  • PHP array minor problem

    - by Sennheiser
    I'm really not sure how to explain this. It's so simple I can't fathom why it's not working. I have a loop. It puts a bunch of strings into an array. If I fill a single variable with any given string, it will output it perfectly. But filling an array with the strings will make it give me the dreaded: Array Array Array Array Array Array Array Array Note: my strings are not all 'Array'. The way I loop is: while(...) { $arr[] = $resultFromLoop; } Here is my var_dump. array(1) { ["tagName"]=> string(5) "magic" } array(1) { ["tagName"]=> string(4) "nunu" } array(1) { ["tagName"]=> string(5) "books" } array(1) { ["tagName"]=> string(0) "" } array(1) { ["tagName"]=> string(3) "zzz" } array(1) { ["tagName"]=> string(4) "grey" } array(1) { ["tagName"]=> string(3) "new" } array(1) { ["tagName"]=> string(6) "flight" }

  • Summary statistics in visual basic

    - by ben
    Below I am trying to write a script the goal of which is to calculate some summary statistics for a few different columns of numbers. I have gotten some help on it up to the "Need help below" mark. But beyond that I am flabergasted as to how to calculate the simple stats (sum, mean, standard deviation, coefficient of variation). I know VB has scripts for these stats, which I have included in my code, but I guess I need to do some extra declaring or something. Advice much appreciated. Thanks.

  • PHP - Search array in array

    - by Anonymous2011
    I have tried googling for the past one hour straight now and tried many ways to search for an array, in an array. My objective is, to find a keyword in the URL, and the keywords are in a txt file. This is what i have so far - but doesn't work. $file = "keywords.txt"; $open = fopen($file,'r'); $data = fread($open,filesize($file)); $data = explode(" ",$data); $url = (!empty($_SERVER['HTTPS'])) ? "https://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'] : "http://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI']; $url = parse_url($url); //parse the URL into an array foreach($data as $d) { if(strstr($d,$url)) { echo "yes"; } } This works WITHOUT the text file, or array - but that's not what i want. I'd appreciate it if anyone can assist me.

  • [FLEX 3] Placing images into a Collage Canvas

    - by Bridget
    I've got an array of different sized images. I want to place these images on a canvas in a sort of automated collage. Does anyone have an idea of how to work the logic behind this concept? All my images have heights divisible by 36 pixels and widths divisible by 9 pixels. They have mouseDown functions that allow you to drag and drop. When dropped the image goes to the closest x point divisible by 9 and y point divisble by 36. There is a grid drawn on top of the canvas. I've sorted the array of images based on height, then based on their widths. imagesArray.sortOn("height", Array.NUMERIC | Array.DESCENDING); imagesArray.sortOn("width", Array.NUMERIC | Array.DESCENDING); I'd like to take the largest image ( imageArray[0] ) to put in corner x,y = 0,0. Then randomize the rest of the images and fit them into the collage canvas.

    I have the following select list: <form action="mail.php" method="POST"> <select name="foo" id="foo"> <option value="sales">Sales</option> <option value="salesAssist">Sales Assist</option> <option value="billing">Billing</option> <option value="billingAssist">Billing Assist</option> </select> </form> I need to route the $mailTo variable depending on which option they select, Sales and Sales Assist go to [email protected], while Billing and Billing Assist go to [email protected] PHP pseudeo code! <? php $_POST['foo'] if inArray(sales, salesAssist) foo="[email protected]"; else if inArray(billing, billingAssist) foo="[email protected]"; mailTo="foo" ?> I know there is nothing correct about the above, but you can see what I am trying to do, change a variable's value based on the selected value. I don't want to do this with JS, would rather learn more PHP here. Thank you.

  • Resize Array By Last and not by First in C#

    - by Leen15
    Hi all! I have an Array of Class elements, and by an int variable i need to resize this array to the last X elements. So for example i have an array with: Array[0] = Msg1 Array[1] = Msg2 Array[2] = Msg3 Array[3] = Msg4 Array[4] = Msg5 Array[5] = Msg6 Array[6] = Msg7 Array[7] = Msg8 Array[8] = Msg9 Array[9] = Msg10 and i need to have only the last 8 elements in the array. i cannot use the Array.Resize function because the result would be: Array[0] = Msg1 Array[1] = Msg2 Array[2] = Msg3 Array[3] = Msg4 Array[4] = Msg5 Array[5] = Msg6 Array[6] = Msg7 Array[7] = Msg8 and i need something like this: Array[0] = Msg3 Array[1] = Msg4 Array[2] = Msg5 Array[3] = Msg6 Array[4] = Msg7 Array[5] = Msg8 Array[6] = Msg9 Array[7] = Msg10 How can i do this? i hope my problem is clear. Thanks.

