You need to do something with the result set. www.php.net/mysql-fetch-array

Hello,
I've been having extensive email conversations with people over at
MySQL.com's email list. From what I'm able to prove using myphpadmin,
my problem is not with the query, but with how PHP handles it.
All I want to do is open a text file, read in two van numbers that are
there. I want to then query a table and find out what the gross pay was
for each van.
I've set up a test model. The text file contains two van numbers and
looks like this:
1111
2222
The table contains the following:
+-------------+-----------+
| vanNumber | grossPay |
|--------------|------------|
| 1111 | 1000 |
| 1111 | 500 |
| 2222 | 100 |
| 2222 | 100 |
+-------------+-----------+
I can log into myphpadmin and execute the following query:
SELECT SUM(grossPay) FROM Nero_Daily_03 WHERE vanNumber=2222
I get a result of 200, which is the correct answer.
I can log into myphpadmin and execute the following query:
SELECT SUM(grossPay) FROM Nero_Daily_03 WHERE vanNumber=1111
I get a result of 1500, which is the correct answer.
Now, lets jump to my php code. Here is the Routine I'm trying to
accomplish:
if ($viewYearEnd)
{
$readThis = ($dir."vans.txt");
$Open = fopen ($readThis, "r") or die ("Call Roger, cannot open file
$readThis");
$vanList = file ($readThis);
fclose ($Open);
$trimmedVanOne = rtrim($vanList[0]);
$trimmedVanTwo = rtrim($vanList[1]);
$sql = "SELECT SUM(grossPay) FROM Nero_Daily_03 WHERE vanNumber=1111";
$run_sql = mysql_query($sql);
?>
<table>
<tr>
<td align="left"><?php echo $trimmedVanOne ?></td>
<td align="left"><?php echo $run_sql ?></td>
</tr>
<?php
$sql = "SELECT SUM(grossPay) FROM Nero_Daily_03 WHERE vanNumber=2222";
$run_sql = mysql_query($sql);
?>
<tr>
<td align="left"><?php echo $trimmedVanTwo ?></td>
<td align="left"><?php echo $run_sql ?></td>
</tr>
</table>
<?php
exit;
}
When I run this bit of code I get the following output:
1111 Resource id #3
2222 Resource id #4
When I should be getting:
1111 1500
2222 200
For some reason the php is not 'parsing' my query(s) correctly. Can
anyone tell me why? Please?......
Thanks,
Roger
