HomeBackend DevelopmentPHP Tutorialjavascript - post和显示特殊字符的处理

<code><input type="text" value="测试'-">数据" />
</code>

显示结果如下图:
"javascript

好,问题来了,当我在input框中输入一般字符,保存到数据库和最终取回在input中取出显示没有问题。

当输入例入' " 这种特殊字符的时候,虽然在php获取和取出的过程中都加了\和去了\,但是最终这些字符都还是要在input中显示的,那就会造成html格式的错乱。

我现在的做法,用中文的‘和"替换英文的'和",然后还在post接收的时候替换成转义符,比如:

<code><        <   小于号或显示标记
>        >   大于号或显示标记
&   &   可用于显示其它特殊字符
"  "   引号
</code>

但始终不是最好的办法,请问:

1.好的处理方法怎么做?

2.在诸如kingeditor和fck这样的编辑器中又是怎么处理的?

输出时转义即可
htmlspecialchars()

很明显,你就不应该这样转义。

你应该要把双引号转成 " 这类字符的嘛。

自己来结贴:
1.sql写入前用addslashes()对特殊字符加斜杠
2.sql取出后用tripslashes()对特殊字符去斜杠
3.输出html时使用htmspecialchars()把特殊字符转成html转义符

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

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.

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

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.

SecLists

SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
