Try this one..

`

$query = 'select *  from mgr.fa_elec_cash';
$stid = oci_parse($conn, $query);
oci_execute($stid);

$myfile=fopen("myFile","w") or die("Unable to open File");

$columns_total = oci_num_fields($stid);
$output = "";
for ($i = 1; $i <= $columns_total; $i++) {

   $heading = oci_field_name($stid, $i);
   $output .= '"'.$heading.'",';
}
$output .="\n";
while(($row=oci_fetch_array($stid,OCI_BOTH))!=false)
{

  for ($i = 0; $i < $columns_total; $i++) {
    $output .= '"'.$row[$i].'",';

 }
 $output .="\n";
}
oci_free_statement($stid);
oci_close($conn);
fwrite($myfile, $output);
echo "Data successfully exported";
fclose($myfile);

?>`
