regex help

[gotissues68]

I'm trying to modify a text file to remove 4 lines with a given variable located in it.

For instance

zone "blah.net" {
type master;
database "mysql named blah 127.0.0.1 <> <>";
};

Someone posts to a page and has entered blah.net as the domain they'd like to remove from the file I'd like to remove the first line that it occurs in and the 3 lines below it. I have something that works via system()

system("awk '/\"$_POST[domain]$_POST[extension]/ {x=4}; {if (x) {x--} else {print}}' /tmp/named.conf > /tmp/named.modified");

but thats a pretty ugly hack to make it work, I'd prefer to open the original file named.conf and write out the file normally versus saving it to a new file. Any suggestions are greatly appreciated.

i tried this out in the debugger and the regex worked fine.

$zoneFile = file_get_contents("/tmp/named.conf");
$domain = "blah.net";

$newFile = preg_replace("/\s?zone \"$domain\" {\s+.*\s+.*\s+};\s?/i", "", $zoneFile);

$fp = fopen("/tmp/named.conf", "w+");
fwrite($fp, $newFile);
fclose($fp);

?>

the \s? at the beginning and end of the regex is there so you dont end up with a bunch of extra whitespaces from having a bunch of records deleted.
let me know how that works for you and if you need it changed at all.

Thank you very much! Works exactly how I needed it to. What debugger are you using?

im running zend studio 3.0.2. its a really nice php ide where you can run your code (most of it at least) and it produces the text output right in the debugger window. its really nice for testing small code. saves the time of having to open the ftp client, connect, edit the remote file, upload, type in in the browser and then fix errors. it has a lot more power than i utilize but i really only use it for saving the time of writing small pieces of code. here is a link to it: http://www.zend.com/store/products/zend-studio.php
they offer a trial download so you can test it out fully before you buy.
