wrong ouputs with php and mysql!!

ok below i have the following php code
im trying to match up to tables so i get a better and more descriptive output
rg instead of and number "80" i want to output " port http-web"

i thought i had it with the mysql statement below
but ouputs are wrong like they dont match at all

Domain Name Server 69
Domain Name Server 53

PHP Code:




$sql2=( "SELECT services.description FROM services,udphdr WHERE services.port = udphdr.udp_dport"); 
$result2 = mysql_query($sql2) or die(mysql_error()); 
$myrow2 = mysql_fetch_array($result2); 
 
 
echo"<table BORDER='2' CELLPADDING='5' align ='center'>"; 
echo"<caption>UDP Header Details</caption>"; 
echo"<th>Sensor ID:</th><th>CID:</th><th>UDP Source Port:</th><th>UDP Destination Port:</th><th>UDP Length:</th><th>UDP Checksum</th>"; 
 
do { 
      
        printf("<tr bgcolor=\"white\"><td>%s</td><td> %s</td><td>%s %s</td><td> %s %s</td><td> %s</td><td>%s</td></tr>", $myrow["sid"], $myrow["cid"], $myrow1["description"],$myrow["udp_sport"], $myrow2["description"], $myrow["udp_dport"], $myrow["udp_len"],  $myrow["udp_csum"]); 
         
 
 
      } while (($myrow = mysql_fetch_array($result)) 
    &&($myrow1 = mysql_fetch_array($result1))&&($myrow2 = mysql_fetch_array($result2)));

so anybody know whats up with this ??

Hard to say without knowing the other 2 SELECTs...

Code:

$sql = ("SELECT  * FROM udphdr ");

$result = mysql_query($sql) or die(mysql_error());

$myrow = mysql_fetch_array($result);



$sql1=( "SELECT services.description FROM services, udphdr WHERE services.port = udphdr.udp_sport");

$result1 = mysql_query($sql1) or die(mysql_error());

$myrow1 = mysql_fetch_array($result1);



$sql2=( "SELECT services.description FROM services,udphdr WHERE services.port = udphdr.udp_dport");

$result2 = mysql_query($sql2) or die(mysql_error());

$myrow2 = mysql_fetch_array($result2);





echo"<table BORDER='2' CELLPADDING='5' align ='center'>";

echo"<caption>UDP Header Details</caption>";

echo"<th>Sensor ID:</th><th>CID:</th><th>UDP Source Port:</th><th>UDP Destination Port:</th><th>UDP Length:</th><th>UDP Checksum</th>";



do {

        

        printf("<tr bgcolor=\"white\"><td>%s</td><td> %s</td><td>%s %s</td><td> %s %s</td><td> %s</td><td>%s</td></tr>", $myrow["sid"], $myrow["cid"], $myrow1["description"],$myrow["udp_sport"], $myrow2["description"], $myrow["udp_dport"], $myrow["udp_len"],  $myrow["udp_csum"]);

                





      } while (($myrow = mysql_fetch_array($result))

        &&($myrow1 = mysql_fetch_array($result1))&&($myrow2 = mysql_fetch_array($result2)));

ok there are the other 2 select statement, hope it helps

The results of the queries have no 'link' between them and the three results are correct, but they can go in any order. I think there can be only one SELECT used, but I don't understand the meaning fully so I don't know how to write it. COuld you explain what you'd like to get exactly (what should be the connections between results of the three queries)?

well one of the statements just outputs all info from a database while the other 2 are doing the same thing as each other.

i want to match up data in the udphdr table with the services table (both in the same database)

instead of getting an output of lets say 80 i want to take that 80 and match it up with what the services tables says what 80 represents via the field description

i kinda know why i have to only use one select statement thought by doing it this way would work too but how do i go about using one select statement

i think if i do some kind of order in them i might be able to match and link them up what do ye think!?

I think that the query may be

Code:

SELECT udphdr.cid, udphdr.sid, udphdr.udp_sport, udphdr.udp_dport,

            udphdr.udp_len, udphdr.udp_csum sdesc.description, sdest.description

FROM udphdr, description AS sdesc, description AS sdest

WHERE sdesc.port=udphdr.udp_sport AND sdest.port=udphdr.udp_dport

Not tested, you should check if mysql allows you to run such a query, but I don't see any reason it shouldn't.
