If it is a php file, you can do this with 

 exec (nohup php /path/file.php);

nohup will put the proccess in the background, it will run even if you close a terminal or whatever.

To let it run every five seconds a simple 

for ($i = 0; $i < 1;)
{
   exec (nohup php /path/file.php);
   sleep(5);
}

should be enough.

Works with shell scripts and other files, too - just add nohup before your command.

Remember that nohup will create a logfile for every run, to suppress the output use nohup like this:

nohup command >/dev/null 2>&1
