Keep Looping Until True

[papaface]

Hey,

 

I am trying to create a loop based on a boolean output from a function.

This is essentially what I have:

function queue($skip)
{
  if ($skip == false)
   {
    //some code which will check their queue status and return true if they're in the queue or false if they're not.
   }
  else
   return true;
}

Then:

while (queue() == true)
{
//do something when they're in the queue
}

Is my code correct here?

Will it not check the queue() function only once?

 

Any help would be appreciated.

function queue($skip)
{
     if($skip == FALSE)
     {
          // check for new skip value
          $new_skip = // some value from database or something
          queue($new_skip);
     }
     return TRUE;
}

 

Note that you have the potential for an infinite loop if skip never returns true.

"Keep looping until true" would pretty much be a while loop with a negated conditional statement because a while "keeps looping until false".

To answer your question, no it will not check the queue function only once. It will check it each iteration.
