Cakephp中如何实现i18n?
好像网上一直没有比较详细的中文资料来讲述如何使用cakephp来实现i18n。正好昨天被逼无奈的将代码中的提示中文化了一把,略有心得,简而志之。
中文化cakephp有如下几步:
1,在代码中使用__()函数。
在需要进行中文化的地方使用__()函数,如下所示:
__('This is the string i need to translate', true);
将第2个参数置为ture,这样如果有相对应的翻译词条的话那么翻译过的词条将输出,否则会输出未翻译的词条。
2,执行i18n task
如果你的代码中存在__()函数的话,你就可以执行i18n task来进行代码扫描了。
i18n task的作用是扫描源码中所有__()函数,为__()中的string建立翻译索引并将这些索引保存在.pot文件中。
那么如何执行i18n task呢?
命令行进入你项目的app目录
如果是windows平台,请确保环境变量的PATH中包含php的bin路径,并确保你cake目录下的cake\console也存在于环境变量的PATH中
执行命令 cake i18n,这时候应该会出现如下所示的提示,选择E既可
---------------------------------------I18n Shell---------------------------------------[E]xtract POT file from sources[I]nitialize i18n database table[H]elp[Q]uitWhat would you like to do? (E/I/H/Q)>
i18n task执行完毕后应该\app\locale目录下生成名为default.pot的文件,将这个文件拷贝至\app\locale\chs\LC_MESSAGES目录下
使用pot文件的编辑工具翻译词条。推荐使用Poedit
在\app\config\core.php中加上如下代码:
Configure::write('Config.language', 'chs');
好了,这样就完成简单的项目中文化了。
其中很多细节由于篇幅原因就不做完整介绍了。有疑问的话请参考cakephp的帮助文档。

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.

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.
