bash to php

grep $(echo "ab-c:de:f" | sed -e "s/[^0-9a-zA-Z]//g") filename.txt

I need this line to be converted to PHP only. the 'echo "ab-c:de:f" ' is going to be data filled in an input box from a form then php is going to take it and strip anything out that is not numberic or alphabetical and search the file from there. It would also be helpful if searches less than and greater than 6 characters (from the output of this command of course) were invalid searches.

Hi

Code:

echo "ab-c:de:f" | sed -e "s/[^0-9a-zA-Z]//g"
abcdef

The sed removes the "-" and ":" - did you intend it?

Anyway, to remove unwanted characters:

Code:

$safe = ereg_replace('[^0-9a-zA-Z]','',$unsafe);

To check if the length is 6:

Code:

if (strlen($safe) != 6)
  die("invalid search");

Thanks much! Yes, I intentionally removed the : and -'s, I did not want any other characters in the file except 0-9 and A-Z.

I will test the code when I have a chance.

Thanks again!
