我目前有一个问题，我试图执行shell脚本解释文件和回声的HTML，shell脚本执行完美本地但是当我尝试通过PHP执行它不会返回任何东西，似乎是通过PHP根本没有执行它，我有一个文件，这是执行脚本时，不会显示与PHP执行时创build的。 我有其他脚本与PHP执行完全正常，我有适当的万维网数据权限来执行此文件。 请帮助我，这是我正在执行的脚本和执行它的PHP文件。

我在这里先向您的帮助表示感谢！
我认为问题是PHP在错误的位置寻找脚本。
您可以使用getcwd()获取当前的工作目录。 检查您是否正在使用从当前工作目录到脚本的正确相对路径。
否则，您可以简单地将脚本的绝对路径传递给exec()命令。
接下来的问题是你的shell脚本打印了很多行，并以</table></th> 。 exec()函数只返回shell脚本输出的最后一行。 所以PHP输出将只显示</table></th> 。 这不能在HTML中呈现，因为它们只是结束标记。 因此，您在浏览器中看不到任何更改，但是如果您检查HTML，则可以注意到它。
相反，您可以使用shell_exec()来返回shell脚本的整个输出。
这里是正确的版本：
<?php // 1.Remove the leading dot. The leading dot makes the path relative. // 2.Use shell_exec instead to get all lines from your script output. echo shell_exec('/var/www/html/newdongs/fetch_html.sh'); ?>
