php运行shell脚本

Question

I'm trying to run a shell script from a php frontend

heres the shell file (run.sh chmod to 777)

#!/bin/bash
wget -O index.html http://markets.usatoday.com/custom/usatoday-com/html-mktscreener.asp
python hw7-9.py index.html 
echo "done";

Heres the php front end

<?php
   $output = shell_exec("run.sh");
   echo "<pre>$output</pre>";
?>

But it php page doesn't return anything except

<pre></pre>

Answer 1

Have you tried doing error_reporting(-1); at the top of your PHP script. Likely shell_exec is disabled on your server.

Answer 2

你会尝试$ output = shell_exec（“sh run.sh”）;

Answer 3

检查php / web服务器实际运行的用户 - 例如“www-user”可能没有任何权限来执行脚本尝试执行的操作（并且有充分的理由）。
