Further Documentation:
The function takes one parameter:
$key, which is the API key entered by the user to validate.
The function initializes an empty string called
$msg, which will store a message to return to the user based on the validation result.
If
$key is empty, the function sets
$msg to a message encouraging the user to enter their API key to enable certain features.
If
$key is not empty, the function uses two regular expressions to validate the format of the key. The regular expressions check that the key is a string of 5 alphanumeric characters, followed by a hyphen, and repeated 5 times for a total of 25 or 24 characters. If the key does not match either of these patterns, the function sets
$msg to an error message indicating that the key is not valid.
If
$key matches one of the valid patterns, the function sets
$msg to a success message indicating that the key is valid.
Finally, the function returns the message stored in
$msg.
Overall, this function provides a simple way to validate an API key entered by a user, and can be used to provide feedback to the user about the validity of their input.
