sqlsrv_fetch_object — Retrieves the next row of data in a result set as an object

### 説明

mixed sqlsrv_fetch_object ( resource `$stmt` [, string `$className` [, array `$ctorParams` [, int `$row` [, int `$offset` ]]]] )

Retrieves the next row of data in a result set as an instance of the specified class with properties that match the row field names and values that correspond to the row field values.

### パラメータ

`stmt`

  A statement resource created by sqlsrv_query() or sqlsrv_execute().

`className`

  The name of the class to instantiate. If no class name is specified, stdClass is instantiated.

`ctorParams`

  Values passed to the constructor of the specified class. If the constructor of the specified class takes parameters, the ctorParams array must be supplied.

`row`

  The row to be accessed. This parameter can only be used if the specified statement was prepared with a scrollable cursor. In that case, this parameter can take on one of the following values:

  - SQLSRV_SCROLL_NEXT
  - SQLSRV_SCROLL_PRIOR
  - SQLSRV_SCROLL_FIRST
  - SQLSRV_SCROLL_LAST
  - SQLSRV_SCROLL_ABSOLUTE
  - SQLSRV_SCROLL_RELATIVE
`offset`

  Specifies the row to be accessed if the row parameter is set to `SQLSRV_SCROLL_ABSOLUTE` or `SQLSRV_SCROLL_RELATIVE`. Note that the first row in a result set has index 0.

### 返り値

Returns an object on success, `NULL` if there are no more rows to return, and `FALSE` if an error occurs or if the specified class does not exist.

### 例

例1 sqlsrv_fetch_object() example

The following example demonstrates how to retrieve a row as a stdClass object.

`<?php
$serverName = "serverName\sqlexpress";
$connectionInfo = array( "Database"=>"dbName", "UID"=>"username", "PWD"=>"password");
$conn = sqlsrv_connect( $serverName, $connectionInfo);
if( $conn === false ) {
die( print_r( sqlsrv_errors(), true));
}
$sql = "SELECT fName, lName FROM Table_1";
$stmt = sqlsrv_query( $conn, $sql);
if( $stmt === false ) {
die( print_r( sqlsrv_errors(), true));
}
// Retrieve each row as an object.
// Because no class is specified, each row will be retrieved as a stdClass object.
// Property names correspond to field names.
while( $obj = sqlsrv_fetch_object( $stmt)) {
echo $obj->fName.", ".$obj->lName."<br />";
}
?>`

### 注意

If a class name is specified with the optional $className parameter and the class has properties whose names match the result set field names, the corresponding result set values are applied to the properties. If a result set field name does not match a class property, a property with the result set field name is added to the object and the result set value is applied to the property. The following rules apply when using the $className parameter:

- Field-property name matching is case-sensitive.
- Field-property matching occurs regardless of access modifiers.
- Class property data types are ignored when applying a field value to a property.
- If the class does not exist, the function returns `FALSE` and adds an error to the error collection.

Regardless of whether the $className parameter is supplied, if a field with no name is returned, the field value will be ignored and a warning will be added to the error collection.

When consuming a result set that has multiple columns with the same name, it may be better to use sqlsrv_fetch_array() or the combination of sqlsrv_fetch() and sqlsrv_get_field().
