Piping Data to a Script

[Anon]

Say I want to analyze files and strip out their HTML as I view it. I could cat <file> but there's no strip-html feature in Linux. I could write a script that uses PHP's strip_tags feature, but I'd prefer it if I could code it in such a way that it can read live input, like if I were watching live traffic and not a static file. How can I pipe data to a PHP script and have it read the data line-by-line as it comes in? I want to be able to do this:

cat <file> | stripper.php

(where stripper's header is #!/usr/bin/php -q of course)

Ideas? I'm guessing you read from STDIN but I'm not sure how to do that entirely in this case.

Thanks!

See page http://www.php.net/manual/en/html/function.fopen.html

Pay particular attention to this paragraph:

"If filename is one of "php://stdin", "php://stdout", or "php://stderr", the corresponding stdio stream will be opened. (This was introduced in PHP 3.0.13; in earlier versions, a filename such as "/dev/stdin" or "/dev/fd/0" must be used to access the stdio streams.) "

Yeah I read that but it didn't seem to help me very much. Perhaps I had problems constructing the for loop:

$fd = fopen("php://stdin","r");
while (($data=fgets($fd,1024)) {
// do stuff
}
fclose($fd);

seems to do an infinite loop instead of waiting for the data to be read. I tried it with fread too, and got the same results. I was hoping to try with readline() but I can't find the latest beta to test with.
