I've been trying to figure out a way to do this all day and I'm afraid
I might need a bit of help. Basically I am trying to port over
something from Java to PHP and I'm stuck on one particular piece of
code:
if ((ba[i + 0] == (byte)0xa7) && (ba[i + 1] == (byte)0x51)) {
The code is looping through a byte array and checking if the current
value matches "(byte)0xa7", etc. If there is a match, then it breaks
and returns the value of i. There are quite a few more values than
this in the conditional, but I figure this is enough to get the point
across. My problem is I'm not exactly sure what the value of
(byte)0xa7 is.
I tried
$buffer = file_get_contents('Dining_Room.rti');
$count = strlen($buffer);
for ($x=0; $x < $count; $x++) {
$char = substr($buffer, $x, 1);
echo $char;
if ($char == 0xa7 && $char == 0x51) {
return $x;
}
}
but it never matches. Any pointers?
