PHP rename the keys of an array

Question

How can I rename keys in an array?

Start with this array named $start_array,

[0] => 
      [date] => 2012-05-01
      [revenue] => 100
[1]          


        

Answer 1

Old name of the key of array is 'name' and new name is 'new_name'

$myrow=array('name'=>'Sabuj'); 
$myrow['new_name']=$myrow['name'];
unset($myrow['name']);
print_r($myrow);

Result: Array ( [new_name] => 'Sabuj' )
