PHP mysql_error() Function

Complete PHP MySQL Reference

Definition and Usage

The mysql_error() function returns the error description of the last MySQL operation.

This function returns an empty string ("") if no error occurs.

Syntax

mysql_error(connection)

Parameter	Description
connection	Optional. Specifies the MySQL connection. If not specified, the last connection opened by mysql_connect() or mysql_pconnect() is used.

Example

In this example we will try to log on to a MySQL server with the wrong username and password:

<?php
$con = mysql_connect("localhost","wrong_user","wrong_pwd");
if (!$con)
  {
  die(mysql_error());
  }
mysql_close($con);
?>

The output of the code above could be:

Access denied for user 'wrong_user'@'localhost'
(using password: YES)
