1. Execute the CMD command line and invoke the base of the system command

1.1. Actual execution mode

Processmonitor check. Get..

pid:115372, Command line:cmd.exe/c "D:\workspace to bake? \atibrow\exp_receipt.bat"

1.2. Questions about Spaces

Double Quote Resolution

1.3. Chinese path problem, program file read encoding settings

Default_charset = "Utf-8" in php.ini is just setting the encoding of Post,get and cannot set the read encoding of PHP files. It is best to comment out this parameter, let him according to the encoding of the file itself automatically judge, otherwise the output PHP results are header (' Content-type:text/html;charset=utf8

Author:: Old Wow's paw Attilax Ayron, email:1466519819@qq.com

The reason is that the PHP file itself is encoded using the system character set, Chinese Windows XP is GB2312, each file header has a field to indicate how the file is encoded

When compiling Java source files with Javac, the compiler reads the contents of the source file by default in the system code. If the source file is not saved with system encoding, you can specify the specific encoding with the command javac-encoding

Lymphatic, only not a PHP file encoding set to GBK. Just OK.

1.4. Echo garbled

Header (' CONTENT-TYPE:TEXT/HTML;CHARSET=GBK ');

2. Exec,system and other functions call system commands

These two are all used to invoke the system shell command,

Different points:

Exec can return all execution results to the $output function (array), $status is the execution status 0 for success 1 for failure

Systerm does not need to provide the $output function, he is directly returning the result, the same $return_var is the execution of the status code 0 for the success of 1 for the failure

exec Example:

1. The following is the reference content:

2.

3. $a = Exec ("dir", $out, $status);

4. Print_r ($a);

5. Print_r ($out);

6. Print_r ($status);

7.?>

System Example:

1. The following is the reference content:

2.

3. $a = System ("dir", $out);

4. Print_r ($a);

5. Print_r ($out);

6.?>

3. PHP.ini, turn off safe mode Safe_mode = Off

First, turn on php.ini, turn off safe mode Safe_mode = off, and then look at the list of disabled functions disable_functions = Proc_open, Popen, exec, System, shell_exec, remove exec.

4. Reference

PHP uses functions such as Exec,system to call system commands. htm
