Question

I know next to nothing about php so this will make someone laugh probably.

I have this bit of code in index.php which checks a host header and redirects if a match is found.

if (!preg_match("/site1.net.nz/",$host)) {
    header('Location: http://www.siteblah.net.nz/temp_internet_block.cfm');
}

However, I need to make it check on potentially multiple sites. as follows.

if (!preg_match("/site1.net.nz/"|"/site2.net.nz",$host)) {
    header('Location: http://www.siteblah.net.nz/temp_internet_block.cfm');
}

This might actually be the correct syntax for all I know:-)

Answer 1

// [12] to match 1 or 2
// also need to escape . for match real . otherwise . will match any char
if (!preg_match("/site[12]\.net\.nz/",$host)) {
    header('Location: http://www.siteblah.net.nz/temp_internet_block.cfm');
}

Or

if (!preg_match("/site1\.net\.nz|site2\.net\.nz/",$host)) {
    header('Location: http://www.siteblah.net.nz/temp_internet_block.cfm');
}
