# DB::isError()

DB::isError() -- Determines if a variable is a DB_Error object

## Synopsis

``boolean isError` (mixed $value)`

## Description

Checks whether a result code from a DB method is a DB_Error object or not.

You're generally better off using PEAR::isError() instead of the DB specific isError().

## Parameter

mixed `$value`

  Variable to check

## Return value

boolean - `TRUE` if `$value` is a DB_Error object

## Note

This function should be called statically.

## Example

Example 33-1. Using isError()
    <?php
    require_once 'DB.php';

    $db =& DB::connect('pgsql://usr:pw@localhost/dbnam');
    if (PEAR::isError($db)) {
        die($db->getMessage());
    }
    ?>
