My config:
Apache 1.3.12
PHP4 RC1
Solaris 2.7
MySQL 3.22.14-gamma

The following code produces this warning:
"Warning: Supplied argument is not a valid MySQL result resource in /home/mdg1/public_html/newlook/bogus.php on line 6"

When using an older version of Apache/PHP3, the script works just fine... so I've ruled out any MySQL permission problems or other such things.

Interestingly enough, the MySQL log shows that the data *WAS* fetched from the dB, but for some reason you can't get access to the result in PHP...

The code in question:

<?php
$dbh = mysql_connect("host","username","pass");
mysql_select_db("wwwphp");
	
$sectq = mysql_query("select section,tablename from sections order by disporder",$dbh);

while ( $a = mysql_fetch_array($sectq) ) {
	print ($a["section"]."<BR>\n");
}
?>
