fetch_object

定義和用法

fetch_object() / mysqli_fetch_object()函數以對象的形式返回結果集中的當前行。

注意：從該函數返回的字段名是區分大小寫的。

實例

例子1 - 面向對像風格

返回結果集中的當前行，然後打印每個字段的值：

 <?php
$mysqli = new mysqli ( "localhost" , "my_user" , "my_password" , "my_db" ) ;

if ( $mysqli -> connect_errno ) {
  echo "Failed to connect to MySQL: " . $mysqli -> connect_error ;
  exit ( ) ;
}

$sql = "SELECT Lastname, Age FROM Persons ORDER BY Lastname" ;

if ( $result = $mysqli -> query ( $sql ) ) {
  while ( $obj = $result -> fetch_object ( ) ) {
    printf ( "%s (%s)\n" , $obj -> Lastname , $obj -> Age ) ;
  }
  $result -> free_result ( ) ;
}

$mysqli -> close ( ) ;
?>

例子2 - 過程式風格

返回結果集中的當前行，然後打印每個字段的值：

 <?php
$con = mysqli_connect ( "localhost" , "my_user" , "my_password" , "my_db" ) ;

if ( mysqli_connect_errno ( ) ) {
  echo "Failed to connect to MySQL: " . mysqli_connect_error ( ) ;
  exit ( ) ;  
}

$sql = "SELECT Lastname, Age FROM Persons ORDER BY Lastname" ;

if ( $result = mysqli_query ( $con , $sql ) ) {
  while ( $obj = mysqli_fetch_object ( $result ) ) {
    printf ( "%s (%s)\n" , $obj -> Lastname , $obj -> Age ) ;
  }
  mysqli_free_result ( $result ) ;
}

mysqli_close ( $con ) ;
?>
