[PHP] Re: Problems with Arrays and print and echo

Trying to use dynamic arrays, does creat the array I want, but getting

I notice a difference between arrays used locally in a function, and
arrays used as a 'var' in a class function (all in PHP 4 atm).
Code snippet:
echo ROWS returned are: $max\n;
$this-count = $max;
while ($max--) {
$row = mysql_fetch_row($result);
$this-name[$max] = sprintf(%s, $row[0]);
$Name[$max] = sprintf(%s, $row[0]);
echo init \$this-Xame[$max] = $row[0];
echo $Name[$max] $this-name[$max]\n;
$regionID[$max] = $row[1];
$constellationID[$max] = $row[2];
$this-ID[$max] = $row[3];
printf(%d:%d/%d/%s\n,$max,$regionID[$max],$constellationID[$max],
$this-name[$max]);
}
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,
for just in case
Output (debuging):
ROWS returned are: 7
init $this-Xame[6] = 8-TFDX 8-TFDX Array[6]
6:1003/2044/8-TFDX
init $this-Xame[5] = B-E3KQ B-E3KQ Array[5]
5:1003/2044/B-E3KQ
init $this-Xame[4] = BR-6XP BR-6XP Array[4]
4:1003/2044/BR-6XP
init $this-Xame[3] = G5ED-Y G5ED-Y Array[3]
3:1003/2044/G5ED-Y
init $this-Xame[2] = O-LR1H O-LR1H Array[2]
2:1003/2044/O-LR1H
init $this-Xame[1] = UL-4ZW UL-4ZW Array[1]
1:1003/2044/UL-4ZW
init $this-Xame[0] = Y5J-EU Y5J-EU Array[0]
0:1003/2044/Y5J-EU
++
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.

Some additional debug tests.
Code:
print_r($this-name);
echo \nprint_r item 5\n;
print_r($this-name[5]);
echo \necho item 5 in quotes\n;
echo \n$this-name['5']\n;
echo \necho item 5 not in quotes\n;
echo \n$Name[5]\n;
echo \necho class item 5 not in quotes\n;
echo \n$this-name[5]\n;
exit;
Output:
Array
(
[0] = Y5J-EU
[6] = 8-TFDX
[5] = B-E3KQ
[4] = BR-6XP
[3] = G5ED-Y
[2] = O-LR1H
[1] = UL-4ZW
)
print_r item 5
B-E3KQ
echo item 5 in quotes
Array['5']
echo item 5 not in quotes
B-E3KQ
echo class item 5 not in quotes
Array[5]
==
I am particilarily interested in the differences in these two echo
statements with array variables in them. Why the difference in output?
echo \necho item 5 not in quotes\n;
echo \n$Name[5]\n;
echo \necho class item 5 not in quotes\n;
echo \n$this-name[5]\n;
