Two-pin solution

1.3. Chinese path problem, program file read encoding settings

The default_charset = "Utf-8" in php.ini is simply the code that sets the post,get , Cannot set read encoding for PHP file:

It is better to stare at this number, let him according to the encoding of the file itself to infer, otherwise the output PHP results are header (' Content-type:text/html;charset=utf8

The reason is PHP The file itself is encoded using the system character set, the Chinese Windows XP It's all used GB2312 . Each file header has a field that indicates how the file is encoded.

When compiling a Java source file with Javac, the compiler reads the contents of the source file by default with the system encoding.

Assuming that the source file is not saved with system encoding, you can specify a detailed encoding with the command javac-encoding

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

Just OK.

1.4. Echo garbled

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

2. Exec,systemsuch as function call System command

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

Different points :

　　exec The ability to return all running results to the $output in the function ( array ), $status is the state of the run 0 for Success 1 to fail

　　systerm no need to provide $output function, he is directly returning the result. Same $return _var is running status code 0 for success 1 for failure

　　exec Demo Sample :

1. The following is the referenced content :

2. <?

Php

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

4. Print_r ($a);

5. Print_r ($out);

6. Print_r ($status);

7.?>

　　system Demo Sample :

1. The following is the referenced content :

2. <?

Php

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, open the php.ini. Turn off Safe Mode Safe_mode = off, then look at the list of disabled functions disable_functions = Proc_open, Popen, exec, System, shell_exec, remove exec.
