My Answer:
To hide the output of a PHP function if it returns no value, you can use an `if` statement to check if the function returns a value before displaying it. Here is an example:

php
function myFunction() {
// Your function code here
// Return a value if it exists
}

$output = myFunction();

if ($output) {
echo $output;
}
?>


In this example, the `myFunction()` function is called and its output is stored in the `$output` variable. Then, an `if` statement checks if the `$output` variable has a value. If it does, the output is displayed using `echo`. If the function does not return a value, nothing will be displayed.
