Now $field is an array full of your column names. Adapt to your needs.

RE: [PHP-DB] Extracting result - unknown number of fields
OK, please ignore, I believe I've found the answer in the manual notes:
$query="your SQL";
$result=mysql_query($query) or die("Query ($query) sucks!");
$fields=mysql_num_fields($result);
echo "\n";
for ($i=0; $i < mysql_num_fields($result); $i++) //Table Header
{ print "".mysql_field_name($result, $i).""; }
echo "\n";
while ($row = mysql_fetch_row($result)) { //Table body
echo "";
for ($f=0; $f < $fields; $f++) {
echo "$row[$f]"; }

Maybe mysql_num_fields() and mysql_field_name() will be of use, here? Check
the manual..

Calculate the value for mysql_num_fields() outside of your for() loop to
improve effeciency.
$num_fields = mysql_num_fields($result);
for($i=0; $i < $num_fields; $i++) // Table Header
{ print "".mysql_field_name($result, $i).""; }

[PHP-DB] Extracting result - unknown number of fields
While doing a cross tabulation, I've got a query which gives me a variable
number of fields:
$query="SELECT Dept";
$count=count($piv_cos);
for($x=0;$x<$count;$x++){
$query.=", SUM(IF(Co='$piv_cos[$x]',Exps175,0)) AS '$piv_cos[$x]'";
}
$query.=" FROM $tbl1 GROUP BY Dept";
$result=mysql_db_query($db, $query, $connection) or die ("Query9
failed: $query");
...but how do I extract?
$piv_depts=array();
for($x=0;$x<$count;$x++){${piv_.$x}=array();}
$piv_dept1=array();
$x=0;
while(list($a,$b)= mysql_fetch_array($result)) //I DON'T KNOW HOW
MANY TO list()
{
$piv_cos[$x]=$a;
for($y=0;$y<$count;$y++){${piv_.$y}[$x]=$b;}
//...
//...
//$piv_dept1[$x]=$b;
$x++;
}
Is there an alternative approach?
Thanks,
John
