You could modify Your code to check for FALSE values that current() outputs when at the end of
array, like this:
<?php
$row = array( 'first'=>'number', 'second'=>'letter',
'third'=>null, 'forth'=>'word');
while(($value = current($row))!==FALSE){
echo "\"".key($row)."\"";
next($row);
}
?>
But then there would remaining the problem of what happens when there are FALSEs in the array.
The correct way is, like You said, the following:
<?php
foreach($row as $value){
echo "\"".key($row)."\"";
next($row);
}
?>
