Hallo,
I am adding a value to a session variable (an array). Then I want to place
the key of the array in another session variable to keep it for later use
(so I can return to the array to write data to it). The key function should
work there, but it seems to be a bit strange.
Imagine:
$array = array();
$array[] = "Yellow";
$array[] = "Geen";
$array[] = "Red";
foreach ($array as $key=>$value)
{
print ("Key: " . $key . " has color " . $value . " | ");
print ("current key = " . key($array) . "<br/>");
}
If you run the loop the key value returned from key is one higher than the
key in $key, and the last key is null?
How do I get the present key without a problem??
Thanks!!
