当你正在处理很多参数提交的时候,你可能会碰到数据库查询,插入等等的操作,
这时你需要转义或者实体化
对安全不了解的phper初学者,写查询语句是这样写的
$sql="select * from demo where user='".$_POST['user']."'"";
那么就有sql注入的危险
一般有点经验的人写查询语句是这么写的
$sql="select * from demo where user='".addslashes($_POST['user'])."'"";
这样写没问题,就是
1、显得不专业
2、语句太多,每条都写,繁琐,难免遗漏
以我现在的掌握的知识再去写这条语句的话,我还是会写
$sql="select * from demo where user='".$_POST['user']."'"";
But我不是初学者,
我会在表单处理文件开头加上一句话,
$_POST=array_map("addslashes",$_POST);
实际源码示例
";var_dump($_POST);?>
打印出来的结果
array(2) { ["user"]=> string(4) "demo" ["content"]=> string(18) "Hello,It\'s a book"}
回复讨论(解决方案)
请叫我活雷锋
如果表单有同名控件,那么 $_POST=array_map("addslashes",$_POST); 就玩完了
是吧?活雷锋

表单同名控件指的是什么,可以举例说一下
最简答的就是复选框
答案1
答案2
答案3
虽然同名 text 控件可以设法回避掉
但复选框是绝对不能回避的
试了一下,果然,考虑不周,这个问题以后要注意一下了

活雷锋好。
所以要这样写
$a = array( 'a' => "a'b", 'b' => array("C'd", 123));array_walk_recursive($a, function(&$v) { $v = addslashes($v); });print_r($a);
Array( [a] => a\'b [b] => Array ( [0] => C\'d [1] => 123 ))
??方法太好了,之前???想到。
感??主分享。
果断收藏

就是写法报错了,提示错误
这位神仙 许久不见 我倒是挺想知道你那优雅的框架都有多少人下载 升级到什么版本了....另外javaScript 有什么高深作品给膜拜膜拜?

已经不执着于框架层面了,看到论坛上还有人在争论什么框架好、坏。
js插件可以去试试,弹窗的 http://tip.youyax.com/

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.

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.

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),

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.
