Using shell with Zend Framework - php

Question

I'm curios if Zend has a component which can make use of the shell. For example I want to do an shell command like this:
mysqldump --compact --uroot --ppass mydatabase mydable >test.sql
from a controller.
If there isn't, do you know a way how to dump data from tables in Zend Framework?
update:
I've found a way here http://www.zfsnippets.com/snippets/view/id/68

There's no direct exec() support in the zend framework. the closest to command line support there is the Zend_Console class, but it's meant for getting arguments from the command line.
I would wrap the exec() function as a process object and work with that. Here's a nice example from the php docs:
<?php
// You may use status(), start(), and stop(). notice that start() method gets called automatically one time.
$process = new Process('ls -al');
// or if you got the pid, however here only the status() metod will work.
$process = new Process();
$process.setPid(my_pid);
?>
<?php
// Then you can start/stop/ check status of the job.
$process.stop();
$process.start();
if ($process.status()){
echo "The process is currently running";
}else{
echo "The process is not running.";
}
?>
<?php
/* An easy way to keep in track of external processes.
* Ever wanted to execute a process in php, but you still wanted to have somewhat controll of the process ? Well.. This is a way of doing it.

class Process{
private $pid;
private $command;
public function __construct($cl=false){
if ($cl != false){
$this->command = $cl;
$this->runCom();
}
}
private function runCom(){
$command = 'nohup '.$this->command.' > /dev/null 2>&1 & echo $!';
exec($command ,$op);
$this->pid = (int)$op[0];
}
public function setPid($pid){
$this->pid = $pid;
}
public function getPid(){
return $this->pid;
}
public function status(){
$command = 'ps -p '.$this->pid;
exec($command,$op);
if (!isset($op[1]))return false;
else return true;
}
public function start(){
if ($this->command != '')$this->runCom();
else return true;
}
public function stop(){
$command = 'kill '.$this->pid;
exec($command);
if ($this->status() == false)return true;
else return false;
}
}
?>
It's also let you stop and check the status of a job.
