[PHP] sorting an array of objects

[L Melville]

Hi,

Is it possible to sort a class array using array multisort, I have two items
in each class that I wish to sort by, one is a text and the other is the
first item in an array within within each class. i.e.;-

$class[$index]-text;
$class[$index]-array[0];

how can I do this?

thanks in advance
lee

[PHP] changing post variable names

[L Melville]

Hi,

I have a php page that accepts post values (ie;
./page.php?var1=0var4=5).

Now there can be posted values between var(1) and var(10) and i want to
check if they exist and also utilise them.  Is there a way of accessing
these values in a loop ie;-

for($i=1;$i=10;$i++){

// do things in here that access the vars like this
$blah = $var$i;

}


thanks
lee

[PHP] post problems

[L Melville]

Hi,

I am using post to pass information to a php script ie;-

www/mypage.phtml?var=3

on the page that is being passed the data i am testing for the occurence of
var with;-

if($var)...

this is generating a warning if var is not passed to the page, as I do not
always want to pass the data to it, how can i test for the occurence of var
and respond to it from within the called page?

thanks in advance
