array keys not working

I am trying to assign keys to an associative array, but the keys are being rejected.

This works:

$myarray = array();
$key = "row_1";
$val = "some value";
$myarray = array_merge($myarray,array($key=>$val));

However, this does not:

$i = 1;
$myarray = array();
$key = "row_".$i;
$val = "some value";
$myarray = array_merge($myarray,array($key=>$val));

The only difference is how I set the value of $key.

It makes no sense. Any help would be appreciated.

Thanks

Hi,

I am not sure but.. eh.. is $i not a integer variable? Can you combine these with string variables??
Maybe that's the problem?

try adding:
$i = (string)$i;

Thanx,

Just tried:

$str = (string) $i;
$key = "row_".$str;

Tried these keys:

Key: row_1
Key: row_2
Key: row_3
Key: row_4
Key: row_5

But actual keys are returned as:

Key: 0
Key: 1
Key: 2
Key: 3
Key: 4

Any other ideas? I'm stuck ...

Try:

$key ="row_";
&key .="$str";
