我猜当你说I do not want to use replacement function
你的意思是str_replace
每次打电话给助手时都会很费力。解决方案是用您自己的助手替换助手。这是一个快速的方法
首先创建一个您自己的助手,它扩展现有助手并在必要时处理替换...
<?php
namespace Application\View\Helper;
use Zend\I18n\View\Helper\CurrencyFormat;
class MyCurrencyFormat extends CurrencyFormat
{
public function __invoke(
$number,
$currencyCode = null,
$showDecimals = null,
$locale = null
) {
// call parent and get the string
$string = parent::__invoke($number, $currencyCode, $showDecimals, $locale);
// format to taste and return
if (FALSE !== strpos($string, 'TRY')) {
$string = str_replace('TRY', 'TL', $string);
}
return $string;
}
}
然后在 Module.php 中,实现 ViewHelperProviderInterface,并为它提供您的助手的详细信息
//Application/Module.php
class Module implements \Zend\ModuleManager\Feature\ViewHelperProviderInterface
{
public function getViewHelperConfig()
{
return array(
'invokables' => array(
// you can either alias it by a different name, and call that, eg $this->mycurrencyformat(...)
'mycurrencyformat' => 'Application\View\Helper\MyCurrencyFormat',
// or if you want to ALWAYS use your version of the helper, replace the above line with the one below,
//and all existing calls to $this->currencyformat(...) in your views will be using your version
// 'currencyformat' => 'Application\View\Helper\MyCurrencyFormat',
),
);
}
}
