Can I test the element of a array in a if using the current() function after stuff a

[whitejeep]

I am trying to parse the strings returned from the construct_forum_chooser function and use the -- as a dlimater value to break out each substring I do cast the result to a array before stuffing it into the array each time. I have put the code in a while loop that will loop forever but i need a way the know that i am at the end of the string by stuffing a empty string in to the array so i want to find a way to test that the value in the array is empy and i tried to use the current() and test to see if the element is empty. DOES ANY ONE HAVE A IDEA HOW TO DO THAT - can i test the array at the same time as i am putting a value in it by using current() in a if statement

$grouplist = construct_forum_chooser(); Note: now I know it returns a string because i tested with var_dump function.

echo var_dump($grouplist); // Note: Returns a string

$grouplistarray = array();

// $grouplistarray = (array) strtok($grouplist,'--'); // Intersting obervasison the array then first element with
// dot or just first element with out dot - Note if i add the cast operator and cast the results returned from the
// strtok function I have to then remove the dot before the = which means contatation of a string but will not work
// on a array. So now to fill the array we need to put it in a loop.

$grouplistarray = (array) strtok($grouplist,'--');

I put the above line in a while loop see below this is to load the string in to the array $grouplistarray :

while ($FOREVER) {

$grouplistarray = (array) strtok($grouplist,'--');

// NOW I NEED TO CREATE A IF TEST TO TEST TO SEE IF I AM AT THE END OF THE STRING BY TESTING THE VALUE SEE IF IT EMPTY() BEFORE PUTTING THE STRING AFTER IT IS CAST TO A ARRAY IN TO THE ARRAY SO I CAN BREAK OUT OF THE WHILE.

if (????????) { // FALSE by using the ! expresion
break;
}

}

THE IF TEST I WANT TO USE A POINTER TO THE ELEMENT JUST STUFFED TO THE ARRAY?
