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.
Examples
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); ?>
Notes
Note:
Always refer to the module-specific documentation as well.
The error message for Microsoft SQL Server is actually the result
of the mssql_get_last_message() function.
The error message for Oracle (oci8) is not implemented yet.