  • jquery to create array from form data

    - by AndrewStevens
    I've been wrestling with this problem for a couple hours now. Essentially, what I need to do is take the following or similar HTML: <div id="excpdivs"> <div class="excpdiv" id="excpdiv0"> Date: <input name="excp[0][date]"> Open: <input name="excp[0][open]"> Close: <input name="excp[0][close]"> </div> <div class="excpdiv" id="expdiv1"> Date: <input name="excp[1][date]"> Open: <input name="excp[1][open]"> Close: <input name="excp[1][close]"> </div> and get an array similar to the following to a php script: Array ( [0] => Array ( [date] => 2012-09-15 [open] => 3:00 [close] => 5:00 ) [1] => Array ( [date] => 2012-09-16 [open] => 2:00 [close] => 5:00 ) ) My main problem is getting the values from the input elements. My latest attempt is the following: var results = []; $(".excpdiv").each(function(){ var item = {}; var inpts = $(this).find("input"); item.date = $(inpts.get(0)).val(); item.open = $(inpts.get(1)).val(); item.close = $(inpts.get(2)).val(); results.push(item); }); Am I on the right track or am I hopelessly lost?

  • How do I generate an Array string from an array in memory (php).

    - by Itay Moav
    I need to create a big array in my code, I have the values in several tables (for easy management). I select it and now I have all the values in an array, in memory in the way I want. My problem, I need to write this array down, into the code. Is there a way to take an array which sits in the memory and translate it into a string "array('g'='h','b'='d'....)" which I can then echo and just copy-paste into my code?

  • undo or reverse argsort(), python

    - by Vincent
    Given an array 'a' I would like to sort the array by columns "a.sort(axis=0)" do some stuff to the array and then undo the sort. By that I don't mean re sort but basically reversing how each element was moved. I assume argsort() is what I need but it is not clear to me how to sort an array with the results of argsort() or more importantly apply the reverse/inverse of argsort() Here is a little more detail I have an array a, shape(a) = rXc I need to sort each column aargsort = a.argsort(axis=0) # May use this later aSort = a.sort(axis=0) now average each row aSortRM = asort.mean(axis=1) now replace each col in a row with the row mean. is there a better way than this aWithMeans = ones_like(a) for ind in range(r) # r = number of rows aWithMeans[ind]* aSortRM[ind] Now I need to undo the sort I did in the first step. ????

  • Removing “duplicate objects” with same attributes using Array.map

    - by keruilin
    As you can see in the current code below, I am finding the duplicate based on the attribute recordable_id. What I need to do is find the duplicate based on four matching attributes: user_id, recordable_type, hero_type, recordable_id. How must I modify the code? heroes = User.heroes for hero in heroes hero_statuses = hero.hero_statuses seen = [] hero_statuses.sort! {|a,b| a.created_at <=> b.created_at } # sort by created_at hero_statuses.each do |hero_status| if seen.map(&:recordable_id).include? hero_status.recordable_id # check if the id has been seen already hero_status.revoke else seen << hero_status # if not, add it to the seen array end end end

  • More compact way to do this?

    - by Macha
    I have a couple of functions that loop around the surrounding cells of a cell. The grid is contained inside an array. In my code, I have checks to make sure it's not one of the edge cells, as checking an undefined cell causes an error. As such, I have code like this: if(x > 0) { var firstX = x - 1; } else { var firstX = x; } if(x < 199) { var lastX = x + 1; } else { var lastX = x; } if(y > 0) { var firstY = y - 1; } else { var firstY = y; } if(y < 199) { var lastY = y + 1; } else { var lastY = y; } A lot of lines of code to do very little. Is there a more elegant way to do this?

  • split a string into a key => value array in php

    - by andy-score
    +2-1+18*+7-21+3*-4-5+6x29 The above string is an example of the kind of string I'm trying to split into either a key = value array or something similar. The numbers represent the id of a class and -,+ and x represent the state of the class (minimised, expanded or hidden), the * represents a column break. I can split this into the columns easily using explode which gives and array with 3 $key = $value associations. eg. $column_layout = array( [0] => '+2-1+18' , [1] => '+7-21+3' , [2] => '-4-5+6x29' ) I then need to split this into the various classes from there, keeping the status and id together. eg. $column1 = array( '+' => 2 , '-' => 1 , '+' => 18 ) ... or $column1 = array( array( '+' , 2 ) , array( '-' , 1 ) , array( '+' , 18 ) ) ... I can't quite get my head round this and what the best way to do it is, so any help would be much appreciated.

  • dojo dynamic right click context menu

    - by levy
    There are tons of different dojo right click context menus in a page slowing down the browser. Some divs have context menus while some others don't. So I just can't have a dynamic global context menu and still be able to fallback to the browser's built in menu in some cases, do I? The non lazy instantiation of the dojo context menus just take too much time. How can I make those context menus dynamic? Preferably being created on demand when the user actually right clicks on them.
