# maxdb_fetch_fields

# maxdb_result::fetch_fields

Returns an array of resources representing the fields in a result set

### Description

Procedural style

mixed maxdb_fetch_fields ( resource `$result` )

Object oriented style

mixed maxdb_result::fetch_fields ( void )

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.

### Return Values

Returns an array of resources which contains field definition information or `FALSE` if no field information is available.

Object properties
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)

### Examples

Example #1 Object oriented style

`<?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);
printf("Type: %d\n\n", $val->type);
}
$result->close();
}
/* close connection */
$maxdb->close();
?>`

Example #2 Procedural style

`<?php
$link = maxdb_connect("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($link, $query)) {
/* Get field information for all columns */
$finfo = maxdb_fetch_fields($result);
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);
printf("Type: %d\n\n", $val->type);
}
maxdb_free_result($result);
}
/* close connection */
maxdb_close($link);
?>`

The above example will output something similar to:

    Name:     NAME
    Table:
    max. Len: 10
    Flags:    -1
    Type:     2

    Name:     CNO
    Table:
    max. Len: 4
    Flags:    -1
    Type:     0
