hi every body ;o)

I don't know to use an array , Please help me.
In my case :
$arr = array(
'FirstName' => "Tran" ,
'LastName' => "Nguyen"
'Age' => "30" );
When i access a my array following below :
$arr[0] = "Tran 1";
$arr[1] = "Nguyen 1 ";
$arr[2] = "35";

then there're errors

Please tips to me how to access array this case.
Thanks.
