dbx_error — Report the error message of the latest function call in the module

### 说明

dbx_error ( object `$link_identifier` ) : string

dbx_error() returns the last error message.

### 参数

`link_identifier`

  The DBX link object returned by dbx_connect()

### 返回值

Returns a string containing the error message from the last function call of the abstracted module (e.g. mysql module). If there are multiple connections in the same module, just the last error is given. If there are connections on different modules, the latest error is returned for the module specified by the `link_identifier` parameter.

### 范例

Example #1 dbx_error() example

    <?php
    $link   = dbx_connect(DBX_MYSQL, "localhost", "db", "username", "password")
        or die("Could not connect");

    $result = dbx_query($link, "select id from non_existing_table");
    if ($result == 0) {
        echo dbx_error($link);
    }
    dbx_close($link);
    ?>
