Check if variable exist more than once in array?

由 假如想象 提交于 2019-12-07 03:52:31
问题 I want to do an if/else statement in PHP that relies on an item in the array existing more than once or not. Can you use count in in_array? to do something like: if (count(in_array($itemno_array))) > 1 { EXECUTE CODE } 回答1: Let $item be the item whose frequency you are checking for in the array, $array be the array you are searching in. SOLUTION 1: $array_count = array_count_values($array); if (array_key_exists($item, $array_count) && ($array_count["$item"] > 1)) { /* Execute code */ } array

How can I delete duplicates in MongoDb?

由 走远了吗. 提交于 2019-12-07 03:50:32
问题 I have a large collection (~2.7 million documents) in mongodb, and there are a lot of duplicates. I tried running ensureIndex({id:1}, {unique:true, dropDups:true}) on the collection. Mongo churns away at it for a while before it decides that too many dups on index build with dropDups=true . How can I add the index and get rid of the duplicates? Or the other way around, what's the best way to delete some dups so that mongo can successfully build the index? For bonus points, why is there a

Basic Hashtable algorithm - removing duplicates

由 隐身守侯 提交于 2019-12-07 02:40:04
问题 I just had an interview this morning and I was given the question "Give an algorithm for removing duplicates from a list of integers". This is a fairly standard question so I was pretty confident I could answer it. I am paraphrasing, but I said something along the lines of "You could use a hashtable. Start with the first integer and insert it into the hashtable. Then for each successive integer do a hashtable lookup to check if the integer is already in the hashtable, if not then insert it,

iOS - Linker Error, Duplicate Symbol

由 随声附和 提交于 2019-12-07 00:55:42
问题 It seems I am having an error when attempting to compile and it seems to be pointing to two files directly..MenuViewController and FirstTopViewController. I think it has something to do with my imports, as each of them is importing the other, however the error is referencing my Building object, which is barely used in it. Also, with the clang error, how do I use -v to see the invocation? Error: ld: duplicate symbol _OBJC_CLASS_$_Building in /Users/alexmuller/Library/Developer/Xcode

git wants to add already tracked files

由 谁说我不能喝 提交于 2019-12-06 15:43:21
I have a repository on a pc with approximate size of 70GB and when I copied it (not clone, just simple copying) to my mac it shows that some files are untracked while they are already tracked. When I added them, they appeared to be duplicated in the repo objects info but not in the working tree of course. So I made a hard reset to the last commit but the files appeared again as untracked. How can I solve this problem? (knowing that the repo on the pc is working well) Don't copy a repository's working directory from computer to computer. Problem Your working directory has checked out files in

How to identify duplicate records with a plugin in Dynamics CRM 2011

由 亡梦爱人 提交于 2019-12-06 15:39:39
I am looking to design some logic inside of my create plugin for the entity 'account'. What it does is basically check account Names and identifies account names which are duplicates on creation. So if there is an account Name, Barclays for example, and I try to create this again I'm going to alert the user with an error message that this has been created before and prevents this record from being added. public void Execute(IServiceProvider serviceProvider) { var context = (IPluginExecutionContext)serviceProvider.GetService(typeof(Microsoft.Xrm.Sdk.IPluginExecutionContext)); if (context
