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

Return value

boolean - TRUE if $value is a DB_Error object

Note

This function should be called statically.

Example

Using isError()

<?php
require_once 'DB.php';

if (PEAR::isError($db)) {
    die($db->getMessage());
}
?>
