Belgarion is right, this is not valid syntax. But what you really want to do is fork and execute the command in a sub-process. Like this: 

$pid = fork;

if ($pid) {
  #This is the parent, continue processing 
} 
else {
  #this is the child, so exec
  #which will replace the child
   exec("echo HELLO WORLD");
}
