I was wanting to know how I get the last two ids from the table based on certain conditions for example, if today is 1st July, I want to get the id of record for today and then the id of the record before this. Please note that the id for the previous record might be different, as this is sorted by date, so previous_id = current_id - 1...

Hello. Assume I declared an Array isFind[] like this, bool[] isFind = new bool[5]; for (int i = 0; i < 5; ++i) { isFind[i] = init(); // initialize isFind[] } bool init(); { ...; // some code here } Is there any quick method (less typing code) to detect there is false element or not in isFind[]? I don't want to for/foreach Loo...
Hi! Assume we have an array of length N where the subarrays from 0 to N/2 and N/2 to N elements are sorted. Is it possible to sort the whole array using constant memory in O(N) time? Example of an array: 10, 20, 30, 40, 1, 2, 35, 60 ...

What does $_GET return when the index is not set? (Couldn't find anything in php manual about $_GET.) I wrote this to check, if the $_GET['id'] isset - and if it is not, set $id to false: <?php $id = (isset($_GET['id'])) ? $_GET['id'] : false ?> ...
Hey all, In the below javascript, "this" refers to Car object and search_id refers to the input text field with an id of "search_input". So basically the user types in text in the field and a search occurs based on the input. Now I understand that the val() method is grabbing the user input string from the input field. However, I am not...
So I'm setting up a system that has a lot of emails, and variable replacement within it, so I'm writing a class to manage some variable replacement for templates stored in the database. Here's a brief example: // template is stored in db, so that's how this would get loaded in $template = "Hello, %customer_name%, thank you for contact...
In my database, some field settings are serialized and stored. When I do this: print_r(unserialized($r['settings'])); I'll get this: Array ( [prefix] => [suffix] => [min] => [max] => [allowed_values] => 1|Common 2|Rare 3|Almost Extinct ) I'm trying to create an array based on the values for allowed_values like this: Array (...
I need to swap first n elements from two non repeating sequences(arrays), where n is a random integer. Seq1: 1 4 5 6 9 8 2 3 7 Seq2: 3 9 1 2 8 7 4 5 6 If n = 4 Seq1: 3 9 1 2 | 9 8 2 3 7 Seq2: 1 4 5 6 | 8 7 4 5 6 Now i need to repair the sequence by replacing the repeated numbers after '|'. How to do this? This is my effort.. for...
I thought that if a C# array held reference types it would simply hold references to each of the objects, however the code below tells me otherwise. It appears as if the array is holding a reference to an object of which I thought was set to be garbage collected. I feel like i'm missing something fundamental here. Can anyone tell me w...
I am using CURL to post an array. It didn't work without using http_build_query().

Say I have an array of integers: arr = [0,5,7,8,11,16] and I have another integer: n = 6 I need a function that rounds down to the nearest number from the array: foo(n) #=> 5 As you can see, the numbers do not have a fixed pattern. What's an elegant way to do this? Thanks ...
