從FTP或PHP

Question

運行bash文件（.SH）讓我承認，我從來沒有遇到來自PHP一個bash文件......，我無法做到這一點，雖然我試着用搜索引擎它使用shell_exec & system()

我收到了一個bgent腳本，它帶回了magento db，文件名是backu.sh。該文件位於magento根/var/www/html/backup.sh，我該如何運行此文件？

我試過到目前爲止

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

，但它並不顯示任何東西，也不是我能看到生成的文件...我的bash腳本看起來像

`#!/bin/sh

請幫助.. 。

嘗試：

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

通常，/path/to/sh是/bin/sh。

此外，你可以在你backup.sh腳本的末尾添加這一行：

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

這樣一來，如果你的腳本已成功執行，將創建一個名爲backupstatus.txt文件，其內容充滿了"backup.sh has been executed" 。
