<?
$first_name = "Hello";
$second_name = "Hello";

if(strcasecmp($first_name,$second_name)) {
 echo "words are equal";
}
else
{
 echo "words are not equal.";
}
?>
..............

In strcasecmp() - this comparison will return 0 - interpreted by PHP as
FALSE - eventhough words are _equal_ so what will execute is "words are not
equal".
whereas if the negation symbol of ! is inserted as in:

.......
<?
$first_name = "Hello";
$second_name = "Hello";

if(!strcasecmp($first_name,$second_name)) {
 echo "words are equal";
}
else
{
 echo "words are not equal.";
}
?>
...........

to read if the comparsion which is returned is not _FALSE_ excecute:
"words are equal."
.............

Am I on the right track with this logic?
Thank you.
