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

    説明

    sqlsrv_fetch_object(
        resource $stmt,
        string $className = ?,
        array $ctorParams = ?,
        int $row = ?,
        int $offset = ?
    ): mixed

    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.

    戻り値

    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().
