<p><h2>How to Implement Array Pagination and Sorting with arsort and array_slice Functions? Detailed Tutorial and Code Examples</h2></p>
<p><p>In PHP, it’s common to encounter requirements where you need to sort array data and display it in pages. This is especially true for associative arrays where you want to sort values in descending order and then extract a subset of the results according to pagination needs for user display.</p></p>
<p><p>This article will walk you through an example that demonstrates how to use <code>arsort<span>()

Execution Result

Data on page </span><span><span>2</span></span><span>:
product_7 sales: </span><span><span>250</span></span><span>
product_4 sales: </span><span><span>200</span></span><span>
product_3 sales: </span><span><span>150</span></span><span>

Conclusion

By combining arsort() and array_slice(), you can easily implement pagination and sorting for associative arrays, meeting flexible data display needs in real-world projects. The key is to maintain the association between array keys and values to ensure no data is lost.

You can also encapsulate the pagination logic into a function that dynamically accepts the page number and items per page, making the pagination and sorting feature more reusable and versatile for different business cases.
