<?php
$this->googleMapsApiKey = $this->getValueFromDB("google", "googleMapsApiKey");
if ($_SERVER['HTTP_HOST']=='www.ABC.info') {

} elseif ($_SERVER['HTTP_HOST']=='www.CBA.com') {
$this->googleMapsApiKey = "Googlemap-keys";
}
?>" type="text/javascript"></script>
Thanks a lot!!

Answer 1

You can avoid this whole problem: Maps API keys now support multiple domains (and you can edit authorised domains at any time). See Obtaining an API key for more details.

Answer 2

I totally agree with Wrikken, it does not seem that you echoed the variable during the process. Maybe this approach would help:
<?php
print '<script src="http://maps.google.com/maps?file=api&v=2.x&key=';
$this->googleMapsApiKey = $this->getValueFromDB("google", "googleMapsApiKey");
switch ($_SERVER['HTTP_HOST'])
{
//Specific for a domain, but I think that the default handles it against your DB automatically
//case 'www.ABC.info' : $this->googleMapsApiKey = "Googlemap-keys";
// break;
//Same here
// case 'www.CBA.com': $this->googleMapsApiKey = "Googlemap-keys";
// break;
default: $this->googleMapsApiKey = "Googlemap-keys";
}
echo "$this->googleMapsApiKey type=\"text/javascript\"></script>";
?>
