  • Fastest way to check for value existance.

    - by Itay Moav
    I have a list of values I have to check my input against it for existence. What is the faster way? This is really out of curiosity on how the internals work, not any stuff about premature optimization etc... 1. $x=array('v'=>'','c'=>'','w'=>); .. .. array_key_exists($input,$x); 2. $x=array('v','c','w'); .. .. in_array($input,$x);

  • retrieving data from memcache

    - by Adnan
    Hello, I am starting to learn the benefits of memcache, and would like to implement it on my project. I have understood most of it, such as how data can be retrieved by a key and so on. Now I get it that I can put a post with all of its details in memcache and call the key POST:123, that is OK, and I can do it for each post. But how to deal with the case when I query the table posts to get the list of all posts with their titles. Can this be done with memcache, or should this always be queried from the table?

  • All numbers that are NOT in an array under 1000

    - by baklap
    Hi, I've got this programming problem. I have number for example 1000. Now I have a number in an array, like 999. Now I need to display all numbers that are NOT in the array but are 1 to 1000; The next requirement is essential: It has to be displayed in a way that it's easy to oversee. So I was thinking, lets show: 100 200 300 400 500 600 700 800 900 910 920 930 940 950 960 970 980 990 991 992 993 994 995 996 997 998 1000 What is the best way to start programming this?

    Hi, i simply can't find a solution to my problem! The quantity field worked as it should. After a few months of programming on the whole shop, i wanted to test the quantity field and recognized that it doesn't function. I only can add one product to the cart although i typed “3” in the quantity field. I didn’t change anything in product/view.phtml and addtocart.phtml. Don't know where i have to search for this error. Maybe someone can give me a tip... greets max

  • Using Zend_Db and multiple tables

    - by Yacoby
    I have a normalized database that stores locations of files on the internet. A file may have multiple locations spread across different sites. I am storing the urls in two parts (Site.UrlStart, FileLocation.UrlEnd). The UrlEnd is the part unique to that file (for the site). Simplified Db structure: I am using Zend_Db as my ORM (If it is that), with classes for the tables inheriting from Zend_Db_Table_Abstract. The issue is that retrieving the location data (e.g. the url) requires the use of multiple tables and as far as I can make out and I would either have to use both table classes (thereby exposing my table structure) or scatter sql all over my application, neither of which sound appealing. The only solution I can see is to create a façade that acts like Zend_Db_Table_Abstract (Maybe inherits from it?) and hides the fact that the data is actually on two tables. My questions are as follows: Am I going in the right direction in creating a façade class (Are there other alternatives)? Should the facade class inherit from Zend_Db_Table_Abstract?

  • How to insert the last id from a table into another table in MySQL?

    - by James
    I want to take the id of the most recent item in a database, increment it by one and insert that new id in to another table. I tried: $select = mysql_query("SELECT id FROM tableName ORDER BY id DESC"); while ($return = mysql_fetch_assoc($select)) { $id = $return['id']; $newId = $id++; } mysql_query("INSERT INTO anotherTable (someColumn) VALUES ('$newId')"); But it didn't work. How can this be done?

  • Image not rendering in dompdf

    - by Venkat
    I am using codeIgniter and dompdf for my application for generating pdfs. The below code is the code which i am using to display an image. <div class=\"block_head\"> <h2>Image display</h2>"; $image_location = "/images/xxx.png"; $html .="<img src=\"".$image_location."\" width=\"200\" height=\"200\" /> </div>"; I tested and debugged all ways whether i am doing something wrong. Like this first i checked whether the path is wrong. This is path on the server. It's correct. I tested by echoing $html also it's showing perfectly path. When i clicked on that path image is displaying. But when i am trying to render it in pdf it's not displaying. Note: PDF is generating perfectly without image.

    - by ranhan
    I am currently trying to write some unit test against my zend framework controller. When I run the following code I receive this error: public function testListActionShouldContainListTable() { $this->loginToSystem(); $uri = $this->_uriBase . 'campaign/list'; $_SERVER["REQUEST_URI"] = $uri; $this->dispatch('/campaign/list'); $this->assertController('campaign'); $this->assertAction('list'); $this->assertQueryCount('#list',1); } CampaignControllerTests::testListActionShouldContainListTable DOMDocument::loadHTML(): ID alrt already defined in Entity, line: 36 This occurs using any of the assertQuery and assertQueryContains methods. I have searched around but am not really finding a good answer to why it won't allow me to find this html node or how to get around this error. Thanks in advance for any help!

  • After 30 seconds, update MYSQL databse

    - by Sam
    Hello everyone! I've been looking around here on SO and Googling, however I can't find anything that fits my description. What I want to do is update the database if the page has not been refreshed after 30 seconds. I want to email a person with the contents of a form {submitted by a different user} (I can do that) IF the person has NOT visited the page (I can do that) within the last 30 seconds. What I've tried to do is make the page that should be visited refresh every 30 seconds, and so I figured if I did something like after 31 seconds, edit the database (so if the refreshed page was not refreshed, the database editing would run). I'm sorry if this sounds complicated, there's probably a better way to do this, but I'm not sure how. The bigger picture is I'm trying to make a 'on-duty' sort of thing, so that if the person is not actively looking at the page, they will get emailed with whatever the contents of the form is. The page will contain a table of all the entered form results.

  • How to split the chance to display SWFs evenly among banner collection?

    - by Michael Mao
    Hi all: I am working on The ausdcf.org to try adding several banner ads in swf format to the top. Everything starts to work, but I've got several questions that need your help: The client chose not to go with Google AdManager, but prefer a "minimal approach" to do this task. What I am trying to do is sort of "mimicking" the way Google AdManager does for banners, that is, to split the chance of each particular swf to be shown to the visitor evenly among the banner collection. Definitely I can add some jQuery code to do this from client-side, a random number generator and if-else statement would work - just $.load() it! However, what if I'd like to make sure those disabled Javascript (is there any now btw?) still be able to see different swfs in each visit. Any suggestion on how to approach this? Many thanks in advance.
