Sort Array

As discussed in previous example about B.I.F (built in functions) php also have some bif for sort an  array:

• sort() - sort arrays in ascending order
• rsort() - sort arrays in descending order
• asort() - sort associative arrays in ascending order, according to the value
• ksort() - sort associative arrays in ascending order, according to the key
• arsort() - sort associative arrays in descending order, according to the value
• krsort() - sort associative arrays in descending order, according to the key.

Method to use them:

 declare array first , write method which one want to use eg:

sort($arrayname);

it will sort array in ascending order
