# mysqli_fetch_fields

(PHP 5)

mysqli_fetch_fields

(no version information, might be only in CVS)

result->fetch_fields -- Returns an array of objects representing the fields in a result set

## Description

Procedural Style:

mixed mysqli_fetch_fields ( object result)

Object oriented style (method):

class result {
mixed fetch_fields ( void )
}

This function serves an identical purpose to the mysqli_fetch_field() function with the single difference that, instead of returning one object at a time for each field, the columns are returned as an array of objects.

## Return values

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

Tabela 1. Object properties

Property | Description
--- | ---
name | The name of the column
orgname | Original column name if an alias was specified
table | The name of the table this field belongs to (if not calculated)
orgtable | Original table name if an alias was specified
def | The default value for this field, represented as a string
max_length | The maximum width of the field for the result set.
flags | An integer representing the bit-flags for the field.
type | The data type used for this field
decimals | The number of decimals used (for integer fields)

## Example

Exemplo 1. Object oriented style

`<?php
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
$query = "SELECT Name, SurfaceArea from Country ORDER BY Code LIMIT 5";
if ($result = $mysqli->query($query)) {
/* Get field information for all columns */
$finfo = $result->fetch_fields();
for ($i=0; $i < count($finfo); $i++) {
printf("Name: %s\n", $finfo[$i]->name);
printf("Table: %s\n", $finfo[$i]->table);
printf("max. Len: %d\n", $finfo[$i]->max_length);
printf("Flags: %d\n", $finfo[$i]->flags);
printf("Type: %d\n\n", $finfo[$i]->type);
}
$result->close();
}
/* close connection */
$mysqli->close();
?>`

Exemplo 2. Procedural style

`<?php
$link = mysqli_connect("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
$query = "SELECT Name, SurfaceArea from Country ORDER BY Code LIMIT 5";
if ($result = mysqli_query($link, $query)) {
/* Get field information for all columns */
$finfo = mysqli_fetch_fields($result);
for ($i=0; $i < count($finfo); $i++) {
printf("Name: %s\n", $finfo[$i]->name);
printf("Table: %s\n", $finfo[$i]->table);
printf("max. Len: %d\n", $finfo[$i]->max_length);
printf("Flags: %d\n", $finfo[$i]->flags);
printf("Type: %d\n\n", $finfo[$i]->type);
}
mysqli_free_result($result);
}
/* close connection */
mysqli_close($link);
?>`

The above examples would produce the following output:

    Name:     Name
    Table:    Country
    max. Len: 11
    Flags:    1
    Type:     254

    Name:     SurfaceArea
    Table:    Country
    max. Len: 10
    Flags:    32769
    Type:     4
