Nistan, Just got home, tested on linux. No problem on linux, the control-z just exits. I may just go ahead and post my issue to the PHP windows list to see if anything comes up, and not worry if it doesnt. I appreciate the help very much Thanks, Jesse -----Original Message----- From: Jesse.Hazen@xxxxxxxxxxxxx [mailto:Jesse.Hazen@xxxxxxxxxxxxx] Sent: Thu 3/26/2009 2:17 PM To: nitsanbn@xxxxxxxxx Cc: php-general@xxxxxxxxxxxxx Subject: RE: 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.

The second option looped an error: Warning: preg_replace(): Compilation failed: nothing to repeat at offset 17 Thanks, Jesse Hazen ________________________________ From: nitsan@xxxxxxxxxxxx [mailto:nitsan@xxxxxxxxxxxx] On Behalf Of Nitsan Bin-Nun Sent: Thursday, March 26, 2009 1:58 PM To: Hazen, Jesse, arvato digital services llc Cc: php-general@xxxxxxxxxxxxx Subject: Re: Regex I have no idea about this control-Z thing, you might want to try it with UTF (just add the 'u' modificator): $str = preg_replace("#[^a-zA-Z0-9]+#uis", "", $str); Or try this: $str = preg_replace("#(\b[^a-zA-Z0-9]\b?)+#uis", "", $str); I may be wrong about the second one but it might work...

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.

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? 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? Thanks, Jesse Hazen
