I have a config file which has variables based on the domain of the page (HTTP_HOST)
$c is an array.
eg $c['example.com-user'] is an entry in the config file.
I need to pass the value of $c['example.com-user'] to a function building the variable name on the fly.
I have "example.com" in $host variable
Thanks for any help!
<?php
$c['example.com-user'] = "someval";
$host = "example.com";
echo $c[ $host . '-user'];
?>
Tested, working.
$c[$host.'-user']
Assuming you only ever need the config data for the current domain, might it be easier to have a config file per domain, rather than one monster array with all of them? Then you can just load up the relevant file at the start.
If, for example your domain stored in variable $host and username in variable $user. Then, all you have to do is, use this variables as array's key:
echo $c[ $host . "-" . $user];
if $host = 'inform.com' and $user = 'simple_user', the code above will translate into:
echo $c['inform.com-simple_user'];
You see, to concatenate string, you use '.' (dot).
