php program Code Explanation :
In this statement “$var1” variable is defining an associative array using array function with its keys such as “Lemon, Apple and Grape” and the values as “34,50, and 25”.
The var1 value will be sorted using the krsort function where the array keys are sorted in ascending order.
In this statement we use the for each loop that will be used for looping process in an associative array. The first variable of the for loop defines the array name “$var1” then “$x” defines the key, and “$x_value” defines the value.
Echo statement is used to print the value of the sorted key and their values. Whereas, the “.” Dot symbol is used for concatenation of the string in php.
php coding Sample Output :
Output shows the keys (Lemon, Apple and Grapes) are sorted in descending order (Lemon, Grapes and Apple) according to the values with its keys (34,25 & 50) as it is.
