PHP执行linux命令常用函数汇总,phplinux命令汇总

一般情况下,很少会用php去执行linux命令,不过特殊情况下,你也许会用到这些函数。以前我知道有二个函数可以执行linux命令,一个是exec,一个是shell_exec。其实有很多的,结合手册内容,介绍以下6个函数。

1,exec函数

<&#63;php 
$test = "ls /tmp/test"; //ls是linux下的查目录,文件的命令
exec($test,$array); //执行命令
print_r($array);
&#63;>

返回结果如下:

[root@krlcgcms01 shell]# php ./exec.php 
Array 
( 
[0] => 1001.log 
[1] => 10.log 
[2] => 10.tar.gz 
[3] => aaa.tar.gz 
[4] => mytest 
[5] => test1101 
[6] => test1102 
[7] => weblog_2010_09 
)

2,system函数

<&#63;php 
$test = "ls /tmp/test";
$last = system($test);
print "last: $last\n";
&#63;>

返回结果:

[root@krlcgcms01 shell]# php system.php 
1001.log 
10.log 
10.tar.gz 
aaa.tar.gz 
mytest 
test1101 
test1102 
weblog_2010_09 
last:weblog_2010_09

3,passthru函数

<&#63;php 
$test = "ls /tmp/test";
passthru($test);
&#63;>

4,popen函数

<&#63;php 
$test = "ls /tmp/test";
$fp = popen($test,"r"); //popen打一个进程通道

while (!feof($fp)) { //从通道里面取得东西
$out = fgets($fp, 4096);
echo $out; //打印出来
} 
pclose($fp);
&#63;>

5,proc_open函数

<&#63;php 
$test = "ls /tmp/test";
$array = array(
array("pipe","r"), //标准输入 
array("pipe","w"), //标准输出内容 
array("pipe","w") //标准输出错误 
); 
$fp = proc_open($test,$array,$pipes); //打开一个进程通道
echo stream_get_contents($pipes[1]); //为什么是$pipes[1],因为1是输出内容
proc_close($fp);
&#63;>

6,shell_exec函数

<&#63;php 
$test = "ls /tmp/test";
$out = shell_exec($test);
echo $out;
&#63;>

popen,passthru,proc_open,shell_exec的返回结果如下:

[root@krlcgcms01 shell]# php test.php 
1001.log 
10.log 
10.tar.gz 
aaa.tar.gz 
mytest 
test1101 
test1102 
weblog_2010_09

我能发现的就这几个函数,能执行linux下的命令,我想应当还有吧,欢迎大家补充。
