我正在使用名为spop的spotify插件:https://github.com/Schnouki/spop
现在我想创建一个传递命令并返回字符串的搜索系统,然后我可以解析它并使其可读等。
如果我这样做,它可以工作,返回我想要的东西:
echo shell_exec('echo hello'); //returns hello
现在我想做(不返回任何内容):
echo shell_exec('echo search "new release 2017" >/dev/tcp/localhost/6602'); //Returns nothing
有什么想法吗?现在我尝试了<pre>$output</pre>
。描述:http://php.net/manual/en/function.shell-exec.php#example-4218
我只想返回搜索命令的输出。我应该收到像这样的东西:
