I think this is more along the lines of what was wanted :)
function custom_function()
{
if( $problem1 )
{
return 'Problem 1 occured!';
}
elseif( $problem2 )
{
return 'Problem 2 occured!';
}
elseif( ... )
{
...
}
return true;
}
if( ($status = custom_function()) === true )
{
echo "Success";
}
else
{
echo $status;
}
Cheers,
Rob.
