The statement "if(isset($_POST['name'])" is true.

What is isset function?

The isset function is a built-in function in PHP that is used to determine whether a variable is set and is not null.

In the example you provided, the isset function is being used to test whether the 'name' variable is set in the $_POST associative array.

If the 'name' variable is set in the $_POST array, the isset function will return true, and the code block within the if statement will be executed. If the 'name' variable is not set or is null, the isset function will return false and the code block will not be executed.

So, in the example you provided, the statement "if(isset($_POST['name'])" is true if the 'name' variable is set in the $_POST array, and false if it is not set or is null.
