We needed to get the WordPress version with PHP code and we found a global WordPress variable that you can use to access that. All of WordPress’ global variables can be found at https://codex.wordpress.org/Global_Variables.
In order to access the current WordPress version, you need to add the following to your function:
global $wp_version;
Then, you can reference that variable later on in the function and it’ll throw you the current WordPress version:
echo 'WordPress Version'.$wp_version;
Here’s what the full function would look like:
public function example_function(){
global $wp_version;
echo 'WordPress Version'.$wp_version;
}
If you need to access several WordPress global variables, check out our post on accessing multiple global variables in a function.
