What's wrong with these code?

Anon

$meta[0] = "001";
for ($j=0; $j<=count ($meta); $j++){
$query = "select ic_no from mem_data where sp_ic = '$meta[$j]'";
$result = mysql_query($query);
while ($row = mysql_fetch_array($result)) {
$meta[] = $row["ic_no"];
$children[] = $row["ic_no"];
}
$children2 = $children;

$child = array ( $meta[$j] => array $children2) ); //Main Problem, it's an associative array

Unset ($children);
}
}

reset ($child);
while (list($key,$value) = each ($child)){
echo "Parent: $key ;Child:$value \n";
}//Primary print method

/foreach ( $child as $key ){
echo " ",$key, " ",$val," ";
echo "parent2:W";
}///Alternative print method

(Both of the print method return me a blank page including this one

foreach ( $child as $key=>$val ){
echo $key, " ";
foreach ($val as $val2){
echo "-->",$val2;
}
}
what is the problem? And it's there any guide to talk about associative array?)

Thanks for your assistance and good day.

Are you sure your Query returns result?

Right after your $query =[..] try putting:

echo "$query";

Perhaps you'll see your problem in the actual query that is send.

Also, after your while loop you could put:

echo "" . $row["ic_no"] . "";

Just to see what's been queried, and what's being returned.

Perhaps:
http://www.php.net/manual/language.types.array.php

Might tell you something, alot of people annotated this manual location.

I have try the way suggested by Martin. i can print out the query and i get the result from the query. So the problem is not on the query. I think the problem lies on the way i populate the associative array,
1)
$child = array ( $meta[$j] => array $children2) ); //Main Problem, it's an associative array

or the way i print it
2)
foreach ( $child as $key ){
echo " ",$key, " ",$val," ";
}

but i think the first one is the mistake i made, can anyone suggest me a correct way to do it?

thanks for your assistance and good day.
