# Ant PHP Extension
2+
3+
PHP 扩展, 用于 PHP-FPM、FastCGI 模式下突破 `disabled_functions`。
4+
5+
### 原理
6+
7+
加载该扩展后, 可使用函数 `antsystem` 执行命令(相当于 `system` 别名)
8+
9+
eg:
10+
11+
```php
12+
<?php antsystem('whoami'); ?>
13+
```
14+
15+
### php.ini 样例
16+
17+
```
18+
disable_functions = pcntl_alarm,pcntl_fork,pcntl_waitpid,pcntl_wait,pcntl_wifexited,pcntl_wifstopped,pcntl_wifsignaled,pcntl_wifcontinued,pcntl_wexitstatus,pcntl_wtermsig,pcntl_wstopsig,pcntl_signal,pcntl_signal_get_handler,pcntl_signal_dispatch,pcntl_get_last_error,pcntl_strerror,pcntl_sigprocmask,pcntl_sigwaitinfo,pcntl_sigtimedwait,pcntl_exec,pcntl_getpriority,pcntl_setpriority,pcntl_async_signals,exec,shell_exec,popen,proc_open,passthru,symlink,link,syslog,imap_open,ld,mail,system
19+
```
20+
21+
### 编译
22+
23+
```bash
24+
$ cd ant_php_extension/
25+
$ phpize && ./configure && make
26+
```
27+
28+
编译完成后当前目录下的 `ant.so` 则是需要的文件
29+
30+
### 安装到本机
31+
32+
```bash
33+
$ cd ant_php_extension/
34+
$ phpize && ./configure && make
35+
$ make install
36+
37+
# 测试
38+
$ php -d enable_dl=On ant.php
39+
```
