Список параметров

stmt -

-
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_ABSOLUTEorSQLSRV_SCROLL_RELATIVE. Note that the first row in a result set has index 0.

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.
Примеры
Пример #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 />";
}
?>
Примечания
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
falseand adds an error 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().
