cubrid_errno — Return the numerical value of the error message from previous CUBRID operation

### Description

The cubrid_errno() function is used to get the error code of the error that occurred during the API execution. Usually, it gets the error code when API returns false as its return value.

### Parameters

`conn_identifier`
  The CUBRID connection identifier. If the connection identifier is not specified, the last connection opened by cubrid_connect() is assumed.

### Return Values

Returns the error number from the last CUBRID function, or `0` (zero) if no error occurred.

### Examples

Example #1 cubrid_errno() example

`<?php
$con = cubrid_connect('localhost', 33000, 'demodb', 'dba', '');
$req = cubrid_execute($con, "select id, name from person");
if ($req) {
while (list ($id, $name) = cubrid_fetch($req))
echo $id, $name;
} else {
echo "Error Code: ", cubrid_errno($con);
echo "Error Message: ", cubrid_error($con);
}
?>`

The above example will output:

    Error Code: -493 Error Message: Syntax: Unknown class "person". select id, [name] from person
