# mysql_fetch_object

(PHP 3, PHP 4, PHP 5)

mysql_fetch_object -- Fetch a result row as an object

## Description

object mysql_fetch_object ( resource result [, string class_name [, array params]] )

Returns an object with properties that correspond to the fetched row and moves the internal data pointer ahead.

## Parameters

result

  The result resource that is being evaluated. This result comes from a call to mysql_query().

class_name

  The name of the class to instantiate, set the properties of and return. If not specified, a stdClass object is returned.

params

  An optional array of parameters to pass to the constructor for class_name objects.

## Return Values

Returns an object with properties that correspond to the fetched row, or `FALSE` if there are no more rows.

mysql_fetch_row() fetches one row of data from the result associated with the specified result identifier. The row is returned as an array. Each result column is stored in an array offset, starting at offset 0.

## ChangeLog

Version | Description
--- | ---
5.0.0 | Added the ability to return as a different object.

範例 1. mysql_fetch_object() example

`<?php mysql_connect("hostname", "user", "password"); mysql_select_db("mydb"); $result = mysql_query("select * from mytable"); while ($row = mysql_fetch_object($result)) { echo $row->user_id; echo $row->fullname; } mysql_free_result($result); ?>`

範例 2. mysql_fetch_object() example

`<?php $row = mysql_fetch_object($result); /* this is valid */ echo $row->field; /* this is invalid */ // echo $row->0; ?>`

## Notes

> Performance: Speed-wise, the function is identical to mysql_fetch_array(), and almost as quick as mysql_fetch_row() (the difference is insignificant).

> 注: mysql_fetch_object() is similar to mysql_fetch_array(), with one difference - an object is returned, instead of an array. Indirectly, that means that you can only access the data by the field names, and not by their offsets (numbers are illegal property names).

> 注: ��ƶǦ^����O��j�p�g���C

> 注: This function sets NULL fields to PHP `NULL` value.
