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

Array Declaration Alternative Method

Arrays can also declare as:

<?php

// define an array
$myarray[0] = 'element1';
$myarray[1] = 'element2';
$myarray[2] = 'element3'; 

print_r($myarray);
//print output Array ( [0] => element1 [1] => element2 [2] => element3 )

 // OR

// define an array
$myarray[keyname0] = 'element1'; 
$myarray[keyname1] = 'element2'; 

$myarray[keyname2] = 'element3'; 

print_r($myarray);

//print output Array ( [0] => element1 [1] => element2 [2] => element3 )

?>
