If your workflow includes writing code outside of WP Engine’s environment, and you want an easy way to differentiate between a WP Engine environment and another environment in your code, we have just the thing for you!
is_wpe() is a function that we have integrated into our platform to help you determine if you are running on our production environment. It is true if and only if you are on a production WP Engine server.
is_wpe_snapshot() is a similar function that is true if you are running on our staging environment.
So, when is this useful?
If you are developing on a local environment and you want to test whether the site you’re seeing is on WP Engine or not, you can use something like the following as an mu-plugin or theme function:
<?php
if (function_exists('is_wpe') ) {
echo "this site is on WP Engine";
}
else {
echo "you're not on WP Engine";
}
?>This will print “this site is on WP Engine” if the function “is_wpe” is present, which it is on all WP Engine environments. It will print “you’re not on WP Engine” if the “is_wpe” function is not present.
