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) {
This is *never* going to be true, mainly because $char cannot be equal
to both 0xA7 *and* 0x51 at the same time.
return $x;
}
}
but it never matches. Any pointers?
Yeah, understand the code before attempting to port it. The if you
posted at the top is trying to find 0xA7 followed by 0x51. Your ported
code is not.
Try this...
$buffer = file_get_contents('Dining_Room.rti');
$count = strlen($buffer);
for ($x=0; $x < $count; $x++) {
$char1 = substr($buffer, $x, 1);
$char2 = substr($buffer, $x+1, 1);
echo $char1;
if ($char1 == 0xa7 && $char2 == 0x51) {
return $x;
}
}
