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
