Executing Linux Commands With PHP on Linux Centos

Using Centos To Run Shell Commands With PHP Scripts

Linux has all sorts or neat packages you can install. Luckily, you may want to use one of them from a PHP script. This brief tutorial will explain how to do this.

The code below takes a submittted form and gathers the url into variable called $url. Then, the httrack service is used to clone the desired website.

 shell_exec('/usr/local/bin/httrack http://' . $url . '/  -O "/home/username/websites/     ' . $url . '"  -%v -%e0 2>&1;'); 

Besides PHP, you need to make modifications to the /etc/sudoers file on Linux. The change is shown below. 

 username ALL=NOPASSWD: /usr/local/lib/httrack,/usr/local/bin/httrack 

Now, when you open the folder /home/username/websites/ you will see the new clone.

Here is a simple may to open the new cloned folder with the Linux shell:

 cd *example.com
