In this lesson I will show you how to sort associative arrays in PHP.
The 4 functions we will use are:
asort()
ksort()
arsort()
krsort()
Consider the following associative array containing names and ages.
The name is known as the key and the age is known as the value in the key/value pair.

We use asort() to sort the array by the value in ascending order as follows:
The output will be:
krsort()
We use krsort() to sort the array by the key in descending order as follows:
The output will be:
arsort()
We use arsort() to sort the array by the value in descending order as follows:
