RE: [PHP-DB] how to clear the array

2002-11-21 Thread Hutchins, Richard 
If you have a variable: $myArray = array();

Can't you clear it by saying unset($myArray)? According to the
documentation, it looks like you should be able to.

 How about:
 
 $my_array = array(); // clears the whole array (and makes a new one)
 
 Or:
 
 $my_array[$i] = null; // clears a single entry in the array 
 at index $i

RE: [PHP-DB] how to clear the array

Sorry. Didn't read original post.

Try this:

$myArray = array('1','2','3');
$numElements = count($myArray);
for($i=0;$i=$numElements;$i++){
unset($myArray[$i]);
}

If the code above doesn't work, check the link below. This all SOUNDS easy
enough to accomplish (theoretically), but I've never actually done it
before, so I'm not versed in the ins and outs of unsetting elements of an
array.
