Organizations amass large amounts of data through user entry, lead generation, list imports, and mergers and acquisitions. If that were the case, resolving duplicates would never have been a problem. The input array is expected to be numeric keys. The Challenge of Managing Duplicate Data. The easy definition a copy of an original record is a duplicate. Unlike some of the other answers, it has the ability to remove elements based on whatever key(s) you want. With that in mind and given all of PHP's quirks, below is the solution I came up with.

For performance, each comparison should be made only once.

For scalability, modify the array in place no copying to a new array.

I've given this problem a lot of thought and have determined that the optimal solution should follow two rules. $input = array_map("unserialize", array_unique(array_map("serialize", $input))) To revert it back to the multidimensional array, use unserialize() function. Though the array is now unique, the values looks like byte stream representation. Step 3: Revert it to the multidimensional array To make this one dimensional array unique, use array_unique() function. The result will be a one dimensional array no matter how many levels the multidimensional array has. To generate byte stream representation of all the elements, call serialize() function inside array_map() function as a callback function. serialize() function can generate byte stream representation of a value. Duplicacy is a new generation cross-platform cloud backup tool based on the idea of Lock-Free Deduplication. To convert the multidimensional array to a one-dimensional array, first generate byte stream representation of all the elements (including nested arrays) inside the array. Step 1: Convert the multidimensional array to one-dimensional array

I am explaining why we use 'serialize' and 'unserialize' in steps : That's why i want to share the reason of this with you so that it will help more people to understand the concept behind this. But every time i gave the answer, they asked me how this 'serialize' and 'unserialize' works. as a container for various reusable definitions schemas (data models). I have taken reference from your comment and it helps me.įirst of All, Thanks to for your solution. In the example below, duplicate definitions of a User object are replaced with.

You can use inheritance with it to define all your data models while avoiding code duplication.

Lots of person asked me how to make Unique multidimensional array. No need to duplicate models in SQLAlchemy and Pydantic.
