Invalid argument supplied for foreach()

[humason]

I am getting this error message and it does not seem to be affecting my query. However, I would prefer not to suppress the error "Invalid argument supplied for foreach()", so I am wondering if anyone out there might know what I am doing wrong??

Thanks to whoever in advance!!!

$loop=1;

do
{
$loop++;
print "\t<tr border=1>\n";

foreach ($line as $col_value)
{

if( ($loop % 2) == 0 )
print "\t<td bgcolor=808080 align=center>$col_value</td>\n";

else
print "\t<td align=center>$col_value</td>\n";
}

}

while ($line = mysql_fetch_array($result, MYSQL_ASSOC));

print "</tr></table>";

The reason you're getting that error is because the first time the do-while loop runs, $line isn't anything so foreach() complains. Use a while loop instead of a do-while loop.
