I'm not sure if this is the problem but it is an important point. print
"\"$text\""; does not output anything to screen, as with all prints and
echos it outputs it to html (in this case within a js function definition).

Thanks a lot for your help Sheridan,
This now appears to work ok :) but if I remove the:
print "\"$text\"";
line (as it is not required), I receive errors complaining about a
syntax
error (related to what?) and that 'text' is undefined. As this line
simply
outputs the value to screen why should this cause a problem if it is
removed?
Or could it be some other problem?
Neil
PS: Here is my updated code:
--------------------------
<html>
<head>
<title>Menus test</title>
</head>
<body bgcolor="white">
<?php
$dbhost = 'localhost';
$dbuser = 'guest';
$dbpass = 'guest';
$dbname = 'IFE';
$dbtable = 'menus';
//------ DATABASE CONNECTION --------//
mysql_connect($dbhost,$dbuser,$dbpass)
or die ("Unable to connect to database");
mysql_select_db($dbname)
or die ("Unable to select database");
$sql = "SELECT * FROM $dbtable";
$result = mysql_query($sql);
$number = mysql_numrows($result);
$i = 0;
if ($number == 0)
print "Error - No records found";
elseif ($number > 0)
{
echo "<Script Language=\"JavaScript\">\n";
echo "text = new Array(";
while ($i < $number)
{
$text = mysql_result($result, $i, "name");
$i++;
if ($i < $number)
print ",";
else
print ")\n";
}
echo "</Script>\n";
}
mysql_free_result($result);
mysql_close();
?>
</body>
</html>
