Описание

Procedural Style:

mixed maxdb_fetch_fields ( resource $result )

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.

Возвращаемые значения

Object properties

<?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();
?>

Пример #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 examples would produce the following output:

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

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