显示树莓派状态信息的PHP页面

将下面的代码复制下来保存为php页面，访问这个页面就能查看实时的树莓派状态信息了。原理是打印shell_exec的结果。

<?php

    /**

    * state

    *

    * @package custom

    */

?>

	<article class="content">

	<section class="post">

		<div id='server_state'>

			<h5>uname -a</h5>

			<pre><?php echo shell_exec("uname -a"); ?></pre><br/>

    

			<h5>Uptime</h5>

			<pre><?php echo ltrim(shell_exec("uptime"), " "); ?></pre><br/>

    

			<h5>cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq </h5>

			<pre>

				<?php

					$t = shell_exec("cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq");

        	echo sprintf("%s/1000=%sKHz", str_replace("\n", "", $t), $t/1000);

				?>

			</pre><br/>

    

			<h5>cat /sys/class/thermal/thermal_zone0/temp </h5>

			<pre>

				<?php

					$t = shell_exec("cat /sys/class/thermal/thermal_zone0/temp");

        echo sprintf("%s/1000=%sC°", str_replace("\n", "", $t), $t/1000);

       ?>

      </pre><br/>

    

			<h5>free -h</h5>

			<pre><?php echo shell_exec("free -h"); ?></pre><br/>

    

			<h5>cat /proc/cpuinfo</h5>

			<pre><?php echo shell_exec("cat /proc/cpuinfo"); ?></pre>
