搞前端的,请教一个简单php问题
$MySQLConnection = mysql_connect( "192.168.22.1", "root", "123456" );
@mysql_select_db( "first");
$Result = mysql_query("INSERT INTO `first`.`biao` (`hao`) VALUES ('$xingming');");
在我自己的页面写这个,是不是可以控制往192.168.22.1的first数据库里写东西, 这在php里面叫跨域吗? 192.168.22.1怎样防止这样的操作啊?
------解决方案--------------------
php 不存在跨域问题
mysql 默认只开放本地访问服务(127.0.0.1)
即便 192.168.22.1 就是本地ip地址,未经授权也不可访问
------解决方案--------------------
跨域是说AJAX跨域,这里没有跨域问题。

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
