[something else]

something on the lines of:

$sql = mysql_query"SELECT name, COUNT(ref) AS NumOccurrences FROM users GROUP BY ref HAVING (COUNT(ref)>0)");
while($list = mysql_fetch_array($sql)){
echo $list[0].'='.$list[1];
} 

[slowy]

something on the lines of:

$sql = mysql_query"SELECT name, COUNT(ref) AS NumOccurrences FROM users GROUP BY ref HAVING (COUNT(ref)>0)");
while($list = mysql_fetch_array($sql)){
echo $list[0].'='.$list[1];
} 

i putted dis

<?php 
include ("header.php");
$sql = mysql_query'SELECT 'name',COUNT(ref) AS NumOccurrences FROM 'users' GROUP BY 'ref' HAVING (COUNT(ref)>0)';
while($list = mysql_fetch_array($sql)){
echo $list[0].'='.$list[1];
}
?>

Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING in /home/abc/public_html/aaaa.php on line 3


after that i putted

<?php 
include ("header.php");
$sql = "SELECT name, COUNT(ref) AS NumOccurref FROM users GROUP BY ref HAVING (COUNT(ref)>0)";
while($list = mysql_fetch_array($sql)){
echo $list[0].'='.$list[1];
}
?>

but
Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /home/abc/public_html/aaaa.php on line 4

Added after 33 minutes:

now i putted
dis,every thing is fine but not giving data what i want

<?php 
include ("header.php");
$sql = "SELECT name, COUNT(ref) AS NumOccurrences FROM users GROUP BY ref HAVING (COUNT(ref)>0) LIMIT 0, 5;";
$sites=MySQL_Query($sql);
while($list = mysql_fetch_array($sites))
{
echo $list[0].'='.$list[1];
echo "<br />";
}
?>

[something else]

if the last 1 is working just get rid of the limit 0, 5;
as u will be only displaying 5 results

SELECT field FROM table ORDER BY field DESC and put it on while loop.
