Content( $db ); // Config may also be passed for content config - keeping it simple for example print $content->loadPage($_GET['page']); // This would now include the code below ?>Let's say that this then loads the article index (through $content->loadPage()). The view would look something like this - article_index.php <?php // Duplicated code $settings = '/config/config.ini'; $config = new Config($settings); $db = new Database($config); // Article code $articles = new Articles_Model($db); return $articles->getArticles(0,15); ?>Now my problem is that I'm duplicating the config and db class calls for no reason. Is the sollution to store these within a registry class? But then I'm creating globals, which again seems anti-design. Or is the problem how I load the active page? Any insights would be much appreciated. This topic has been moved to Application Design. http://www.phpfreaks.com/forums/index.php?topic=346818.0 Was just wondering why some people choose NOT to make use of static functions when initializing objects via Factory Classes/Containers. What are the benefits of initializing the Factory class when for all intensive purposes, it's only used to initialize new classes, etc? Does this have any impact on Dependency Injection? I'm assuming that it doesn't since that would defeat the purpose. --------- Also, I've noticed that there seems to be an intense stigma within the development community in regard to singletons. Are singletons necessarily a bad thing? What about database objects? One argument I've heard is that this can often impact the flexibility of your application in the event that a new instance of said class needs to be initialized(a second completely separate connection). However, I was thinking that you could simply store these objects within a static member variable in the factory class; leaving the Database Class' __construct public in the event that you need to create that second/third/fourth connection. Wouldn't this resolve the issue?
Not experienced coding PHP and need help doing something which is probably very easy but looks like Mt Everest to me. FOO = 123456 BAR = abc Then, write URLs with those variables and have them work the same in a browser:
http://webpage1.com/?var1=FOO&var2=BAR
http://webpage2.com/?var1=FOO&var2=BAR
http://webpage3.com/?var1=FOO&var2=BAR If I update the fields in my local webpage and refresh browser, would like the new value(s) to be used instead. Any help with this greatly appreciated. If someone will put a file together think that I can edit and modify from there for my specific application. Thank you. Edited December 1, 2020 by XcloneHello - I have usually run my own servers, and always drop my .php files with MYSQL connection strings in a directory like /var, with webroot being /var/www/mysite. I now find myself in a shared hosting environment for a client and wondering the safety of my connection string .php files. Unfortunately they are sitting in a folder in the root of my hosting directory right now, and they feel vulnerable. It seems the only thing I could do would be to put the root of my hosting into a subdirectory, point the site there, and then put my connection strings on directory back. But seems the problem is they are still in my shared hosting. What's the best way to secure this type of sensitive info in a shared environment? I'm also getting ready to explore credit card processing via an API, and wondering if shared hosting is even worth it. Thanks!! Ok here it is, seems like it is an easy problem but my developers are having some issue with this, I hope you guys can help. Basic question and answer problem, where I am developing a website that uses Items and questions like " How many of this Item do you need?" the answer seems to simple. Lets say the answer Is "1". The display is given to the Item list and we move on. Here is the Problem: When selecting Muiltiple Items in the List and they all have the same question associated to each Item: "How Many Items do you need?" the the answer is shared between the Items, Again, sounds simple so far, However, when the USER selects Multiple Items on a list say 30 Items then the Question should only be dispalyed one time, not 30 times, then the answer is shared 30 times. Thats what I have now being displayed on my website, 30 of the same questions over and over again. The USER will get frustrated and leave the site never to return. Question: How can I get the Question to be displayed only once, but shared between several items on a list? This is a very serious problem fo my website because I will have not have just one Item on a list but 300 to 400 items, and if I get the answer to the problem I have just wasted 1 year of my life developing something undevelopable (is that a word?). Any Help you can give me would greatly be appricated. Thank you in advance. I have one array, called for example $MainImages : - Code: [Select] Array ( [0] => Array ( [widgetID] => 143 [image] => image_a.jpg ) [1] => Array ( [widgetID] => 147 [image] => image_b.jpg ) [2] => Array ( [widgetID] => 73 [image] => image_c.jpg ) ) and a second array, we'll call it $widgets: - Code: [Select] Array ( [0] => Array ( [widgetID] => 147 [seo_title] => An excellent class B Widget [name] => Widget B [categoryID] => 1 ) [1] => Array ( [widgetID] => 73 [seo_title] => An excellent class C Widget [name] => Widget C [categoryID] => 1 ) [2] => Array ( [widgetID] => 143 [seo_title] => An excellent class A Widget [name] => Widget A [categoryID] => 1 ) ) I want to merge the value from the [][image] key from the first array into a new [][image] key / value in the second, using a shared value as a reference...so the desired result array is: - Code: [Select] Array ( [0] => Array ( [widgetID] => 147 [seo_title] => An excellent class B Widget [name] => Widget B [categoryID] => 1 [image] => image_b.jpg ) [1] => Array ( [widgetID] => 73 [seo_title] => An excellent class C Widget [name] => Widget C [categoryID] => 1 [image] => image_c.jpg ) [2] => Array ( [widgetID] => 143 [seo_title] => An excellent class A Widget [name] => Widget A [categoryID] => 1 [image] => image_a.jpg ) ) Obviously the order is different and so they need to be merged based on the widgetID values. Also, the same widgetID may be in each array more than once. I've looked at a lot of help but can't find anything to do exactly what I need....any help would be greatly appreciated! Hi, I have Code: [Select] $to = 'rberbe2002@msn.com'; $subject = 'the subject'; $message = 'hello'; $headers = 'From: webmaster@example.com'; mail($to, $subject, $message, $headers); which works fine on a shared hosting website I have, but not on a website I have on my dedicated server. Any ideas or suggestions please? Hi,
I would like to ask if someone knows a trick to know if the script is running on a shared hosting or a vps or a dedicated server.

This topic has been moved to PHP Installation & Configuration. http://www.phpfreaks.com/forums/index.php?topic=317008.0 I implemented google's reCAPTCHA V2 on http:// on the remote apache shared server and it worked 100%. I then changed the protocol to my shared server SSL using the same PHP script as the non-SSL script. The older version of reCaptcha had an SSL 'false' to 'true' SSL parameter, whereas I can't find one for V2. I had to use htaccess to redirect the example.com to the shared SSL server https://serverid.net/example/ which works perfectly without recCAPTCHA. I incorporated reCAPTCHA V2 and the error message where the reCAPTCHA image should be shows "ERROR: Invalid domain for site key". 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 Hi, how i could do this with gdlibrary: I make image with imagecreatefrompng , and that is my pictures background. Then I add image there, and that is my bird flying in the background. that is only example, i wanna just add image to image 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! |
