Invalid argument supplied for foreach() to 'No routes found'

[AFVA | Mitchell]

Just wondering if anyone had the code to stop the Invalid argument supplied for foreach() and instead replacing it with 'No routes found' when no results are returned.

I used to know the code but forgot it.

Thanks!

How about ->

<?php
if (!$variable)
    {do something if the array is empty}
else
    {do something if the array has data}
?>

I would use:

if(!is_array($variable))
{  
    echo 'No routes found';
    return;
}

Though you can also use

!$variable

I'm updating my code to use !is_array() though
