Answer 1

You need use the extension_loaded function of SPL

$sExtensionName = 'geoip';
if (!extension_loaded($sExtensionName)) {
    exit("Error extension {$sExtensionName} not loaded");
}

Reference function.extension-loaded.php

Answer 2

I am not sure what do you mean by via PHP CODE.

If you are trying to check enabled PHP extension in your web server without using Terminal/SSH or any commands, then you can try the described way to check using your browser.

Create a PHP file(file with .php extension). for example, checkEnabledExtension.php

Now edit the file and add the following codes and save it:

<?php

$extensionName = "mysqli"; // replace mysqli by the extension name your want to check. for example: $extensionName = "geoip"; I am not sure about the name of the geo_ip extension.
echo $extensionName;
if(extension_loaded($extensionName)) {  // check extension_loaded() in PHP manual for details
    echo ": is Enabled."; // if the extension is enabled this block will run
} else {
    echo ": is NOT Enabled."; // this block will run if the extension is not enabled
}

?>

Now upload the file to your web root directory. For example: if your domain name is example.com then upload it to web root/public_html of the example.com

Now in your browser go to domain.com/checkEnabledExtension.php

That is it. You will see if the extension is enabled or not.

To check a list of all enabled extension:

use this PHP codes in checkEnabledExtension.php file to get the list of all enabled php extensions instead of checking a single. Use the same procedures above just use these codes:

<?php

print "<pre>"; print_r(get_loaded_extensions()); print "</pre>"; // this will print a list of all enabled PHP extension 

?>
