use curly brackets to help PHP understand what you're after:
echo "{$this->name[5]}\n";
When you're in a string like this, PHP has a hard time knowing when
you're wanting to access a variable, and when you're simply trying to
output text. Using curly brackets clears it up.

echo "\n". $this->name[5] . " " . $this->ID[5]. "\n";
This give the same output as:
$a1 = $this->name;
$a2 = $this->ID;
echo "\n$a1[5] $a2[5]\n";
Looks like I may need to use the '.' constructor more often
Who can explain this (please)?

Line wrap is messing things up a bit.
Was trying sprintf to see if the was a buffer problem coming from mysql.
Problem seems to be the same, regardless.
Also, the names changes ($this->name[] versus $Name[]) are deliberate,

Output (debuging):
ROWS returned are: 7
init $this->Xame[6] = 8-TFDX 8-TFDX Array[6]
Is the problem that you're getting array[6] instead of the value?
Explain what you see and what you expect to see.
What is var $name originally set to, ie:
$row = mysql_fetch_row($result);
$this->name[$max] = sprintf("%s", $row[0]);
$Name[$max] = sprintf("%s", $row[0]);
Is the actual assignment of variables. What surprises me is that the
'local' variable echos what I expect, but the 'class' variable does not.
function init($id)
{
$this->ID[0] = ERROR;
$this->name[0] = "";
Hope this answers your question.
And yes, I am not happy the the 'Array[X]' output, I am expecting the
value, not what it is.
I have already tried establishing an array type early in the function...
var $name = array(); (or '' or ) ?

Thanks for your ideas, help, etc..
Maybe it is somethign as simple as "can't do that with echo", but when
the arrays are all single element ( foo_array[0] is only element ) all
statements work as expected.

Michael
