Atitit.执行cmd 命令行 php

 

1. 执行cmd 命令行,调用系统命令的基础 1

1.1. 实际执行模式 1

1.2. 空格的问题 1

1.3. 中文路径的问题,程序文件读取编码设置 1

1.4. 回显乱码 2

2. exec,system等函数调用系统命令 2

3. php.ini,关掉安全模式safe_mode = off 3

1. 执行cmd 命令行,调用系统命令的基础

1.1. 实际执行模式

Processmonitor 检查。得到。。

PID: 115372, Command line: cmd.exe /c "D:\workspace 绌烘?\AtiBrow\exp_receipt.bat"

1.2. 空格的问题

双引号解决

1.3. 中文路径的问题,程序文件读取编码设置

Php.ini中的default_charset = "utf-8"  只是设置post,get的编码,不能设置php文件的读取编码。。最好是注释掉此参数,让他根据文件本身的编码自动判断,否则输出的php结果都 header('Content-Type:text/html;charset=utf8

 

作者:: 老哇的爪子 Attilax 艾龙,  EMAIL:1466519819@qq.com

 

 

原因在于php文件本身是用系统字符集来编码的,中文的windows XP都是用GB2312,每一个文件头部都有字段指示该文件是用何种方式编码的

 

用javac编译java源文件时,编译器默认用系统编码读源文件里的内容。如果源文件不是用系统编码来保存的,可以用命令javac -encoding指定具体的编码

 

淋巴,只能不个php文件的编码设置成gbk。。才ok。。

 

1.4. 回显乱码

 

 header('Content-Type:text/html;charset=gbk');  

 

 

2. exec,system等函数调用系统命令

 这二个都是用来调用系统shell命令,

  不同点:

  exec可以把执行的结果全部返回到$output函数里(数组),$status是执行的状态 0为成功 1为失败

  systerm不需要提供$output函数,他是直接把结果返回出来,同样$return_var是执行的状态码 0为成功 1为失败

  exec示例:

 

1. 以下为引用的内容:  

2. 

3. $a = exec("dir",$out,$status);  

4. print_r($a);  

5. print_r($out);  

6. print_r($status);  

7. ?> 

  system示例:

 

1. 以下为引用的内容:  

2. 

3. $a = system("dir",$out);  

4. print_r($a);  

5. print_r($out);  

6. ?> 

 

3. php.ini,关掉安全模式safe_mode = off

 

首先,打开php.ini,关掉安全模式safe_mode = off,然后在看看 禁用函数列表 disable_functions = proc_open, popen, exec, system, shell_exec ,把exec去掉。

 

 

4. 参考

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.

PHP Performance: Identifying and Fixing BottlenecksPHP Performance: Identifying and Fixing BottlenecksMay 11, 2025 am 12:13 AM

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

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

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.
