RE: [PHP] Regex
Jochem,
Thanks, but this regex did not seem to work for me. At least, not on
Windows. I will not be able to test on linux for a few hours.
I spoke too soon yesterday, too. Control-Z is a problem on Windows, and
not on Linux. However, on linux, control-D is a problem.
Thanks,
Jesse Hazen

Hi,
Brand new to regex. So I have a cli which runs a regex on users input,
to make sure that only 0-9 and A-Z are accepted. It should strip
everything else. My problem is that when you press control-Z (on
Windows; I have not yet tested this on linux, and I will, but I would
like this to be compatible with both OS's) it loops infinitely saying
invalid data (because of the next method call, which decides what to
do
based on your input). So, here is the input code. Is there a way I can
ensure that control commands are stripped, here?
there is, your control-Z is not a Z at all, and it's only printed as ^Z
so you can see it ... it's actually a non-printing char.
try this regexp for stripping control chars:
/[\x00-\x1f]+/
public function getSelection() {
$choice =
$this-validateChoice(trim(strtoupper(fgets(STDIN;
return $choice;
}
private function validateChoice($choice) {
$choice =
ereg_replace(/[^0-9A-Z]/,,$choice);
return $choice;
}
I have tried a ton of different things to try and fix this. Tried
/\c.|[^0-9A-Z]/, and many variations of \c and the [^0-9A-Z], to no
avail. I also tried using both preg_replace() as well as
ereg_replace().
I spent a lot of time on the regex section of the PHP manual, but I am
not finding anything. Any advise on how to accomplish this?

RE: [PHP] Regex
Bruce,
Sure thing. So basically what I am trying to accomplish is when this
script runs, a menu is displayed to the user, it looks somewhat like
this:
Welcome
To continue, please select your game mode.
[Mode] [Description]
A.) Mode A
B.) Mode B
C.) Mode C
D.) Mode D
E.) Mode E
F.) Mode F
Q.) Quit.
To begin, please type the mode letter.
Mode:
Then, the below lines of code come into play:
public function getSelection() {
$choice =
$this-validateChoice(trim(strtoupper(fgets(STDIN;
return $choice;
}
private function validateChoice($choice) {
$choice = preg_replace(/[\x00-\x1f]+/,,$choice);
return $choice;
}
So now the script is waiting for user input. The next thing to happen,
right after this code, is:
private function validate($choice,$display,$input) {
$valid = false;
while(!$valid) {
switch($choice) {
case Q:
$display-writeCredits();
sleep(4);
exit(0);
case A:
$valid = true;
break;
case B:
$valid = true;
break;
case C:
$valid = true;
break;
case D:
$valid = true;
break;
case E:
$valid = true;
break;
case F:
$valid = true;
break;
default:
$display-writeInvalidChoice();
$choice =
$input-getSelection();
break;
}
}
return $choice;
}
Now, this is where the script loops infinitely. But, this is only the
first method which validates user input. There are several others.
Basically, my script should accept user input, strip anything that will
not be needed (like anything other than letters and numbers) and then
allow the user to proceed, where the script checks to see if the
numbers/letters they entered correspond to the menu's in any way.
Everything in the script runs perfect, except the fact that the control
statements print infinitely. And while I am sure there is something I
could do to this method to make it not loop infinitely, I would also
need to do this to several other loops.
Thanks,
Jesse Hazen

RE: [PHP] Regex
Nitsan,
Thank you very much for the input. However, I just gave this a try and
it still did not strip the control-Z. Therefore, it is still hitting my
loop later and looping infinitely. I am sure I could mend that by
working something into that loop, but there are several loops I would
need to do this on. If I can stop the command at this method, then the
entire script will run perfectly.
Thanks,

RE: [PHP] Regex
Nitsan,
Not a problem, thanks for the help. So, it is printed as ^Z. However, I
created a little test.php script to accept input and print it back to
me. So, I used control z as my test, and it simply printed a line, and
that's all. So, then I input control z, and then had it print a letter
right after (a), and it was just the letter a. no whitespace, no
breaks, nothing.
I even tried one more thing: in the loop (not in the code below) I put
unset($choice), right above where it tells the user their input is
invalid and asks for it again. Even this did not change anything: when
pressing control - z, it looped infinitely.
I assumed that \c would be the regex to mend this, as the php manual has
this as control-x, where x is any character. I even tried every
variation of this, with a key combination like \cZ, or \cz, or \c[zZ],
yet it still does not catch it.

