Returns a string description of the last connect error (PHP 5)
string mysqli_connect_error ( )

The mysqli_connect_error() function is identical to the corresponding mysqli_connect_errno() function in every way, except instead of returning an integer error code the mysqli_connect_error() function will return a string representation of the last error to occur for the last mysqli_connect() call. If no error has occured, this function will return an empty string.


A string that describes the error. An empty string if no error occurred.
