How to find the third minimum value of an array by php
Today, I would like to share with you how to find the third minimum value of the array php related knowledge points, detailed content, clear logic, I believe that most people still know too much about this knowledge, so share this article for your reference, I hope you can learn something after reading this article, let's take a look at it.
Methods: 1, use array_values () to convert the array into an indexed array, syntax "array_values (original array)"; 2, use sort () to sort the array in ascending order, syntax "sort (indexed array)", when the element with an index of 2 is the third minimum value; 3, use the "indexed array name [2]" statement to get.

The method of finding the third minimum of Array by php
In PHP, the array is sorted in ascending order so that the small value comes first and the large value comes last. The first three values (a [0], a [1], a [2]) are the first, second, and third small values. Take out the element with index 2 (a [2]).
Here are the specific steps.
1. Convert an array to an indexed array
Using array_values () to get the values of all the elements in the array, you can convert the associative array into an indexed array, ensuring that the array is indexed. (in this way, the third minimum value can be extracted later using the index value.)
2. Sort the indexed array in ascending order
Use the sort () function to sort the array in ascending order, so that the array elements are sorted from small to large.
Sort ($value); var_dump ($value)
At this point, the first third element, with an index of 2, is the third minimum value required.
3. Get the third minimum value
You only need to use the form of "array name [2]" to get the third element after sorting.
The third lowest value of the echo array is:. $value [2]
