how can i get [user_id] from this array? Array ( [2] => cbpaidSubscription Object ( [replaces_plan] => [replaces_subscription] => [subscription_date] => 2009-07-14 12:45:52 [last_renewed_date] => 2009-07-14 12:45:52 [expiry_date] => 2010-07-14 12:45:52 ...
Hey everyone, I am trying to compare to multidimentional arrays, but I can't just use array_diff_assoc(). The arrays I am trying to compare are both associative arrays, and they are both sorted so the keys are in the same order. For the most part the arrays are identical in structure. I can't seem to figure out how to compare the ele...
...without using typedef. My boss claims he was once asked this in an interview, and when he gave his answer the interviewers told him he couldn't use typedefs because it was poor style. Regardless, he likes to throw the question out at people just to see if they can get it right , usually at new programmer lunches. No one ever gets ...
I have this multi-dimensional PHP array (below). Array ( [0] => Array ( [2] => [email protected] ) [1] => Array ( [4] => [email protected] ) [2] => Array ( [3908] => [email protected] ) [3] => Array ( [2548] => eleve...
Hey Guys, I have a function that returns a 2 dimensional array. Due to the nature of the program I MUST declare it as an object. Like this object o1 = function(x); //note the function returns something similar to this {string[x,y]}; ultimately I want to bind this data to a GridView. If the array is one dimensional...the followi...
Consider a matrix M and a set of subscripts stored in columns I and J. I need to access the elements designated by I & J without converting them to linear indices (i.e. using sub2ind). E.g. M = [1 2 3;4 5 6;7 8 9]; I = [1 1 1]; J = [1 2 3]; VALS = [1 2 3]; Also, doing the following is not feasible since I & J are huge : VALS = diag(...
I have to use a method which accepts double[,], but I only have a double[]. How can I convert it? Solution so far: var array = new double[1, x.Length]; foreach (var i in Enumerable.Range(0, x.Length)) { array[0, i] = x; } ...
Hello, I'm building a script which will open a saved text file, export the contents to an array and then dump the contents in a database. So far I've been able to get the file upload working quite happily and can also open said file. The trouble I'm having is the contents of the file are variable, they have a fixed structure but the co...
Hi, I'm trying to run over the parameters space of a 6 parameter function to study it's numerical behavior before trying to do anything complex with it so I'm searching for a efficient way to do this. My function takes float values given a 6-dim numpy array as input. What I tried to do initially was this: 1) First I created a functio...
I need to explode by "," then ":". Easy enough... $alttitle = "35:title1,36:title2, 59:title5" $replacetitles = explode(",",$alttitle); for ($i = 0 ; $i < count($replacetitles) ; $i++) { $replacetitle[] = explode(":", $replacetitles[$i]); } Which produces... Array ( [0] => Array ( [0] => 35 [1] => title1 ) [1] => Array ( [0] => 36...
How can you do this? My code seen here doesn't work for($i=0;i<count($cond);$i++){ $cond[$i] = $cond[$i][0]; } ...
I have an array of an unknown length which will always have an evenly divisible amount of values, for example: print_r($initialarray); Array ( [0] => 30 [1] => 31 [2] => 32 [3] => 33 [4] => 34 [5] => 35 ) I need to create sets: Set 1: 30 v 35; 31 v 34; 32 v 33; Set 2: 30 v 34; 31 v 33; 32 v 35; Set 3: 30 v 33; 31 v 32; 34 v 3...
Well the title sucks. But here is what I am trying to do. I have a foreach loop that is already pulling all the rows from a mysql db table using a db object style query in a function. That function is grabbing all fields and setting it up in an array ex foreach ($blahs as $blah => $blah_data) That now allows me to populate the page w...
Hello I have an array which for arguments sake looks something like this: a = [[1,100], [2,200], [3,300], [2,300]] Of those four sub-arrays, I would like to merge any where the first element is a duplicate. So in the example above I would like to merge the 2nd and the 4th sub-arrays. However, the caveat is that where the second eleme...
I have an array of float rtmp1[NMAX * 3][3], and it is used as rtmp1[i][n], where n is from 0 to 2, and i is from 0 to 3 * NMAX - 1. However, I would like to convert rtmp1 to be rtmp1[3 * 3 * NMAX]. Would addressing this new 1D array as rtmp1[3 * i + n] be equivalent to rtmp1[i][n]? Thanks in advance for the clarifications. ...
I am trying to determine if the an element in one multi-dimensional array exists in another similarly structured array. suspects = [['Rod', 100], ['Jane', 75], ['Freddy', 125]] criminals = [['Bill', 75], ['Ted', 50], ['Rod', 75]] The response I am looking for is either true or false. In the example above the response would be true bec...
I am fairly new at object oriented programming (but am starting to pick up fairly quickly), and am working on an application for the iphone. I need to make a multidimensional array, (10,000 or more rows, 8 collums) ordered as such:3 collums should contain boolean values, one should contain an integer, two need to hold GPS coordinates (us...
