• How to extract data out of a specific PHP array

  - by user77413

  I have a multi-dimensional array that looks like this: The base array is indexed based on category ids from my catalog. $categories[category_id] Each base array has two underlying elements: ['parent_category_id'] ['sort_order'] I want to create a function that allows us to create a list of categories for a given parent_category_id in the correct sort order. Is this possible? Technically it is the same information, but the array is constructed in a weird way to extract that information.

• Search and remove an element in mulit-dimentional array in php depending on a criteria

  - by Nadeem

  I've a simple question about multi-dim array, I want to remove any redundent element let's say in my case, [serviceMethod] => PL is coming 2 times, I want to search 'PL' with respect of [APIPriceTax] if an element has a lower price I want to keep it and remove the other one in array Array ( [0] => Array ( [carrierIDs] => 150 [serviceMethod] => CP [APIPriceTax] => 30.63 [APIPriceWithOutTax] 28.32 [APIServiceName] => Xpresspost USA [APIExpectedTransitDay] => 2 ) [1] => Array ( [carrierIDs] => 155 [serviceMethod] => PL [APIPriceTax] => 84.13 [APIPriceWithOutTax] => 73.8 [APIServiceName] => PurolatorExpressU.S. [APIExpectedTransitDay] => 1 ) [2] => Array ( [carrierIDs] => 164 [serviceMethod] => PL [APIPriceTax] => 25.48 [APIPriceWithOutTax] => 22.35 [APIServiceName] => PurolatorGroundU.S. [APIExpectedTransitDay] => 3 ) ) This is my pseudo code: Where $carrierAddedToList is the actual array $newCarrierAry = function($carrierAddedToList) { $newArray = array(); foreach($carrierAddedToList as $cV => $cK) { if( !in_array($cK['serviceMethod'],$newArray) ) { array_push($newArray, $cK['serviceMethod']); } } return $newArray; } ; print_r($newCarrierAry($carrierAddedToList));

• Newbie - eclipse workflow (PHP development)

  - by engil

  Hi all - this is a bit of a newbie question but hoping I can get some guidance. I've been playing around with Eclipse for a couple months yet I'm still not completely comfortable with my setup and it seems like every time I install it to a new system I end up with different results. What I'm hoping to achieve is (I think) fairly standard. In my environment I'd like SVN (currently using Subclipse), FTP support (currently using Aptana plugin), debugging (going to use XDebug) and all the usual bells and whistles of development (code completion, refactoring, etc.) My biggest current issue is how to set up my environment to support both a 'development' and 'production' server. Optimally I would be able to work directly against the dev server (Eclipse on my Vista desktop against the VM Ubuntu dev server) and then push to production server (shared hosting). I'd prefer to work directly against the dev server (with no local project files, just using the Connections provided by Aptana) but I'm guessing this won't allow for code-completoin or all the other bells and whistles provided for development. Any thoughts? Kind of an open ended question, but maybe this could be an opportunity for some of you with a great deal of experience using Eclipse to describe your setups so people like me can get some insight into good ways to get set up.

• Right align text in an image with imagettftext(), PHP

  - by James Simpson

  I am setting up dynamic forum signature images for my users and I want to be able to put their username on the image. I am able to do this just fine, but since usernames are different lengths and I want to right align the username, how can I go about doing this when I have to set x & y coordinates. $im = imagecreatefromjpeg("/path/to/base/image.jpg"); $text = "Username"; $font = "Font.ttf"; $black = imagecolorallocate($im, 0, 0, 0); imagettftext($im, 10, 0, 217, 15, $black, $font, $text); imagejpeg($im, null, 90);

• PHP: Parsing of a given form input variable

  - by Jaime Cross

  How would I go about parsing incoming form data where the name changes based on section of site like: <input type="radio" name="Motorola section" value="Ask a question"> where 'Motorola section may be that, or Verizon section, or Blackberry section, etc. I do not have any control over changing the existing forms unfortunately, so must find a way to work with what is there. Basically, I need to be able to grab both the name="" data as well as its coresponding value="" data to be able to populate the email that gets sent properly.

• Unique identification string in php

  - by NardCake

  Currently me and my friend are developing a website, for what we will call 'projects' we just have a basic auto increment id in the database used to navigate to projects such as oururl.com/viewproject?id=1 but we started thinking, if we have alot of posted projects thats going to be a LONG url. So we need to somehow randomly generate a alphanumerical string about 6 characters long. We want the chance of the string being duplicated being extremely low and of course we will query the database before assigning an identifier. Thanks for anyhelp, means alot!

• Which is more efficent PHP: array_intersect() OR array_intersect_key()

  - by Jordan Rutty

  Is it more efficient to use the key intersect or the value intersect if both key and value have the same contents for example: Array ( [743] => 743 [744] => 744 [745] => 745 [746] => 746 [747] => 747 [748] => 748 ) Is there any difference in performance in using one or the other with the same values. Similar to the difference of using double or single quotes?

• Nested Dynamic PHP Class

  - by user338844

  Alright, I may just need a terminology update, but I have been playing in Magento and Joomla, and they do references like $mage = new Mage; $mage->block('blockname'); where class Mage through some process I am failing to figure out is calling: class blockname extends something{ } Don't quote me on that code, however I am looking to do something like that where I have a file that I can do $myscript-block('blockname'); and it will load and call the file with class blockname. I hope that is not too confusing, but any help is appreciated. Thanks in advance!

• PHP Extract Values From One String Based on a Pattern Defined in Another

  - by ironkeith

  I have two strings: $first = '/this/is/a/string'; $second = '/this/:param1/a/:param2'; And I'm trying to get this: $params = array('param1' => 'is', 'param2' => 'string'); But getting from point a to b is proving more than my tired brain can handle at the moment. Anything starting with a ':' in the second string defines a variable name/position. There can be any number of variables in $second which need to be extracted from $first. Segments are separated by a '/'. Thanks.
