Check to see if a function finishes

I am not sure how to word this, so please be patient.  I am probably thinking about this wrong.  How do I make sure that a function that I wrote finishes with no errors before moving on?  I am really looking to know if when I call a function and then have some processing to do after that function that it finished without problems.  Like I said I probably know how to do this, but I just cannot put my finger on it right now.

You would do something like:

<?php
function test () {
   <something that might fail>
  if (<it failed>)
   return 0;
 else
  return 1;
}

if (test())
   echo 'It worked';
else
  echo 'It failed';
?>

Hi, i agree with philetaylor, but if your function returns something other than '0' or '1' you could try something like this:

function test(){
     //Does something
     //Returns something
}

$testVar = test();
if(isSet($testVar))
{
      //it worked
}
else
{
      //it didn't work
}

hope it helps :)
