1.3. Chinese path problem, program file read encoding settings

PHP.ini in default_charset = "Utf-8" just set post,get encoding, Cannot set read code for PHP file: 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

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 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,systemsuch as function call System command

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

Different points :

　　exec You can return all the results of the execution to $output in the function ( array ), $status is the state of execution 0 for Success 1 to fail

　　systerm no need to provide $output function, he was directly returning the result, the same $return _var is the execution of the status code 0 for Success 1 to fail

　　exec Example :

1. The following is the reference content :

2. <?php

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. <?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, 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.
