  • mysqli_stmt::$error_list()

    (PHP 5 >= 5.4.0, PHP 7)

    Returns a list of errors from the last statement executed

    说明

    面向对象风格
    array $mysqli_stmt->error_list;
    过程化风格
    mysqli_stmt_error_list(mysqli_stmt$stmt): array

    Returns an array of errors for the most recently invoked statement function that can succeed or fail.

    参数

    $stmt

    仅以过程化样式:由mysqli_stmt_init()返回的 statement 标识。

    返回值

    A list of errors, each as an associative array containing the errno, error, and sqlstate.

    范例

    Example #1 面向对象风格

    <?php
    /* Open a connection */
    $mysqli = new mysqli("localhost", "my_user", "my_password", "world");
    /* check connection */
    if (mysqli_connect_errno()) {
        printf("Connect failed: %s\n", mysqli_connect_error());
        exit();
    }
    $mysqli->query("CREATE TABLE myCountry LIKE Country");
    $mysqli->query("INSERT INTO myCountry SELECT * FROM Country");
    $query = "SELECT Name, Code FROM myCountry ORDER BY Name";
    if ($stmt = $mysqli->prepare($query)) {
        /* drop table */
        $mysqli->query("DROP TABLE myCountry");
        /* execute query */
        $stmt->execute();
        
        echo "Error:\n";
        print_r($stmt->error_list);
        /* close statement */
        $stmt->close();
    }
    /* close connection */
    $mysqli->close();
    ?>
    

    Example #2 过程化风格

    <?php
    /* Open a connection */
    $link = mysqli_connect("localhost", "my_user", "my_password", "world");
    /* check connection */
    if (mysqli_connect_errno()) {
        printf("Connect failed: %s\n", mysqli_connect_error());
        exit();
    }
    mysqli_query($link, "CREATE TABLE myCountry LIKE Country");
    mysqli_query($link, "INSERT INTO myCountry SELECT * FROM Country");
    $query = "SELECT Name, Code FROM myCountry ORDER BY Name";
    if ($stmt = mysqli_prepare($link, $query)) {
        /* drop table */
        mysqli_query($link, "DROP TABLE myCountry");
        /* execute query */
        mysqli_stmt_execute($stmt);
        
        echo "Error:\n";
        print_r(mysql_stmt_error_list($stmt));
        /* close statement */
        mysqli_stmt_close($stmt);
    }
    /* close connection */
    mysqli_close($link);
    ?>
    

    以上例程会输出:

    Array
    (
        [0] => Array
            (
                [errno] => 1146
                [sqlstate] => 42S02
                [error] => Table 'world.myCountry' doesn't exist
            )
    )
