解决Laravel中的mb_strimwidth()引起的问题。

• 问题：安装php artisan breeze:install时出现以下错误。
  Call to undefined function Termwind\ValueObjects\mb_strimwidth()
  问题就是：mb_strimwidth()不能识别，那么就解决宽字符问题，就能解决。

 php artisan breeze:install           

  Which Breeze stack would you like to install?

   Error

• 查看一下版本：

php --version
PHP 8.3.1 (cli) (built: Dec 20 2023 14:06:10) (ZTS Visual C++ 2019 x64)
Copyright (c) The PHP Group
Zend Engine v4.3.1, Copyright (c) Zend Technologies

• 因此解决：对应版本的php.ini中，添加：extension=php_mbstring.dll。支持宽字符串，问题就应该得到解决。参考配置如下：

[Date]
date.timezone=Asia/Shanghai
[PHP]
max_execution_time = 300
max_input_time=60
max_input_vars=3000
memory_limit=256M
upload_max_filesize = 100M
post_max_size = 100M
max_file_uploads = 100
display_errors = On
display_startup_errors=On
log_errors=On
track_errors=Off
html_errors=On
error_log=C:/phpstudy_pro/Extensions/php/php-8.3.1-Win32-vs16-x64.log
error_reporting=E_ALL & ~E_NOTICE
allow_url_fopen=On
allow_url_include=Off
extension_dir="C:\phpstudy_pro\Extensions\php\php-8.3.1-Win32-vs16-x64\ext"
extension=php_pdo_mysql
extension=php_openssl.dll
extension=php_mbstring.dll
extension=zip
extension=curl
variables_order = "GPCS"
extension=php_fileinfo

• 经过测试，加入extension=php_mbstring.dll后，再次执行结果如下：

 php artisan breeze:install

  Which Breeze stack would you like to install?
  Blade with Alpine ...................................................................................................... blade  
  Livewire (Volt Class API) with Alpine ............................................................................... livewire  
  Livewire (Volt Functional API) with Alpine ............................................................... livewire-functional  
  React with Inertia ..................................................................................................... react  
  Vue with Inertia ......................................................................................................... vue  
  API only ................................................................................................................. api  
❯ 

至此，问题成功解决。
