Notice: Undefined index: prop_id in

i write this php code

//*************************************************
<?php
require_once("Connections/connection.php");
$q_prod_prop = "select * from prop_prod";
$rs_q_prop_prod = mysql_query($q_prod_prop,$link) or die(mysql_error($link));

echo "Query :" .$q_prod_prop;
echo "<br>";
echo "<br>";
echo "Total No. of Records :".mysql_num_rows($rs_q_prop_prod);
echo "<BR>";
while($rows_rs_q_prop_prod = mysql_fetch_row($rs_q_prop_prod))
{
echo $rows_rs_q_prop_prod["prop_id"];
echo $rows_rs_q_prop_prod["prop_value"];
}
?>
//************************************************** *

But output of above php code is
//**************************************************

Query :select * from prop_prod

Total No. of Records :100

why it gives me Notice: Undefined index: prop_value in...
Plz help me thanx.... in adv..

When you use mysql_fetch_row(), a numerical index is returned, to achieve what you want you should use mysql_fetch_assoc().

or kill two birds with one stone and use mysql_fetch_Array() which will return both a numberic and associative array at negligible extra parsing to the aforementioned functions

have to disagree there, only use mysql_fetch_array() if you NEED both array types, as it is slower than mysql_fetch_assoc().
