PHP if URL equals this then perform action

[sphinx]

Hi,

 

I'm using an example below regarding a whole URL. I'm looking for some conditional PHP that will display certain content depending on if the URL contains the word 'liz' if not, display else.

 

$host = $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];
if($host == 'liz-4.website.com') 
{
echo $this->__('The domain contains the word liz.');
}
else
{
echo $this->__('The domain does not contain the word liz.');
}

You have the if statement, but what is this "this" that you use? Why "this"?

Checking if the host string is another string is not the same as checking if the string contains another string.

 

strpos

 

And you should be using HTTP_HOST instead of SERVER_NAME. The former is the actual hostname used in the URL while the second is the name configured in the server. They don't necessarily match (though they often do).

If are looking for the first 3 characters for liz this could work.

if(substr($_SERVER['HTTP_HOST'], 0, 3) == "liz"){
echo "yes";
} else {
echo "no";
}

(this would be better if you did a check if was not your servers actual name)

example:

if($_SERVER['HTTP_HOST'] != "website.com"){
$is_subdomain = true;
}

if(isset($is_subdomain) && substr($_SERVER['HTTP_HOST'], 0, 3) == "liz"){
echo "yes";
} else {
echo "no";
}

below will look only within the subdomain

 

an exact subdomain

$explode_host = explode(".",$_SERVER['HTTP_HOST']);
$subdomain = $explode_host[0];
if($subdomain == "liz-4"){
echo "yes";
} else {
echo "no";
}

anywhere it exists within subdomain as requinix mentioned

$explode_host = explode(".",$_SERVER['HTTP_HOST']);
$subdomain = $explode_host[0];
$pos = strpos($subdomain, "liz");
    if ($pos !== false){
        echo "yes";
    } else {
        echo "no";
    }
