6 commonly used functions for executing Linux commands in PHP_PHP Tutorial

Under normal circumstances, php is rarely used to execute Linux commands, but under special circumstances, you may use these functions. I used to know that there are two functions that can execute linux commands, one is exec and the other is shell_exec. In fact, there are many. Based on the content of the manual, the following 6 functions are introduced.

1. exec function

<ol class="dp-xml"><li class="alt"><span><span class="tag"><?</span><span class="tag-name">php</span><span>     </span></span></li><li><span>$</span><span class="attribute">test</span><span> = </span><span class="attribute-value">"ls /tmp/test"</span><span>;   //ls是linux下的查目录，文件的命令     </span></li><li class="alt"><span>exec($test,$array);       //执行命令     </span></li><li><span>print_r($array);     </span></li><li class="alt"><span class="tag">?></span><span>   </span></span></li></ol>

The return result is as follows:

<ol class="dp-xml">
<li class="alt"><span><span>[root@krlcgcms01 shell]# php ./exec.php     </span></span></li>
<li><span>Array     </span></li>
<li class="alt"><span>(     </span></li>
<li>
<span> [0] =</span><span class="tag">></span><span> 1001.log     </span>
</li>
<li class="alt">
<span> [1] =</span><span class="tag">></span><span> 10.log     </span>
</li>
<li>
<span> [2] =</span><span class="tag">></span><span> 10.tar.gz     </span>
</li>
<li class="alt">
<span> [3] =</span><span class="tag">></span><span> aaa.tar.gz     </span>
</li>
<li>
<span> [4] =</span><span class="tag">></span><span> mytest     </span>
</li>
<li class="alt">
<span> [5] =</span><span class="tag">></span><span> test1101     </span>
</li>
<li>
<span> [6] =</span><span class="tag">></span><span> test1102     </span>
</li>
<li class="alt">
<span> [7] =</span><span class="tag">></span><span> weblog_2010_09     </span>
</li>
<li><span>)  </span></li>
</ol>
