将 Gettext 字符串分配给类成员
我正在制作一个将被翻译成 x 种语言的网站。
所有字符串都必须本地化。
有时我需要显示语言名称、国家/地区名称或从数据库检索的其他信息。以这种方式处理的数据很少会改变 - 如上所述,我谈论的是语言名称、国家/地区等。
在本例中,我使用的数组保存了网站 UI 已翻译成的语言。为了允许翻译名称(当“更改语言”标志/链接悬停时用于标题文本),我有一个像*这样的数组:
Array("zh_CN" => _("Chinese - Simplified"), "en_GB" => _("English"));
我使用它们来获取给定语言的相关名称字符串。
目前我正在使用全局数组:
$global_langNames = Array("zh_CN" => _("Chinese - Simplified"), "en_GB" => _("English"));
用法:
global $global_langNames;
echo $global_langNames[$code]; // $code = 'zh_CN'
输出(区域设置= en_GB):
简体中文
输出(区域设置 = zh_CN):
简体中文
我宁愿将这个(和其他)常量数组声明为类的私有成员,但 PHP 似乎不愿意:
class constants_lang{
private static $langNames = Array("zh_CN" => _("Chinese - Simplified"), "en_GB" => _("English"));
static function getLangName($code){
return self::$langNames($code);
}
}
结果:
Parse error: syntax error, unexpected '(', expecting ')' in /site/http/includes/classes/constants/lang.php on line 20
低下头并返回到全局数组,还是在那里另一种更好的方法让我以这种方式使用“常量”数组?
*数组键来自存储语言代码的数据库表以及我们是否有 UI 翻译:
code ui translation
zh_CN 1
en_GB 1
zh_TW 0
....
解决方案
class constants{
private $langNamesFromCode;
function __construct()
{
$this->langNamesFromCode = $this->initLangNamesFromCode();
}
/* INIT */
private static function initLangNamesFromCode()
{
return Array("zh_CN" => _("Chinese - Simplified"), "en_GB" => _("English"));
}
/* GETTERS */
public static function getLangNameFromCode($code)
{
if(self::isStatic()){
$langNamesFromCode = self::initLangNamesFromCode();
return $langNamesFromCode[$code];
}
else{
return $this->langNamesFromCode[$code];
}
}
/* UTILITY */
private static function isStatic()
{
return !(isset($this) && get_class($this) == __CLASS__);
}
}
I'm making a site that will be translated into x languages.
All strings must be localized.
There are occasions when I need to display a language name, country name or other information that has been retrieved from a database. The data being dealt with in this way will seldom be changed - as above I'm talking about language names, countries etc.
In this example I'm using the array that holds the languages into which the site's UI has been translated. To allow translation of the names (used for title text when the "change language" flag / link is hovered), I have an array like*:
Array("zh_CN" => _("Chinese - Simplified"), "en_GB" => _("English"));
I use them to get the relevant name string for a given language.
Currently I'm using a global array:
$global_langNames = Array("zh_CN" => _("Chinese - Simplified"), "en_GB" => _("English"));
Usage:
global $global_langNames;
echo $global_langNames[$code]; // $code = 'zh_CN'
Output (locale = en_GB):
Chinese Simplified
Output (locale = zh_CN):
简体中文
I would much rather declare this (and other) constant arrays as private members of the class, but it seems PHP isn't willing:
class constants_lang{
private static $langNames = Array("zh_CN" => _("Chinese - Simplified"), "en_GB" => _("English"));
static function getLangName($code){
return self::$langNames($code);
}
}
Results in:
Parse error: syntax error, unexpected '(', expecting ')' in /site/http/includes/classes/constants/lang.php on line 20
Should I hang my head low and go back to the global array, or is there another, better way for me to have a 'constant' array to be used in this manner?
*The array keys are from the database table storing language codes and whether we have a UI translation:
code ui translation
zh_CN 1
en_GB 1
zh_TW 0
....

class constants{
private $langNamesFromCode;
function __construct()
{
$this->langNamesFromCode = $this->initLangNamesFromCode();
}
/* INIT */
private static function initLangNamesFromCode()
{
return Array("zh_CN" => _("Chinese - Simplified"), "en_GB" => _("English"));
}
/* GETTERS */
public static function getLangNameFromCode($code)
{
if(self::isStatic()){
$langNamesFromCode = self::initLangNamesFromCode();
return $langNamesFromCode[$code];
}
else{
return $this->langNamesFromCode[$code];
}
}
/* UTILITY */
private static function isStatic()
{
return !(isset($this) && get_class($this) == __CLASS__);
}
}

是的,您只能在变量初始化中使用(大多数)文字。
解决方法是这样的:
Yes, you can only use (most) literals in variable initializations.
The work-around is something like:
您不能在成员声明中使用函数。如果您需要这样做,请将其移至构造函数或静态函数。
You cant use functions in member declarations. If you need to do this move it to the constructor or a static function.
