起初想到制成XML文档形式,这样操作也起来很容易。只是看到说XML效率不怎样
再者就是不同的模板,可这样也有个小问题,有些词汇比如时间提示是不确定,与可能是minute ,day。也有可能复数加 s
那好吧,做成数组,可数组就得做成在php文件的变量,很难做些扩展(我所知道所认为的是这样)
最后做成txt文本文件的形式,同样也为这样的效率担心,打开文件,搜索字符串,截取字符串这些,所幸最后运行了一下,一般机子大概0.0004秒,这让我很惊奇原以为会很慢,毕竟要调用多次。
好吧,上代码
复制代码 代码如下:
class language
{
static $lanObject;
public $type; // unit , dashboard , menu ,other
public $lan; // language
private $special; // The common in the file
private function __construct()
{
if( isset($_GET['hl']) || isset($_POST['hl']) )
{
switch( isset($_GET['hl'])?$_GET['hl']:$_POST['hl'] )
{
case 'en':
$this->lan = 'en';
case 'zh':
$this->lan = 'zh';
case 'all':
$this->lan = 'all';
default:
$this->error();
}
}
else
$this->lan = isset($_COOKIE['hl']) ? $_COOKIE['hl']:'zh';
}
public static function getObject()
{
if( !(self::$lanObject instanceof self) )
self::$lanObject = new language();
return self::$lanObject;
}
public function lto($key) //$key is English
{
if( $this->lan !== 'zh' )
return $key;
if( empty($this->special) ) // if the $special is null
{
if( isset($this->type) )
$this->special = file_get_contents($this->type.'.txt');
else
return $key;
}
echo $this->search($key);
}
private function search($searchTozh) // PHP String
{
$key_start = strpos($this->special,$searchTozh);
$key_end = strpos($this->special,' ',$key_start);
$len_str = strlen($searchTozh);
$for_sub = $key_start + $len_str + 1;
return substr($this->special, $for_sub, $key_end - $for_sub);
}
}
strpos(); 是找到字符串第一次出现的位置 比如 ‘wo' 在 ‘hello world' 中,返回值为 6
substr();是截取字符串的一部分
接下来是调试时加上的代码
复制代码 代码如下:
$la = language::getObject();
$la->type = 'unit';
$la->lto('min');
echo '
';
$la->lto('hello');
lto(这里面要翻译的英文);
unit.txt 文件的内容格式是
hello-你好 min-小 minute-分钟 minutes-分钟
$special设计为全局也是想到不止一次会调用lto() ,如果反复加载文件太浪费性能了。
$type设计为公有是考虑到加载的文件的效率问题,有的时候并不需要显示几天前这些,所以不如把这些按使用类型分开,比如有专门负责菜单翻译的menu.txt ,也有专门为操作,比如删除,收藏 翻译的txt文本。这样可以自由设定要加载的文本
语言也可以自由设定。
好吧,程序还可以改进,我没有按http请求中的客户端语言来设置$lan,

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
