$mail gettype'fbl'

A curious command!

$mail gettype 'fbl' is a PHP command that uses the gettype() function to retrieve the data type of a variable.

Here's a breakdown of what's happening:

If you run this command, PHP will likely throw a warning or an error, as fbl is not a valid data type. The output might look something like this:

Warning: gettype() expects parameter 1 to be a variable, string given in [file path] on line [line number]

To fix this, you should replace 'fbl' with a valid variable name or a literal value that you want to check the data type of. For example:

$mail = 'hello';
echo gettype($mail); // Output: string
