让我承认，我从来没有从 php 运行过 bash 文件......尽管我尝试使用谷歌搜索并使用shell_exec& ，但我无法做到这一点system()

我有一个 bash 脚本，它收回了 magento db，文件名为backu.sh. 该文件位于 magento root /var/www/html/backup.sh，我该如何运行这个文件？

我试过到目前为止

$output=shell_exec('sh backup.sh >/dev/null &' ); echo "<pre>$output</pre>";

但它没有显示任何内容，我也看不到生成的文件......我的 bash 脚本看起来像

`#!/bin/sh

`

请帮忙...

谢谢..

尝试：

$output=shell_exec('/path/to/sh /var/www/html/backup.sh' ); 
echo "<pre>$output</pre>";

通常，/path/to/sh是/bin/sh。

此外，您可以在backup.sh脚本末尾添加这一行：

echo "backup.sh has been executed" >> /var/www/html/backupstatus.txt

这样，如果您的脚本已成功执行，backupstatus.txt将创建一个名为的文件，其内容将填充为"backup.sh has been executed".
