IntlCalendar::getErrorCode -- intlcal_get_error_code — Get last error code on the object

### 説明

オブジェクト指向型 (method):

public IntlCalendar::getErrorCode ( void ) : int

手続き型:

intlcal_get_error_code ( IntlCalendar `$calendar` ) : int

Returns the numeric ICU error code for the last call on this object (including cloning) or the IntlCalendar given for the `calendar` parameter (in the procedural‒style version). This may indicate only a warning (negative error code) or no error at all (`U_ZERO_ERROR`). The actual presence of an error can be tested with intl_is_failure().

Invalid arguments detected on the PHP side (before invoking functions of the ICU library) are not recorded for the purposes of this function.

The last error that occurred in any call to a function of the intl extension, including early argument errors, can be obtained with intl_get_error_code(). This function resets the global error code, but not the objectʼs error code.

### パラメータ

`calendar`

  The calendar object, on the procedural style interface.

### 返り値

An ICU error code indicating either success, failure or a warning.

### 例

例1 IntlCalendar::getErrorCode() and IntlCalendar::getErrorMessage()

`<?php
ini_set("intl.error_level", E_WARNING);
ini_set("intl.default_locale", "nl");
$intlcal = new IntlGregorianCalendar(2012, 1, 29);
var_dump(
$intlcal->getErrorCode(),
$intlcal->getErrorMessage()
);
$intlcal->fieldDifference(-1e100, IntlCalendar::FIELD_SECOND);
var_dump(
$intlcal->getErrorCode(),
$intlcal->getErrorMessage()
);`

上の例の出力は以下となります。

    int(0)
    string(12) "U_ZERO_ERROR"

    Warning: IntlCalendar::fieldDifference(): intlcal_field_difference: Call to ICU method has failed in /home/glopes/php/ws/example.php on line 10
    int(1)
    string(81) "intlcal_field_difference: Call to ICU method has failed: U_ILLEGAL_ARGUMENT_ERROR"