[PHP] PHP-CLI issue
Hi,
I am working on building a PHP-CLI 'game' for converting
binary/hex/decimal, to better your speed at converting between base
number systems. I started on the game class, and created a little menu
with user input for different game modes. If the user inputs invalid
data, the script is supposed to say 'invalid' and ask for the input
again. Then, as long as the data remains invalid, the user is
continuously prompted until the data is valid, whereas the correct
method is called.
My issue is that when invalid data is input, the 'invalid, try again'
message is displayed 3 times before the script stops for the user to try
again. So instead of:
Invalid data. Mode: (here, waits for the user to input)
it says:
Invalid data. Mode:

I have tried altering my loop a few different ways, to no avail. This is
also my very first php-cli and so I am a bit of a newb when it comes to
php-cli. The code is below. I'm not worried about other portions of the
code at this point; can anyone see what I am doing incorrectly that is
looping this message three times instead of just displaying once?
class BaseGame {
public function run() {
fwrite(STDOUT,$this-welcome());
$input = $this-getSelection();
$this-decideMode($input);
}
private function welcome() {
$menu = Welcome to the Binary/Hexadecimal
conversion Practice Tool.\n;
$menu.= This tool is used as a game for
learning binary/hexadecimal/decimal conversion.\n\n;
$menu.= \tTo continue, please select your game
mode.\n\n;
$menu.= \t[Mode]\t[Description]\n;
$menu.= \tA.)\tGiven a random binary value,
resolve to decimal.\n;
$menu.= \tB.)\tGiven a random binary value,
resolve to hexadecimal.\n;
$menu.= \tC.)\tGiven a random hexadecimal
value, resolve to binary.\n;
$menu.= \tD.)\tGiven a random hexadecimal
value, resolve to decimal.\n;
$menu.= \tE.)\tGiven a random decimal value,
resolve to binary.\n;
$menu.= \tF.)\tGiven a random decimal value,
resolve to hexadecimal.\n;
$menu.= \tG.)\tGiven two random values, decide
which is larger.\n;
$menu.= \tQ.)\tQuit.\n\n;
$menu.= \tTo begin, simply type the mode
letter.\n\n;
return $menu;
}
private function getSelection() {
fwrite(STDOUT,Mode: );
$input = strtoupper(fgetc(STDIN));
return $input;
}
private function decideMode($input) {
while($input) {
if($input == Q) { exit(0); }
elseif($input == A) {
$this-binary2decimal(); }
elseif($input == B) {
$this-binary2hexadecimal(); }
elseif($input == C) {
$this-hexadecimal2binary(); }
elseif($input == D) {
$this-hexadecimal2decimal(); }
elseif($input == E) {
$this-decimal2binary(); }
elseif($input == F) {
$this-decimal2hexadecimal(); }
elseif($input == G) {
$this-comparison(); }
else {
fwrite(STDOUT,\nInvalid
choice. Choose again.\n);
$input =
$this-getSelection();
}
}
exit(0);
}
RE: [PHP] PHP-CLI issue
Rob,
Thanks for the quick reply. I did try that before, but now my issue is
that the if-else section does not recognize the data as being valid. So,
I changed it to fgets(), and reran, this time using valid data. The
initial problem is corrected (it only gives the error once), but now it
does not recognize my data, and I get the error once no matter what I
input. Is there anything in particular I would need to do to the
variable, after the STDIN, to prepare it for the validation?
Thanks,
Jesse Hazen

Use fgets() instead of fgetc(). You're retrieving one character at a
time. When someone hits enter... 1 (or in winblows 2) extra characters
are usually put on the input stack that represent the enter key itself.
Cheers,
Rob.

Use trim() to trim the retrieved input since it will have the newline appended to it. Then you can do your comparison.
