问题
Is there any alternative for PHP exec(), shell_exec(), system(), passthrough() functions? As all these functions have security risk, need a way to execute server commands without using any of these functions.
Due to security reasons, can't enable these functions on my server php configuration. But as per website requirement, I need to execute some external commands like server ssh commands through php script. So, if there are any alternative ways to achieve same then please reply back to me.

You can write shell or bash scripts and invoke them through cron or set a daemon and let it check for a specific flag in database if you can do that.
