maxdb_fetch_fields -- maxdb_result::fetch_fields — Returns an array of resources representing the fields in a result set
Stil procedural
Stil obiect-orientat
This function serves an identical purpose to the maxdb_fetch_field() function with the single difference that, instead of returning one resource at a time for each field, the columns are returned as an array of resources.
Returns an array of resources which contains field definition information or FALSE if no field information
is available.
| Property | Description |
|---|---|
| name | The name of the column |
| max_length | The maximum width of the field for the result set. |
| type | The data type used for this field |
| decimals | The number of decimals used (for integer fields) |

<?php
$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
$query = "SELECT name, cno from hotel.customer ORDER BY cno";
if ($result = $maxdb->query($query)) {
/* Get field information for all columns */
$finfo = $result->fetch_fields();
foreach ($finfo as $val) {
printf("Name: %s\n", $val->name);
printf("Table: %s\n", $val->table);
printf("max. Len: %d\n", $val->max_length);
printf("Flags: %d\n", $val->flags);
