mysql_fetch_array error

[monkeypaw201]

<?php

$con = mysql_connect("localhost","user","pass");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("my_db", $con);

$result = mysql_query("SELECT * FROM smf_messages");

while($row = mysql_fetch_array($result))
  {
echo "hi";
}
mysql_close($con);

?>

 

the error:

PHP Warning:  mysql_fetch_array(): supplied argument is not a valid MySQL result resource in test.php on line 13

[rarebit]

mysql_select_db("my_db", $con) or die(mysql_error());;

$result = mysql_query("SELECT * FROM smf_messages") or die(mysql_error());

 

see if you get any errors from these?

Or this

$con = mysql_connect("localhost","user","pass");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("my_db", $con);

$result = mysql_query("SELECT * FROM smf_messages");

while($row = @mysql_fetch_array($result))
  {
echo "hi";
}
mysql_close($con);

The query is failing. Suppressing the error will never make the code work. The cause of errors need to be found and fixed.
