Hello
I want to sort an array using an associate key. How do I sort an array as the following:
<?php
$arr = array(
array('name' => 'Peter','age' => '32'),
array('name' => 'Norman','age' => '30'),
array('name' => 'Andy','age' => '31'),
array('name' => 'Bill','age' => '15')
);
?>
I want to sort the array key 'age', so that the output of print_r($arr) would be like the output below:
Array (
[0] => Array ( [name] => Bill [age] => 15 )
[1] => Array ( [name] => Norman [age] => 30 )
[2] => Array ( [name] => Andy [age] => 31 )
[3] => Array ( [name] => Peter [age] => 32 )
)
Many thanks.
Norman
