preg_match not working

gotissues68

Hello All,
I'm attempting to use the below code in order to match some $_POST data but for some reason its never matching the expression I've given to preg_match I've tried various regexes to gain a match but none seem to be working, the below one should be the simplest but I'm sure its something really simple that I'm missing. Any suggestions as to what I'm doing wrong would be greatly appreciated.

$domain = "$_POST[domain_name]";
$zoneFile = file('/tmp/named.conf');

if (preg_match("/*\"\$domain\"*/", "$zoneFile") == true) {
exit("Zone already exists!");
}

the following code worked, I guess I was trying to make it too complicated.

<?
$domain = "$_POST[domain_name]";
$zoneFile = file_get_contents("/tmp/named.conf");

if (preg_match("/$domain/", "$zoneFile")) {
echo "A match was found.";
} else {
echo "A match was not found.";
}
?>

Well, if that's all you're wanting then it looks like you're still making it more complicated than it needs to be...

[man]preg_match[/man]
Tip: Do not use preg_match() if you only want to check if one string is contained in another string. Use [man]strpos/man or [man]strstr/man instead as they will be faster.
