This is *not* typecasting at all, this is assignment of a result of
boolean operator, and it boils down to operator precedence.
It's equivalent to this code:
$b = $x == 11;
in the part that right side of equation sign is calculated first, then
assigned to lvalue. In effect, you wrote this:
$pos = (strpos($sText, "test") !== FALSE);
You would often use something like this in code:
$isSame = $x == $y;
which would put a boolean into $isSame, not put value of $x and then
compare it.
Bogdan,
you are reviving a thread over a week old, and repeating what 4 other
people have already stated. Please don't do that, it just results in
mailinglist-noise.

the computer determines such matters. Here is the full inventory.

<?php
foreach (glob("*.*") as $filename) {
echo '<img src="'.$filename.'">'."<br>\n$filename\n<P>\n";

This works nicely. copied code from online manual, chainsaw editing
to fit, superglue in the spare parts needed and it lists them all
and composes proper img links to display on the inventory page. NOW
I have the tool i needed; can someone else put this to good work?
