There are different sorting functions used to sort the arrays and other variables. Some of the their functions are listed below:
sort() – used to sort an array in normal order
rsort() – used to sort an array in normal reverse order
asort() – used to sort array and maintain the index association(key value pair maintains even after sorting)
arsort() – same as asort() but in reverse order
ksort() – used to sort an array by its keys….
The above script displays the fruits array in normal order and also in sorted order…. simply replace the sort function with other sort functions and may see the results.
for key value, change the fruits array like the following script
$fruits=array(10=> “Orange”, 100=> “Mango”, 1000=>”Banana”);
and use the functions ksort, asort and arsort () and see that the key value pair is unchanged…..
